What Causes Sensitive Teeth?

If you sometimes find the taste of something hot or cold painful on your teeth, you may suffer from sensitive teeth.

Sensitive teeth is a common problem which may be caused by cavities and fractured teeth.

But it can also be caused by worn tooth enamel, a cracked tooth or an exposed tooth root.

Tooth enamel is the strongest substance in the body and it protects the crowns of healthy teeth. A layer called cementum protects the tooth root under the gum line.

The part underneath the enamel and the cementum is called dentin, which is less dense than enamel or cementum.

The dentin contains small hollow tubes or canals called tubules. When the dentin loses its protective covering, the tubules allow hot, cold, acidic or sticky foods to reach the nerves and cells inside the tooth.

This causes hypersensitivity and occasional discomfort but fortunately, the irritation does not cause permanent damage.

Following proper oral hygiene helps prevent the gums from receding and causing the pain of sensitive teeth.

Brushing your teeth incorrectly or even brushing too much can cause gum problems.

Your dentist will advise you on the best daily routine to maximize your oral hygiene.

Why cavities aren't just for kids

Tooth decay or cavities result from destruction of the tooth enamel and can lead to a range of problems from toothache to bad breath.

Cavities occur when foods containing carbohydrates (sugars and starches) such as milk, sugared drinks, cakes or candy are frequently left on the teeth.

Bacteria that live in the mouth thrive on these foods, producing acids as a result. Over a period of time, these acids destroy tooth enamel, resulting in tooth decay.

Many people associate cavities with children but the changes that occur with aging make cavities an adult problem, too.

Recession of the gums away from the teeth, combined with an increased incidence of gum disease, can expose tooth roots to plaque.

Tooth roots are covered with cementum, a softer tissue than enamel. They are susceptible to decay and are more sensitive to touch and to hot and cold. The majority of people over age 50 have tooth-root decay.

Decay around the edges of fillings is also common to older adults. As many of them did not benefit from fluoride and modern preventive dental care when they were younger, they often have a number of dental fillings.

Over the years, these fillings may weaken, fracture and leak around the edges.

Bacteria accumulate in these tiny crevices causing acid to build up which leads to decay.

You can help prevent tooth decay by following these tips:

– Brush twice a day with fluoride toothpaste
– Clean between your teeth daily with floss or interdental cleaner
– Eat nutritious and balanced meals and limit snacking

Its also worth asking your dentist about supplemental fluoride, which strengthens your teeth, and about dental sealants, a plastic protective coating which is applied to the chewing surfaces of the back teeth to protect them from decay.

In addition, its important to visit your dentist regularly for professional cleanings and oral examination.

Why its not inevitable that you'll lose your teeth as you get older

Advancements in dental techniques and the increased focus on preventive dentistry means older adults are keeping their natural teeth longer than ever before.

A survey by the National Institute of Dental and Craniofacial Research showed that the rate of toothlessness in the 55 to 64 age group has dropped 60 percent since 1960.

Whatever your age, its important to practice good oral hygiene at home and to visit your dentist regularly. A few simple steps can help you maintain good oral health throughout your life.

Plaque, the sticky, colorless layer of bacteria that causes tooth decay and gum disease, can build up quickly on the teeth of older adults, particularly when they neglect oral hygiene. This can increase the risk for tooth decay and periodontal disease.

So its important to brush your teeth twice a day with fluoride toothpaste, and clean between your teeth daily with floss or interdental cleaners.

Regular dental checkups are also an important part of caring for your teeth.

This can help you save your teeth and gums and prevent other dental problems. It will save you time and money in the long-run as well.

Taking steps to stop oral cancer before its too late

Oral cancer hits more than 30,000 Americans every year but you can minimize the risk by taking steps to ensure its caught early enough.

The first indications of oral cancer may be a very small, but dangerous, oral spot or sore that you are not even aware of.

In a routine examination, your dentist will carefully examine the inside of your mouth and tongue.

If they notice a flat, painless, white or red spot or a small sore, this may be completely harmless. But harmful spots or sores often look the same as harmless ones.

To ensure that a spot or sore is not dangerous, your dentist may choose to perform a simple test, such as a brush test. This collects cells from the lesion which can them be analyzed.

Any positive results from a brush test must usually be confirmed by a biopsy before deciding the next step.

If precancerous cells are found, the lesion can be surgically removed if necessary during a separate procedure.

When caught early enough, the chances of preventing the cancer developing are high but only half of those diagnosed survive more than five years.

Thats why regular dental examinations are so important for your overall health and not just to have good teeth.

The power of panoramic x-rays

X-rays are extremely valuable for helping dentists identify issues that may not show up on normal oral examination.

The three most common types of dental X-rays are the bitewing, periapical and panoramic X-rays.

Panoramic X-rays give a broad overview of the entire mouth – supplying information about the teeth, upper and lower jawbone, sinuses, and other hard and soft tissues of the head and neck.

Unlike other X-rays, where the film is placed inside the patients mouth, the panoramic film is contained in a machine that moves around the patient’s head. So they are very easy to use.

Panoramic X-rays are often used to check wisdom teeth but they will also reveal deep cavities and gum disease. They are also useful to help patients with past or present jaw problems or those who require full or partial removable dentures, dental implants, or braces.

They can also be valuable in assisting people who are suspected of having oral cancer or have had recent trauma to the face or teeth.

Panoramic X-rays play an important role in thorough dental examinations and are recommended at least every five years or so for most patients.

How to make your smile brighter

Your smile makes a huge difference to what people think about you and how you feel about yourself.

And there are many options available to help you improve the look and brightness of your smile, including:

In-office bleaching: During chair-side bleaching, the dentist will apply either a protective gel to your gums or a rubber shield to protect the oral soft tissues. A bleaching agent is then applied to the teeth, and a special light may be used to enhance the action of the agent.

At-home bleaching: There are several types of products available for use at home, which can either be dispensed by your dentist or purchased over-the-counter. These include peroxide bleaching solutions, which actually bleach the tooth enamel. Peroxide-containing whiteners typically come in a gel and are placed in a mouth guard.

Whitening toothpastes: All toothpastes help remove surface stain through the action of mild abrasives. “Whitening” toothpastes include special chemical or polishing agents that are more effective at removing stains. However, unlike bleaches, they don’t alter the intrinsic color of teeth.

Start by speaking to your dentist. He or she will tell you if whitening procedures would be effective for you as whiteners may not correct all types of discoloration.

The early years of dentistry and teeth

Although there have been huge advances in dental care in recent years, there are records of people dealing with teeth going back over thousands of years.

Here are some of the key dates from the early years in the development of dentistry.

5000 BC: A Sumerian text describes tooth worms as the cause of dental decay.

2600 BC: Hesy-Re, an Egyptian scribe, often called the first dentist, dies. An inscription on his tomb includes the title the greatest of those who deal with teeth, and of physicians.

500-300 BC: Hippocrates and Aristotle write about dentistry, including the eruption pattern of teeth, treating decayed teeth and gum disease, extracting teeth with forceps, and using wires to stabilize loose teeth and fractured jaws.

166-201 AD: The Etruscans practice dental prosthetics using gold crowns and fixed bridgework.

500-1000: During the Early Middle Ages in Europe, medicine, surgery, and dentistry, are generally practiced by monks, the most educated people of the period

700: A medical text in China mentions the use of silver paste, a type of amalgam.

1130-1163: A series of Papal edicts prohibit monks from performing any type of surgery, bloodletting or tooth extraction. Barbers often assisted monks in their surgical ministry because they visited monasteries to shave the heads of monks and the tools of the barber trade sharp knives and razors were useful for surgery. Following the edicts, barbers assume the monks surgical duties: bloodletting, lancing abscesses, extracting teeth, etc.

1210: A Guild of Barbers is established in France. Barbers eventually evolve into two groups: surgeons who were educated and trained to perform complex surgical operations; and lay barbers, or barber-surgeons, who performed more routine hygienic services including shaving, bleeding and tooth extraction.

1400s: A series of royal decrees in France prohibit lay barbers from practicing all surgical procedures except bleeding, cupping, leeching, and extracting teeth.

How mouth protectors can save your teeth

If you take part in sports that carry a significant risk of injury, you should wear a mouth protector.

Accidents can happen during any physical activity and, if you participate in sports such as football, hockey, basketball, baseball, gymnastics and volleyball, you might be grateful for the extra protection one day.

Something as simple as a misdirected elbow in a game, or a spill off a bicycle, can leave you with chipped or broken teeth, nerve damage to a tooth or even tooth loss.

Mouth protectors usually cover the upper teeth and they can cushion the effect of a blow to the face, reducing the risk of broken teeth and injuries to the soft tissues of the mouth.

In addition, if you wear dental appliances such as braces on your lower jaw, your dentist may suggest a mouth protector for these teeth as well.

A properly fitted mouth protector will stay in place while you are wearing it, making it easy for you to talk and breathe. The three main types of mouth protectors are:

Stock: These are inexpensive and come ready to wear. But they often don't fit very well and they can be bulky making breathing and talking difficult.

Boil and bite: These can also be bought at many sport stores and may fit better than stock mouth protectors. You first soften them in water, then insert them and allow them to adapt to the shape of your mouth.

Custom-fitted: Protectors that are specially made for you by your dentist are more expensive but are likely to fit better than one you buy off the shelf.

Choosing to wear the right mouth protector can help you avoid serious long-term damage to your teeth and mouth.

How sugar in your diet affects your teeth

The sugar content in the food you eat has a big effect on your teeth and gums.

When bacteria (plaque) come into contact with sugar in the mouth, acid is produced, which attacks the teeth for 20 minutes or more. This can eventually result in tooth decay.

That's why drinking sugar-filled sodas, sweetened fruit drinks, and non-nutritious snacks can take a toll on teeth.

This is particularly true for children as their eating patterns and food choices affect how quickly they develop tooth decay.

Foods that contain sugars of any kind can contribute to tooth decay. However, almost all foods, including milk or vegetables, have some type of sugar. Many of them also contain important nutrients that are an important part in our diet.

To help control the amount of sugar you consume, read food labels and choose foods and beverages that are low in added sugars. Soft drinks,candy, cookies and pastries often contain added sugars.

How scaling and planing can help clean your teeth properly

Dental plaque is a film that builds up on your teeth and, if it is not removed through good oral hygiene, it can lead to tooth decay and gum problems.

Over time it can ultimately form a hard, rough sediment known as dental tartar or calculus, which attracts further plaque buildup.

Calculus has to be removed by a trained professional such as a hygienist or dentist.

They may do this by manual tooth scaling or using an ultrasonic device.

If the buildup is light or moderate, the dentist or hygienist may use manual scaling instruments of various shapes and sizes.

If the buildup of tartar and stains is heavy, an ultrasonic cleaner may be used. This may be followed by hand scaling.

Build up of plaque can cause inflammation of the gums leading to breakdown of the connection between the teeth and the supporting structures.

Root planing is a procedure to treat gum disease by thoroughly scaling the roots of teeth to establish a smooth, calculus-free surface.

This treatment may require local anesthesia to prevent pain. Thorough periodontal scaling customarily involves several dental visits

If conditions are more advanced, surgery may be needed for complete debridement of the roots to arrest the disease process.

Some people tend to have more buildup of calculus than others and some may be more prone to periodontal inflammation or the development of tooth decay.

It’s therefore important to follow your hygienist’s advivce on how often to return for regular cleanings – even if your insurance only covers two a year.

Why a dental abscess should be treated quickly

If you have any kind of swelling in your gum, it almost certainly indicates a serious infection that should be treated urgently.

Dental abscesses result from a bacterial infection in the teeth or gums.

For example, it may come from an untreated cavity. Cavities result when some of the bacteria in our mouths mix with sugars and starches in our diet to produce acid.

This acid attacks the hard enamel coating of our teeth and, as the cavity gets deeper, it eventually infects the nerve and blood supply of the tooth.

In some cases, a dental abscess is caused by an infection of the gum. Bone loss from gum disease can create a pocket between the tooth, gum and bone.

When bacteria and other debris get into this pocket, an abscess can form.

The treatment for an abscess depends on how severe the infection is.

If the abscess has been caused by decay, root canal treatment may be needed or the tooth may even have to be removed.

If the abscess has been caused by the gum, the gum will need deep cleaning or surgical treatment. Again the tooth may need to be removed.

Sometimes, a small incision may be made into the gum to drain the abscess. If this happens, antibiotics and pain medication may be used to relieve discomfort.

If you wait until the gum is severely swollen before seeking treatment, the situation can become very serious.

The abscess at this stage can prevent you breathing properly and can be life-threatenting.

So if you have any signs of swelling in your gum, contact your dentist immediately.

The power of panoramic x-rays

X-rays are extremely valuable for helping dentists identify issues that may not show up on normal oral examination.

The three most common types of dental X-rays are the bitewing, periapical and panoramic X-rays.

Panoramic X-rays give a broad overview of the entire mouth – supplying information about the teeth, upper and lower jawbone, sinuses, and other hard and soft tissues of the head and neck.

Unlike other X-rays, where the film is placed inside the patients mouth, the panoramic film is contained in a machine that moves around the patient’s head. So they are very easy to use.

Panoramic X-rays are often used to check wisdom teeth but they will also reveal deep cavities and gum disease. They are also useful to help patients with past or present jaw problems or those who require full or partial removable dentures, dental implants, or braces.

They can also be valuable in assisting people who are suspected of having oral cancer or have had recent trauma to the face or teeth.

Panoramic X-rays play an important role in thorough dental examinations and are recommended at least every five years or so for most patients.

What to do if your tooth cracks

While our teeth are normally very strong, they can crack for a number of reasons.

Reasons could include tooth decay, trauma/injury, grinding of the teeth or a stress fracture.

Sometimes, our jaw may be stronger than our teeth and the teeth can fracture when we bite heavily on food.

We can protect our teeth in some circumstances – for example it may be advisable to wear a mouthguard during sports.

Taking proper care of the teeth and regular visits to the dentist will help keep your teeth in good shape.

If a tooth cracks, it may become painful if the nerve is exposed and the area can become tender.

If this happens, rinse your mouth with warm water to clean the area and apply a cold compress to reduce swelling. Then call your dentist immediately.

Treatment will depend on where the tooth has fractured, how close it is to the nerve and the overall condition of the tooth.

A cracked tooth may be repaired with silver alloy, gold, porcelain or plastic. Or it may require a crown or overlay or bonding, which applies porcelain or enamel to the fractured tooth.

If you contact your dentist quickly, they will be able to take the most appropriate action to preserve the tooth as much as possible.

How cosmetic dentistry can change your smile – and your life

Modern cosmetic dentistry has created many opportunities that did not exist before for people to improve their appearance and change the way they feel about themselves.

Although cosmetic dentistry really did not exist a few yaears ago, it now attracts interest from a wide range of people.

There are few people who don’t want to improve their appearance by making their teeth straighter and whiter so that they look better when they smile.

New technology and procedures have created many more opportunities for dentists to help patients look better.

One of the most important opportunities for doing this is porcelain veneers.

These are custom-made wafers that the dentist places over the front of the teeth to repair damage and make them look better.

They can overcome many cosmetic dental problems such as whitening stained or discolored teeth, closing gaps between teeth or correcting a crooked smile without the need for braces.

They can also cover up chips and imperfections so that the smile looks much better.

Another important cosmetic trend is the increased use of white fillings.

White fillings now are more lifelike than ever and they last longer than previously.

They have become the material of choice for many dentists as they blend in with teeth and look better.

If you feel your smile is less than perfect, talk to your dentist about how it could be better.

Diabetes and your dental health: How your dentist can help

If you've been diagnosed with diabetes, its important that you let your dentist know so that they can give you the best care possible.

As more than 15 million Americans have diabetes, your dentist will be familiar with the issues and will give you the specialist care you need.

This is important because diabetes can lower your resistance to infection and slow the healing process.

Its important to tell your dentist:

– If you have been diagnosed with .diabetes
– If the disease is under control
– If there has been any other change in your medical history
– Names of all prescription and over-the-counter drugs you are taking

The most common oral health problems associated with diabetes are:

– Tooth decay
– Periodontal (gum) disease
– Salivary gland dysfunction
– Fungal infections
– Infection and delayed healing
– Taste impairment

If you have regular dental checkups and keep your dentist informed about your status theyll be able to help you reduce and manage these risks.

Making the most of your smile

Your smile is a major factor in the impression people get when they meet you.

And the good news is that you now don’t have to settle for a smile spoiled by stained, chipped, or misshapen teeth.

Advances in dental treatment mean there is a wide range of choices to help you get the smile that you want. Here are some of the options:
– Tooth whitening (bleaching) can help brighten teeth that have become discolored or stained. It can be done in the dental office or with a system the dentist can give you to use at home
– Bonding improves the appearance of teeth that have become chipped, broken, cracked or stained. This is done by bonding tooth-colored materials to the tooth surface
– Enamel shaping involves modifying teeth to improve their appearance by removing or contouring enamel
– Veneers are thin custom-made shells of tooth-colored materials designed to cover the front side of teeth. They are used to treat spaces between teeth and teeth that are chipped, stained or poorly shaped.
– Braces may be needed if teeth are crooked, crowded or do not meet properly – and not just for kids

Even small changes can have a big impact on your smile and so make a huge difference to how you look and how you feel about yourself.

If you’d like an even better smile, your dentist will be able to give you information about the options available.

Why your routine dental cleaning is not routine

For many patients, the dental cleaning appointment may seem little more than a more complicated version of brushing your teeth.

However, this appoinment plays a crucial role in patient education and prevention of dental disease.

The appointment is called a dental prophylaxis, or prophy and it’s one of the most important steps in your dental care program.

Here are some of the elements that it may include, depending on your needs:

– Oral hygiene evaluation

– Tooth brushing and flossing instructions

– Scaling above the gum to remove plaque and tartar

– Debridement of tartar beneath the gum

– Polishing the teeth

– Periodontal charting

It’s important to remove plaque from the teeth as it ultimately forms a hard, rough sediment known as tartar or calculus, which must be removed by a dental professional to help prevent periodontal disease.

Polishing the teeth removes stains and creates a feeling of fresh breath and a clean mouth.

The hygienist or dentist may recommend a prophylaxis visit every two to six months.

Although insurance may only cover two prophies a year, recall frequency depends on many factors and should be based on individual needs.

These appointments can help you have much better dental health and could save you a great deal of time and money in the long run.

The keys to keeping your mouth healthy

A healthy mouth is a good indication of your overall health and helps you to keep a great smile and continue eating what you want for many years to come.

There are a few steps you can take to make sure your mouth is as healthy as possible:
– Brush your teeth twice a day using a good quality toothbrush
– Renew your toothbrush regularly. It will only keep your mouth healthy if the brush is in good condition and the bristles are strong. You should replace it at least every three or four months
– Clean between your teeth. Your toothbrush can’t reach everywhere and bacteria can linger between the teeth so it’s important to clean between them every day using floss or an interdepartmental cleaner
– Visit your dentist regularly for professional cleaning and oral examinations

Your dentist will be able to give you tips on what other products you should consider to help improve your oral health.

For example, antimicrobial mouth rinses and toothpastes can reduce the germs in your mouth and reduce the risk of gum disease.

Also, fluoride mouth rinses can help reduce and prevent tooth decay. Studies have shown that using mouth rinses provides valuable protection over and above that provided by fluoride toothpaste alone.

Look out for the ADA seal when buying toothbrushes and other dental products. This is a sign that the product has met American Dental Association standards for safety and effectiveness.

Following these steps can help ensure that you continue to enjoy great oral health.

Action steps to prevent gum disease

Gum disease is a major cause of tooth loss in adults but it can be prevented or reversed if you take the right steps.

Its caused by plaque a sticky film of bacteria that constantly forms on the teeth. These bacteria create toxins that can damage the gums.

However, you can help avoid gum disease by caring properly for your teeth and having regular dental checkups. These are some steps you can take to keep your teeth and gums healthy:

Brush your teeth well twice a day: This removes the film of bacteria from the teeth. Be sure to use a soft-bristled toothbrush that is in good condition. Toothpastes and mouth rinses containing fluoride strengthen the teeth and help prevent decay.

Clean between your teeth every day: You need to remove the bacteria and food particles that a toothbrush can’t reach so you should clean between your teeth with floss or interdental cleaners every day. Your dentist will show you how to do this properly without injuring your gums.

Even if you already have early stage gum disease, it can often be reversed by daily brushing and flossing.

Eat a balanced diet: A good diet based on a variety of foods from the basic food groups, such as grain products; fruits; vegetables; meat, poultry and fish; and dairy products will help your teeth. Its also a good idea to limit snacks between meals.

Visit your dentist regularly: To prevent gum disease, its important to have regular dental checkups and professional cleaning.

Taking the right steps will help you avoid gum disease and can even reverse it if you catch it in the early stages.

Is it safe to have an X-ray while pregnant?

Some women worry about whether its safe to have an X-ray exam while they are pregnant.

This can cause them to put off treatment they need.

However, untreated dental infections can pose a risk to the fetus, and dental treatment may be necessary to maintain the health of the mother and child. Sometimes this will mean an X-ray is necessary.

Radiation from dental X-rays is extremely low but every precaution is taken to minimize radiation exposure.

For example, a leaded apron reduces exposure to the abdomen and should be used when a dental radiograph is taken.

In addition, a leaded thyroid collar can protect the thyroid from radiation, and should be used whenever possible. The use of a leaded thyroid collar is strongly recommended for women of childbearing age, pregnant women and children.

Overall there is no reason to avoid dental radiographs (X-rays) while pregnant, breastfeeding or trying to become pregnant.

Follow your dentists advice and ask questions if you have any concerns.
