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.

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.

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 approriate action to preserve the tooth as much as possible.

Some tips on overcoming nerves when going to the dentist

Some people get a bit nervous about the idea of going to the dentist.

As a result of the major progress that has been made in diagnosis and treatment, the process gets more comfortable all the time. So you may be worrying unnecessarily.

But, if you’re in any way tense or anxious, tell your dentist and the dental staff.

They will understand and will be able to adapt the treatment to your needs.

It can also help if you choose a time for your dental visit when you’re less likely to be rushed or under pressure. Dashing out from a busy day at work may make you feel more stressed.

For many people, that means making an early-morning or a Saturday appointment helps a great deal.

There are also other steps than can help. If the sound of the drill bothers you, take a portable audio player and headset so you can listen to your favorite music.

You can also help to relax by simply visualizing yourself somewhere you feel relaxed.

Sometimes these simple steps can help you feel a lot better. So why not give it a try on your next visit?
