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 routint to maximize your oral hygiene.

Taking steps to stop oral cancer before it’s too late

Oral cancer hits more than 30,000 Americans every year but you can minimize the risk by taking steps to ensure it’s 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.

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