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.

Different types of fillings and restorations

Nowadays, thanks to advances in dental techniques and materials, patients have a much wider range of choices when they have to repair missing, worn, damaged or decayed teeth.

For example, materials such as ceramics and polymer compounds that look more like natural teeth help dentists create pleasing, natural-looking smiles.

The traditional materials such as gold, base metal alloys and dental amalgam are still widely used as they have many advantages.

The strength and durability of traditional dental materials continues to make them useful in many situations. For example, they are good when fillings are required in the back teeth because the pressure of chewing is high in that area.

The choice of the best option will depend on several factors such as the patient’s oral and general health, where and how the filling is placed and the number of visits needed to prepare and adjust the restored tooth.

The choice about which option is best depends on each individual’s needs so you should discuss the options with your dentist.
