Common Reasons for Tooth Sensitivity

If your teeth hurt when you eat hot or cold foods, it’s not the time for thinking about quitting eating these foods. Rather you should think about getting the root cause fixed. According to Academy of General Dentistry (AGD), about 40 million adults suffer from the problem of tooth sensitivity. The first thing you need to do is to visit your dentist in order to know about the root cause of tooth sensitivity.

Origin of Dentin Hypersensitivity

The inside of a tooth usually consists of a porous material called dentin which further encloses pulp that contains nerves and vessels. The dentin also reacts to hot and cold temperature due to the some active nerves it contains. The hard outer layer, called tooth enamel, covers the dentin. This tooth enamel does the job of protecting inner part of tooth, hence preventing tooth from getting sensitive to hot and cold temperatures. When this enamel wears out due to any reason, the hot and cold temperatures find no resistance in reaching the dentin and pulp, leading to dentin hypersensitivity or nerve irritation.

There can be many reasons for tooth sensitivity.

  • Wearing out of enamel due to the use of toothbrush with hard bristles. Abrasive brushing can also be the reason in this regard
  • Enamel erosion due to the consumption of acidic foods and beverages
  • Exposure of dentin due to tooth decay, broken teeth, or leaky fillings
  • Exposure of tooth’s root due to gum recession.
  • Teeth grinding at night
  • Sensitivity after teeth whitening procedure

Getting treatment for tooth sensitivity

The first thing you need to do is to talk to your dentist about the issue. Dentists are qualified people who can determine the course of action based on symptoms. In some cases, the dentist may not even need to do advanced analysis as symptoms could make the case pretty clear. And if the advanced analysis is required, it can also be done in order to know about the root cause of tooth sensitivity. Hence, you dentist will be able to treat your problem in the best possible way.

After knowing the reason, your dentist will work on the root cause to treat the problem.

Products you can use

While you can get ultimate treatment for tooth sensitivity from your dentist, there are also some products which you can use to reduce tooth sensitivity at home. In the dentist’s office, you get fluoride gel applied to your sensitive teeth. On the other hand, over-the-counter products offer reduction in sensitivity as they block the nerve ending in the teeth. Furthermore, you can use toothpaste which is specifically made to reduce sensitivity. You can use such products to get rid of the tooth sensitivity.
