5 main causes and what to do in case of tooth sensitivity

Sensitivity in teeth happens when there is some type of wear of the tooth enamel, exposing the dentin, which is an inner layer that surrounds the nerves of the teeth. The exposure of sensitive parts of the teeth causes a sensation of pain and discomfort, which can be triggered by contact with hot, cold, sweet or acidic drinks or foods, and the intensity varies according to the size of the wear and area. of exposed dentin.

To treat this alteration and relieve the symptoms, it is necessary to consult with the dentist, who may indicate strengthening the sensitized areas with options such as toothpaste or fluoride varnish, and, if necessary, restoring the areas that have lost nail polish.

Main causes

1. Too aggressive brushing

Brushing your teeth more than 3 times a day or with a hard bristle brush can cause the tooth enamel to wear down, resulting in increased sensitivity.

2. Gingival recession

Gingival recession, which is when there is a decrease in the amount of gum that covers one or more teeth, can happen due to dental diseases or wrong brushing and results in greater exposure of dentin, which is a tissue that makes up the tooth and which is located close to the root, making the teeth more sensitive, in addition to increasing the risk of infections.

3. Grinding teeth at night

Bruxism, which is a condition in which a person involuntarily grinds their teeth at night, can result in the wear and tear of the enamel of several teeth, increasing sensitivity.In addition to increased sensitivity in the teeth, grinding the teeth can result in problems with the joint that connects the jaw to the skull.

4. Dental treatments

Dental treatments such as teeth whitening, cleaning or restoration can increase the sensitivity of the teeth as they cause a temporary erosion of the tooth enamel.

5. Consumption of very acidic or citrus foods

Some foods can wear down tooth enamel and favor the appearance of cavities, which can make teeth more sensitive. Foods that are too acidic or citrusy, such as lemon, vinegar, and pineapple, or too sweet, such as cakes and chocolates, for example, can increase tooth sensitivity.

How the treatment is done

To treat sensitive teeth, the dentist will investigate the cause and may guide some treatments, such as:

  • Application of fluoride varnish to exposed areas to help restore the enamel;
  • Using foam or fluoride gel in contact with the teeth for a few minutes to strengthen the tooth surface and relieve sensitive areas;
  • Restoration of areas that lost enamel, to waterproof the dentin surface;
  • Laser treatment containing analgesic and anti-inflammatory action to reduce hypersensitivity and accelerate the composition of the layer that covers the teeth;
  • Surgery to correct receding gums if this is the cause of tooth sensitivity.

Also, some precautions should be followed at home to prevent wear and tear and help with treatment, such as not using force when brushing, using mouthwashes that contain fluoride, and using a toothpaste specially formulated to relieve tooth sensitivity., such as Sensodyne, Colgate sensitive, Oral B pro-sensitive or Aquafresh sensitive, for example.
