I have sensitive teeth. What can I do?

If brushing or flossing are harmful you, or if a taste of ice cream or some coffee is something painful, this means you have sensitive teeth.

Many people suffer from sensitive teeth and it can start at any time. Reading this article you will find information about the causes of sensitive teeth, you will find some tips in order to reduce this kind of sensitivity and also some treatment solutions.

What is the cause of sensitive teeth?

The part of tooth we can see has a layer of enamel that protects the softer dentin underneath. If the dentine is exposed, a tooth can become sensitive. This usually happens where the tooth and the gum meet and the enamel layer is much thinner. The dentin contains tubules (small hollow tubes or canals). When dentin loses its protective covering, these tubules allow heat and cold or sticky foods to reach the nerves and cells inside the tooth. Dentin may also be exposed when gums recede. The result can be hypersensitivity.

Below are some causes of dentin hypersensitivity:

  • Brushing too hard. If you brush too hard, use a hard-bristle toothbrush, you can wear down enamel and expose the dentin.
  • Tooth grinding. This habit can cause the enamel of tooth to be worn away, making the teeth sensitive.
  • Tooth decay.
  • Gum disease. Plaque and tartar can cause the gum to recede down the tooth. If periodontal disease is left untreated, gum tissues can separate from the teeth and form spaces called pockets that provide a home for bacteria. This disease can progress until the bone and other tooth-supporting tissues are destroyed, leaving root surfaces of teeth exposed.
  • A cracked tooth or feeling. A crack can run from the biting surface of a tooth down towards the root. Extreme temperatures, especially cold, may cause discomfort.
  • Acidic foods. Foods and drinks with a high acid content, like citrus fruits and pickles can wear down your enamel.
  • Tooth-whitening products. Some patients may have sensitivity for a short time during bleaching or afterwards.

Tips to reduce the teeth sensitivity

  • Brush twice a day, floss daily and rinse your mouth. Use a soft-bristled toothbrush. Brush gently around gum line. Use a toothpaste for sensitive teeth.
  • Have acidic drinks or sugary foods not so often. Try to have them just with the meals..
  • Use a night guard if you grind your teeth.
  • Visit your dentist regularly, at least twice a year.


Depending on what causes your teeth sensitivity, the dentist may recommend you a variety of treatments, as you can see below:

  • Desensitizing toothpaste. It contains compounds that help block sensation traveling from the tooth surface to the nerve. This toothpaste usually require several applications before the sensitivity is reduced.
  • Fluoride gel. It is an in-office technique which strengthens tooth enamel and reduces the transmissions of sensations.
  • A crown or a filling to correct a flaw or decay that results in sensitivity.
  • Root canal. If sensitivity is severe and cannot be treated, your dentist may recommend you this treatment to eliminate the problem.
