Do You Suffer From Sensitive Teeth?

sensitive_teeth_dentists_toronto_3D_DentistryMany people suffer from sensitive teeth. It is often described as anything from a mild discomfort to a sharp pain on the surfaces of the teeth, usually triggered by hot, cold, sweet, and sour foods or drinks. It can happen at any age and to anyone. The pain from sensitive teeth is caused by exposed areas on the teeth not protected by enamel, such as the root surfaces. Dentin, which lies below enamel and covers the entire tooth, including root surfaces, is less tolerant and less resistant to environmental changes than enamel. Enamel provides insulation to the tooth that dentin does not. Fluid movement within the dentin produces nerve impulses in the tooth when we eat and drink which can translate as pain and sensitivity.

Common Causes of Sensitive Teeth

The most common causes of tooth sensitivity are receding gums. Recession can be caused by gum disease, aggressive tooth brushing with a hard or medium bristle brush, or be part of the natural aging process. An acidic diet may also play a role in wearing away the protective layer of the teeth, exposing the dentin. Food and drinks high in acid such as carbonated sodas and citrus foods erode and dissolve the enamel leaving the dentin extremely sensitive. A high acidity level in the mouth, created by specific medical conditions such as Bulimia and Gastroesophageal Reflux Disease (GERD) can also result in dental erosion and tooth sensitivity.

What You Can Do to Avoid Tooth Sensitivity

  • Use low abrasion, desensitizing toothpastes such as Sensodyne, Colgate Sensitive or Crest Pro-Health.
  • Switch to a soft-bristle toothbrush to protect the gums and minimize damage to exposed dentin.
