Treating Sensitive Teeth

Sensitive teethDoes drinking hot coffee or an ice cold beverage sometimes cause a painful dental experience for you?  Is it often uncomfortable to brush or floss your teeth?  If so, you may have sensitive teeth.

Tooth sensitivity affects a large number of people. According to the American Dental Association, the most common causes include:

  • Tooth decay (cavities)
  • Worn tooth enamel
  • Exposed tooth root
  • Fractured teeth
  • Worn fillings
  • Gum disease

In healthy teeth, a layer of enamel protects the crowns of your teeth—the part above the gum line. Under the gum line a layer called cementum protects the tooth root. Underneath both the enamel and the cementum is dentin. Dentin is less dense than enamel and cementum and contains microscopic tubules (small hollow tubes or canals). When dentin loses its protective covering of enamel or cementum these tubules allow heat and cold or acidic 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.

Sensitive teeth can be treated. The type of treatment will depend on what is causing the sensitivity. Dr. Moore or Dr. Redmin may suggest one of a variety of treatments:

  • Desensitizing toothpaste. This contains compounds that help block transmission of sensation from the tooth surface to the nerve, and usually requires several applications before the sensitivity is reduced.
  • Fluoride gel. An in-office technique which strengthens tooth enamel and reduces the transmission of sensations.
  • A crown, inlay or bonding. These may be used to correct a flaw or decay that results in sensitivity.
  • Surgical gum graft. If gum tissue has been lost from the root, this will protect the root and reduce sensitivity.
  • Root canal. If sensitivity is severe and persistent and cannot be treated by other means, your dentist may recommend this treatment to eliminate the problem.

Proper oral hygiene is the key to preventing sensitive-tooth pain. Please contact Moore Family Dental if you have any questions about your daily oral hygiene routine or concerns about tooth sensitivity.
