Proper oral hygiene is an important step in preventing tooth decay, periodontal disease and pain from sensitive teeth. If you brush your teeth incorrectly or brush too aggressively, you may injure your gums and expose tooth roots.
Periodontal disease-an infection of the gums and bone that support the teeth-also may be responsible. If periodontal disease is left untreated, gum tissues can separate from the teeth and form spaces called pockets that provide a home for bacteria. Periodontal disease can progress until the bone and other tooth-supporting tissues are destroyed, leaving the root surfaces of teeth exposed. Regular dental checkups are important so that tooth decay, periodontal disease and other problems may be detected and treated in the early stages.
Sensitive teeth can be treated. Depending on the cause, your dentist may suggest that you try desensitizing toothpaste, which contains compounds that help block sensation traveling from the tooth surface to the nerve. Desensitizing toothpaste usually requires several applications before the sensitivity is reduced. When choosing toothpaste or any other dental care products, look for those that display the American Dental Association's Seal of Acceptance-your assurance that products have met ADA criteria for safety and effectiveness.
If the desensitizing toothpaste does not ease your discomfort, your dentist may suggest in-office treatments. A fluoride gel or special desensitizing agents may be applied to the sensitive areas of the affected teeth. When these measures do not correct the problem, your dentist may recommend other treatments, such as a filling, a crown, an inlay or bonding to correct a flaw or decay that results in sensitivity. The type of treatment will depend on what is causing the sensitivity.
If gum tissue has been lost from the root (gum recession), your dentist may recommend a surgical gum graft to cover the root, protect the tooth and reduce the sensitivity. In cases in which hypersensitivity is severe and persistent and cannot be treated by other means, your dentist may recommend endodontic (root canal) treatment to eliminate the problem.
