Desensitizing medications are applied by dentists and seal the exposed microscopic pores in the dentin layer of teeth that cause sensitivity.
Desensitizing medications are applied to sensitive teeth by the dentist. It is dispensed from a small bottle and applied with a fine brush.
If a patient is experiencing more than a mild sensitivity to temperature extremes or sweets, and the dentist has ruled out pulpitis (inflamed tooth pulp), tooth decay (caries), infection, or gum disease as a cause, desensitizing medications may be used to seal the microscopic pores of exposed root surfaces.
Desensitizing medications are also frequently used on freshly cut dentin during restorative dental procedures (for example fillings or crowns) before the restoration is placed on the tooth to help prevent later tooth sensitivity. The patient’s tooth is typically numb for such procedures.
