There are numerous reasons for the external surfaces of the teeth to become sensitive to hot, cold, or touch.
Some reasons for sensitive teeth are:
- Gums recede exposing the dentin, which has tiny nerve fibers in it.
- The teeth are repeatedly exposed to acid regurgitated from the stomach, attributed to conditions such as GERD (Gastroesophageal reflux disease).
- The teeth are exposed to acid from continual vomiting (bulimia).
- Aggressive tooth brushing over many years has worn slots in the surface of the teeth, exposing the dentin.
- Excessive eating of acidic foods such as pineapple and tomatoes.
- Excessive drinking of acidic carbonated soft drinks or fruit juices.
- Any other excessive and constant use of acidic foods or beverages.
- The teeth have been worn on their chewing (occlusal) surfaces by bruxism (grinding of the upper and lower teeth together and wearing the enamel off).
Teeth with sensitive external surfaces can be treated several ways, including:
- Using a desensitized toothpaste or other medications.
- Placing a coating of plastic material over the sensitive areas.
- Impregnating the tiny holes (dental canals) in the tooth with various chemicals to desensitize.
- Reduction or elimination of the offending reasons stated above that have caused the sensitivity.
- Placing restorations (fillings) in the sensitive teeth.
Depending on your treatment needs, we will advise you of the best alternative for your sensitive teeth.
Desensitization Treatment - PerioLase MVP-7 Dental Laser
Dental sensitivity affects more than 40% of adults worldwide, and more than 40 million people in the United States.  Exposed dental tubules are believed to be the predominate cause, with sensitivity to heat and cold the most common complaint. Laser therapy can help close tubules and reduces sensitivity.
