Causes of Tooth Sensitivity

Tooth sensitivity, or dentin hypersensitivity, affects about half of the population. This dental condition is a sensitivity to heat, cold, acidic and/or sweet foods that can cause discomfort in the affected tooth or teeth. Some individuals have tooth sensitivity that will periodically occur, and others have this condition mostly all of the time.

Tooth sensitivity can occur when the dentin on root areas of the tooth are exposed. Exposure can be caused by receding gums, which can happen when there is periodontal disease present. Dentin can also be exposed when the teeth are brushed too hard and vigorously or when toothpaste that abrades the teeth is used. Another cause of dentin exposure is a very acidic diet. Acid will erode the enamel of the tooth and, in time, can expose the dentin. Those suffering from bulimia or GERD, a reflux problem, can have sensitivity of the teeth because of acid that is often in the mouth.

Tooth sensitivity should always be checked out by your dentist, as cavities will cause similar pain in response to heat, cold, acidic and/or sweet foods. If tooth sensitivity is the problem, there are a few options. Special toothpaste formulated for sensitive teeth might be recommended. A fluoride rinse or gel that is brushed onto the teeth may also be helpful. Use of toothpastes with high fluoride content might help. Your dentist can also apply a fluoride coating onto your sensitive teeth, and lasers can be used as well. If you have tooth sensitivity, contact Dr. Robert Mondavi, dentist in Torrance, to make sure it is not caused by tooth decay or other dental problems.
