What Causes Tooth Sensitivity?

The loss of enamel is usually the reason why people experience tooth sensitivity. When the enamel is lost, the dentin layer of the tooth becomes exposed. The dentin contains microscopic tubular structures that connect to the nerve tissue in the pulp, and external stimuli can travel through these tubules and reach the nerve. External stimuli such as heat and cold, pressure, or sweet and sour foods and drinks can cause your teeth to become sensitive. Tooth sensitivity can run the gamut from mild discomfort to sharp pain.

Many times the reason the enamel has been worn away to the point that the dentin has become exposed is due to the way a person brushes their teeth. If they brush too hard or use a hard-bristled brush, it can wear the enamel away over time. Acidic foods, such as citrus fruits, can also wear away the enamel. For patients that experience gum recession, this can expose the tooth root to external stimuli, which can also be a reason for experiencing sensitivity.

It is important to be able to distinguish between tooth sensitivity and other reasons for tooth pain. Cavities, bruxism, chipped or cracked teeth, and tooth bleaching treatments can all cause pain in the mouth that may be mistaken for sensitivity.
