While out with friends one evening, you take a bite of ice cream. Suddenly, pain shoots through your teeth. It only lasts a second, but it's enough to ruin your good time.
This could be tooth sensitivity, a painful reaction to hot or cold foods. It often occurs when the enamel in prolonged contact with acid has eroded. Acid is a waste product of bacteria found in plaque, a thin film of food particles that builds up on tooth surfaces due to inadequate brushing and flossing. Enamel normally mutes temperature or pressure sensation to the underlying dentin layer and nerves. Loss of enamel exposes the dentin and nerves to the full brunt of these sensations.
Sensitivity can also happen if your gums have shrunk back (receded) and exposed dentin below the enamel. Although over-aggressive brushing can often cause it, gum recession also happens because of periodontal (gum) disease, a bacterial infection also arising from plaque.
The best way to avoid tooth sensitivity is to prevent enamel erosion or gum recession in the first place. Removing accumulated plaque through daily brushing and flossing is perhaps the most essential part of prevention, along with a nutritious diet low in sugar and regular dental cleanings and checkups.
It's also important to treat any dental disease that does occur despite your best hygiene efforts. Gum disease requires aggressive plaque removal, especially around the roots. While receded gum tissues often rebound after treatment, you may need gum grafting surgery to restore lost tissues if the gums have receded more deeply. For enamel erosion and any resulting decay you may need a filling, root canal treatment or a crown, depending on the depth and volume of structural damage.
While you're being treated you can also gain some relief from ongoing sensitivity by using a toothpaste with potassium nitrate or similar products designed to desensitize the dentin. Fluoride, a known enamel strengthener, has also been shown to reduce sensitivity. We can apply topical fluoride directly to tooth surfaces in the form of gels or varnishes.

Tooth sensitivity is an issue that can range from a slight twinge at times to downright excruciating pain. However, before we continue, understanding the cause of tooth sensitivity is helpful to both relieving and treating it.
Tooth enamel is inert in that it has no nerve supply and thus it protects the teeth from temperature and pressure changes — the main cause of sensitivity. Once it is compromised, worn thin, or exposed due to gum recession, it leaves the delicate nerve fibers within the dentin vulnerable to touch, acid, and temperature change. These nerve fibers most often grab your attention when they come in contact with heat, cold, or a “double whammy” combination of both cold and sweet. They also become sensitive to touch — even the bristles of a soft toothbrush can irritate exposed dentin.
As for the causes of tooth sensitivity, one common cause we see is aggressive brushing. Yes, too much brushing can be bad for you! To be more specific, excessive, improper brushing with a sawing back and forth motion can erode the gum tissues, expose, wear, and even groove the dentin. Another cause for sensitivity can be from the destructive process of tooth decay that eats through the enamel and into the dentin.
