Sensitive teeth
Studies show that about 40% of the population (in the areas studied) suffers from sensitive teeth. Usually tooth sensitivity (dentin hypersensitivity) manifests itself as temporary tooth discomfort or pain after eating cold food, drinking cold liquids, or breathing cold air.
The most common cause of sensitive teeth is when the gums which protect the teeth recede. When this happens the underlying tooth roots are exposed. These roots contain small pores (tubules) which lead directly to the nerve of the tooth. As a result pain, pressure, and hot and cold stimuli can travel down the tubules triggering the nerve.
Gums commonly recede for two reasons:
- Poor oral hygiene. This leads to a build-up of plaque around the teeth and gums which in time hardens into tartar. Bacteria in the tartar are responsible for the gingivitis and periodontal disease that causes gum recession.
- Incorrect brushing of the teeth. A surprising number of people brush their teeth with too much pressure. Over time this brushing removes gum tissue exposing the tubules.
