Teeth consist of several layers of tissue. The most external, the enamel, is the hardest and the one responsible for protecting the teeth. Inside is dentin, which contains thousands of nerve endings that are responsible for sensitivity.
When a dentine is exposed, external stimuli can reach it and travel through tiny channels, causing a sharp, short-lived blink, which is known as tooth sensitivity.
The causes of tooth sensitivity can be very diverse depending on the degree and circumstances of each person. Among them are two main reasons why it usually appears:
Enamel wear, either over time, by sudden brushing or the action of acidic foods and drinks.
Gum recession, leaving the base of the teeth exposed as the enamel does not cover the two dentines.
How do I know if I have sensitive teeth?
Not many people know how to easily detect the symptoms of tooth sensitivity. Especially when these are weaker or starting off, it can be difficult to recognize sensitivity in the teeth.
Allergy symptoms that most allergy sufferers usually describe are as follows:
Stabbing pain on a mild stimulus.
Very short duration of pain prior to the stimulus in question.
The immediate location of the area where the pain is noticeable.
If you usually notice very severe pain in the same area of the mouth whenever you take some cold, hot and very acidic food in certain circumstances, then it is time to act and strengthen your teeth in the face of tooth sensitivity.
