Why Teeth Become Sensitive

why teeth become sensitiveEating should not hurt, but if you have sensitive teeth, something as simple as an ice cream cone or a hot coffee could have you gasping in pain. Tooth sensitivity affects about half the population at least occasionally and can occur as a result of several issues, including:

• Gum recession
Gum recession is often due to periodontal disease and can leave the roots exposed. Since roots do not have a protective layer of enamel, they are more likely to become sensitive and can even be more vulnerable to decay.

• Aggressive brushing habits
Using a hard-bristled toothbrush, abrasive whitening toothpastes, or simply brushing too hard can all erode enamel or irritate gums, leading to sensitivity.

• Acid erosion
A diet high in acidic foods and drinks, GERD, and bulimia are common causes of acid erosion, which wears away the enamel and exposes dentin.

• Untreated dental disease
Tooth decay, infection, cracks, and gum disease can cause pain after sweet, acidic, hot, and cold foods and drinks.

Unlike enamel, dentin, or the inner layer of the teeth, contains channels that run through the dentin and to the nerve inside the tooth. Each channel contains fluid that flows when it comes in contact with hot or cold temperatures, and this irritates the pulp of the tooth. The best way to prevent tooth sensitivity is by maintaining a healthy, balanced diet and brushing properly with fluoride toothpaste and soft-bristled brush to protect the enamel coating on your teeth.
