What is Tooth Sensitivity?

Dentin hypersensitivity or root sensitivity is popularly known as tooth sensitivity. When hot, cold, sweet or very acidic foods or beverages are consumed the tooth sensitivity occurs.

Is it Common?

Tooth sensitivity is a common problem and approximately half of the population experiences it. The sensitivity can come and go time-to-time.

What are the Causes?   

There are several causes that lead to tooth sensitivity. These causes include:

Brushing too Much Gusto

At times the tooth sensitivity is caused by brushing with too much force or with too hard bristles. Eventually, the protective layers of teeth will wear down and the microscopic hollow tubes or canals will be exposed that will lead to your dental nerves. When these tubules are exposed to hot or cold to acidic or sticky foods, tooth sensitivity and discomfort may be caused.

Eating Acidic Foods

When the pathways become exposed, the acidic foods like tomato sauce, lemon, grapefruit, kiwi and pickles can cause pain.

Tooth Grinding

If you grind your teeth regularly, the enamel breaks down even though it is the strongest substance in the body. Grinding teeth can expose the dentin which contains the hollow tubes that lead to the nerves.

Tooth-whitening Toothpaste

Chemicals found in the tooth-whitening toothpaste can make your tooth sensitive more than normal toothpastes.

Gum Disease

With age the gums start receding which can cause tooth sensitivity. When you suffer from gum disease or gingivitis, a procedure may be needed to seat the teeth.
