What is tooth sensibility and what are the causes for this condition?

Posted By: Varun Sharma

Tooth sensibility is a common name used for Dentin Hypersensitivity or Root Sensitivity.  According to the AGD (Academy of General Dentistry), more than 45 million Americans are suffering or experiencing tooth sensitivity. This condition is characterized by a tingly feeling or a little flash pinch of pain in a particular area of the tooth or to all the teeth. This condition may not affect a person all the time, but intermittently. This intermittent tooth sensitivity is occurring when the temperature around the teeth changes, especially when in contact with cold or hot foods or beverages and when cold air directly hits the teeth. Because of the pain, most people mistaken the tooth sensitivity pain with root damage. 

Why does Dentin Hypersensitivity happen?tooth sensibility

 This sensitivity condition is caused usually by the dentin located on the root areas that are overexposed due to receded gums or even periodontal disease. Today you will encounter the presence of receded gums in more than 80 percent of the people by the time they reach the age of 65.

The overexposed area that is showing as the result of receded gums or periodontal disease does not have enamel. Usually, all the area that is showing in a 100% healthy tooth has an enamel layer that is protecting the tooth. The newly exposed area is instead covered by a very soft layer which is called cementum. This cementum can be quickly lost which will result in a dentin exposure of the root.

Also, you can lose the tooth’s enamel layer and exposing the dentin with an overzealous brushing style or by using a very abrasive toothpaste. Another thing you need do is pay attention to a very acidic diet like citrus foods, pickles, and soda pops. These type of foods can result in a tooth erosion and the tooth surface dissolvent. People who are bulimic are suffering from dental decay and sensitivity due to the acid that exists in the stomach and is present in the mouth in higher levels than normal.

Treatment and prevention

It is important to tell your hygienist or dentist if you have sensitive teeth. This way they will examine your mouth and can establish the root of your sensitive problem. In addition, they will be able to give you a proper treatment especially for you. When you suffer from this tooth sensitivity, you can even find the brushing of the teeth painful. It is a vicious circle. You suffer from tooth sensitivity, which gives you pain when brushing your teeth and if you do not brush your teeth properly, the sensitivity can last for a longer period and increase the risk of tooth decay and gum disease.

The best way of treating this sensitivity is through a careful prevention so that the sensitivity never happens. And the only way of preventing dental hypersensitivity is through a healthy diet. The teeth’s health is directly connected with the overall health of the body. Teeth change their composition alongside with the body’s vitamins and minerals. For example, if you lack calcium, the teeth will also lack calcium and will present a greater risk of damage and cavities. So if you keep yourself healthy, eating fruits and vegetables, and will not eat fast foods and beverages full of sugars your teeth will be healthier. Also do not forget to brush at least two times a day.
