What is Tooth Sensitivity And Exposed Dentin?

Quite often, we come across the term 'sensitive teeth' while talking about oral health care. Not only this but the advancement in dental technology has also enabled several companies to introduce oral care solutions catering specifically to sensitive teeth. But what is tooth sensitivity?

Tooth sensitivity refers to the sharp pain or discomfort that one feels after eating something hot or cold. This temporary pain can affect either one tooth, a couple, or all the teeth in the mouth and the intensity of the pain or discomfort also varies from individual to individual.

What is Exposed Dentin?

Dentin is the part of the tooth beneath the enamel and cementum of the tooth. When the enamel is worn down due to several factors, the dentin of the tooth gets exposed. Thus, one may experience sharp pain or a feeling of discomfort in their tooth when it comes in contact with any hot, cold, or acidic substance. 

Now that we know what is tooth sensitivity and exposed dentin, it is also important to know what causes the same.

Our tooth is protected by an outer layer known as the enamel. Some individuals have thinner enamel, leading to more sensitive teeth than others. However, there are several other reasons that may lead to the enamel of the teeth getting worn out. Here are the following:

Brushing too hard: One must brush their teeth and gums gently for two minutes using a soft-bristled toothbrush. Brushing too hard can lead to tooth abrasion and can also wear down the enamel of the tooth.

Grinding your teeth: Bruxism or teeth grinding can lead to the enamel getting worn out over time, thus exposing the dentin of the tooth.

Acidic Food & Beverages: Regular consumption of acidic food and beverages can also lead to enamel erosion. This can eventually cause sensitivity in the teeth.

Tooth decay: Plaque buildup and decay are also major causes of sensitive teeth. This is because the bacteria in the plaque can damage the enamel, thus exposing the dentin underneath.

Apart from this, there can be several other factors which include hormonal changes, other underlying health concerns, age, and more that can cause sensitive teeth. It is essential to maintain proper oral care and visit your dental professional to attain the best treatment suitable for you.

Treatment for Sensitive Teeth & Exposed Dentin:

The treatment for sensitive teeth and exposed dentin will vary from individual to individual depending on various factors. Your dental professional will be able to guide you regarding the appropriate treatment option as per your oral health. 

Apart from this, it is essential to maintain proper oral hygiene with the use of an automatic toothbrush and water flosser®. Use an automatic toothbrush with soft bristles to thoroughly clean every corner of the mouth. It is also very essential to keep a check on your diet and avoid the excess consumption of food that is highly acidic. One must also implement certain lifestyle changes and avoid the consumption of tobacco-based products.
