One of the most common oral diseases is sensitive teeth. This can be very annoying, as it causes a lot of pain, and it is often very difficult to consume certain foods and drinks. Therefore, it is very important to treat this problem in time to enjoy good dental health. Here are the causes of sensitive teeth.
In general, high tooth sensitivity is caused by the gradual exposure of the dentin, the soft part beneath the tooth enamel. The enamel has many tiny tubes inside, which contain nerve endings filled with fluid. When exposed to heat or cold, the fluid travels through the dentin tubes and causes discomfort or pain.
Brushing teeth too hard
Many people believe that brushing their teeth with force, brushing multiple times a day, or using a hard-bristled toothbrush ensures thorough cleaning and good dental health. However, this is not the case. On the contrary, dentists recommend avoiding these practices, as they wear down the enamel and expose the dentin. These habits can also cause gum recession.
Bruxism
Due to stress or tension, some people often sleep while clenching their jaws, resulting in teeth grinding (bruxism). In many cases, this occurs unconsciously, so the person doesn't realize they are doing it. Of course, teeth grinding increases the likelihood of tooth sensitivity. It gradually wears down the enamel and exposes the dentin.
Gingivitis
Gingivitis is a disease that destroys the supporting tissues of the teeth (such as the gums, periodontal ligaments, and dental alveoli) due to an infection and inflammation of the teeth. When the gums become inflamed, the root of the tooth is exposed, which can affect tooth sensitivity. If any symptoms of gingivitis appear, it is recommended to treat it in time to avoid further issues.
Gum recession
Gum recession is characterized by the shrinkage of the gums, exposing the dentin. This problem can be caused by an infection (such as gingivitis) or even by poor oral hygiene practices, such as brushing too hard or using a very hard-bristled toothbrush. Before the first signs of gum recession appear, preventive measures should be taken to avoid tooth sensitivity.
Age
Age can also be a cause of tooth sensitivity. Over the years, tooth enamel is lost as part of a natural cycle. As a result, the dentin is exposed in some cases, leading to high sensitivity. In these cases, there are treatments to reduce discomfort.
