One of the most common concerns that the dentist receives in his or her oral health consultations is dental hypersensitivity. Even from people who apparently do not have caries or serious dental conditions, nor do they suffer or have ever suffered from dental hypersensitivity. It is a problem of the dentin that is overstimulated when exposed, usually to cold or heat. Dentin is the softer area of the tooth below the enamel. In addition to hot or cold food, any other stimulus can also cause pain, such as brushing or simply lightly touching the damaged tooth.
Why it occurs and how to solve dental hypersensitivity.
The dentin or dental pulp is composed of fibers and many nerves. When the fibers become inflamed, pain is triggered which, at times, can become unbearable. Blocking the open tubules that allow contact with the agent causing the stimulus can prevent the dentin fibers from swelling, as a defensive reaction, and end the problem.
The pain will disappear when the irritation of the nerves and pulp disappears. For this, the dentist can block the open tubules. Although sometimes the pain does not resolve. Therefore, it is necessary for the dentist to analyze and assess the most appropriate treatment.
Often, it is wear due to decay or poor brushing that is behind the throbbing pain of dental hypersensitivity. Specific treatment, such as a filling to seal the tooth, may therefore be necessary. In more severe cases, even endodontics, i.e. «killing the nerve», becomes essential. Although in general, in mild cases, the application of rinses, gels or toothpastes and the corresponding periodic check-ups are usually sufficient to ensure that good oral health is maintained.
