Dentinitis is a dental condition characterized by inflammation or irritation of the dentin, which is the hard, calcified tissue that forms the bulk of a tooth. Dentin is usually protected by the outer layer of enamel or cementum, but when it becomes exposed or affected by various factors, it can lead to dentinitis.
The most common cause of dentinitis is tooth decay or dental caries, where the bacteria in the mouth produce acids that erode the tooth enamel, eventually reaching the dentin. As a result, the dentin becomes hypersensitive and painful when exposed to hot or cold foods or drinks.
Other potential causes of dentinitis include gum recession, which exposes the tooth root, excessive tooth brushing or use of abrasive toothpaste that wears away the protective layers of the tooth, and tooth trauma such as cracks or fractures that expose the dentin.
Symptoms of dentinitis include tooth sensitivity, especially to temperature changes, pain while chewing, and discoloration of the affected tooth. If left untreated, dentinitis can progress to more severe dental problems such as tooth abscess or infection.
Treatment for dentinitis typically involves identifying and addressing the underlying cause, such as treating tooth decay or gum recession. Dentists may recommend desensitizing toothpaste or mouth rinses, fluoride treatments, dental sealants, or in more severe cases, dental procedures like root canal treatment.
Regular dental check-ups, good oral hygiene practices, and a healthy diet can help prevent dentinitis and maintain overall oral health.
