### What is Tooth Resorption? Tooth resorption happens when parts of a tooth start to break down and are absorbed by the body. This can be caused by injuries, teeth grinding, or cavities. It's important to see a dentist for treatment because there are several procedures that can help save the tooth. ### Types of Tooth Resorption Tooth resorption can be classified into two types: internal and external. - **Internal Resorption**: This affects the inside of the tooth and is less common. It often occurs in people who have had extensive dental surgery. Dentists usually detect it through X-rays. - **External Resorption**: This is more common and affects the outer surface of the tooth. It can be seen as deep holes or chips on the outside of the tooth. ### Symptoms Symptoms of tooth resorption can be hard to notice at first. As the condition worsens, you may see swelling in your gums, pink or dark spots on your teeth, or changes in the spacing between your teeth. ### Causes Several factors can cause tooth resorption: - **Injuries**: Trauma to the mouth or teeth can lead to resorption. - **Orthodontic Appliances**: Prolonged use of braces can cause resorption. - **Teeth Grinding**: This can wear down the teeth and lead to resorption. - **Cavities**: Untreated cavities can cause internal resorption. ### Diagnosis Dentists diagnose tooth resorption through physical exams and X-rays. They may ask about your dental history to identify any past injuries or procedures that could have affected the tooth. ### Treatment Treatment focuses on preserving the remaining parts of the tooth. This usually involves removing the damaged parts to prevent further resorption. In some cases, implants or veneers may be used to replace the affected teeth. ### Prevention Regular dental check-ups are the best way to prevent tooth resorption. Dentists can catch early signs and provide treatment to stop the condition from worsening.
