When a tooth exposes its roots, the first thing to consider is to visit a nearby dentist or dental clinic as soon as possible to check the specific situation. One of the more common clinical conditions that expose the roots of the teeth is occlusal trauma, which is caused by an excessive high point gap in the teeth, thus causing a relatively large load on the teeth and thus exposing the roots of the teeth. This type of condition can improve its symptoms through accommodation, that is, grinding out the corresponding high points. It can also be seen in the recession of teeth due to trauma when brushing or eating, in which case it is important to maintain good oral hygiene, contain mouthwash and replace the toothbrush. Do not touch the trauma again, and it will usually heal in about 5 days. However, the most clinically seen situation that exposes the roots of the teeth is generally referred to periodontitis, which refers to the situation where the roots of the teeth are exposed and the teeth are loosened due to gum recession, and then it is necessary to go to the dentist for systematic periodontal treatment, including scaling and subgingival scaling, and then protect the roots of the teeth from excessive exposure as much as possible.
