The roots of the teeth are exposed because of receding gums, which may be related to periodontitis, improper brushing methods, orthodontic forces and bite forces.
1. Periodontitis: Periodontal inflammation can lead to resorption of the alveolar bone, and the gums attached to the alveolar bone will also recede.
2. Improper brushing method: sawing horizontal brushing method, excessive force, etc.
3. Orthodontic force and occlusal force: when teeth are subjected to excessive occlusal force, or when orthodontic treatment moves the teeth toward the lips and cheeks, recession of the gums often tends to occur.
The root of the teeth alone can not accurately determine the cause, but also need to be combined with the characteristics of the medical history, other test results to make an accurate judgment, it is recommended to clarify the cause under the guidance of the doctor.
