Exposed gums can be caused by maxillary protrusion, short upper lip, or low attachment position of tie, which can be improved by orthognathic treatment or surgical treatment.
1. Anterior protrusion of the upper jaw: when the upper jaw protrudes forward, the front teeth will be covered to a larger extent, and the gums will be exposed when opening the mouth, which affects the aesthetics, and it can be improved by orthognathic treatment, which moves the teeth slowly to the correct position.
2. Upper lip is too short: If the upper lip is short, the gums can not be well wrapped, and the gums will be exposed when you open your mouth, which can be improved by lifting the upper lip muscle fracture treatment.
3. Low attachment position of the ligament: This can also lead to exposed gums, which can be improved by ligament lengthening surgery.
When the gums are exposed, go to the hospital in time to find out the cause and actively treat it.
