Teeth are generally not recommended to be polished and trimmed, if a sharp cusp or marginal ridge is formed, then it can be tuned and ground. If it is not in harmony with the neighboring teeth and affects the aesthetics, restorative treatment is recommended. 1. If it is the surface of normal teeth, try not to polish and trim, because after polishing may make the original smooth enamel surface become rough, so that plaque is easy to adhere to, in addition may also cause tooth sensitivity. 2. If the teeth have sharp cusps or marginal ridges due to long-term abrasion, the sharp parts of the teeth can be slightly polished to make them round and blunt, so that they will no longer stimulate the oral mucosa and cause traumatic ulcers. 3. If it is incompatible with the neighboring teeth and affects the aesthetics, restorative treatment is recommended. Specific advice to consult a professional doctor.
