Whether teeth can be smoothed or not needs to be decided according to the severity of the teeth misalignment. If only individual teeth are misaligned, they can be smoothed, if the teeth are more severely misaligned, smoothing is not recommended. 1. If the patient only has individual teeth that are not aligned, then it can be smoothed and usually will not affect the normal chewing function of the teeth. If the teeth are severely misaligned, it is not recommended to grind them down, because grinding them down may cause damage to the dentin and enamel, and cause tooth pain. 2. For patients with severe teeth misalignment, timely visit to the hospital, can be under the guidance of the doctor for orthodontic treatment, such as invisible orthodontics, bracket orthodontics, etc., can effectively treat teeth misalignment. When the patient has uneven teeth, don’t blindly grind the teeth, should go to the hospital in time, in the doctor’s guidance to choose the suitable treatment method, to avoid the adverse effects.
