Hello: During the plastic surgery, the teeth will loosen slightly when forced to move, but after a period of maintenance after orthodontic treatment, the alveolar bone around the teeth will be rebuilt and the teeth will become as stable as before. Guidance: Keep teeth clean and sanitary, and try to avoid water accumulation in the operation area within 7 days after operation. Avoid eating irritating foods, such as peppers. Strictly follow the doctor's advice and make follow-up visits.
