Note: 1. Pay attention to oral hygiene: when wearing movable or fixed appliances, you should maintain oral hygiene, especially fixed appliances, because the appliances are stuck to the teeth and you can't take them off to brush your teeth. Food residues are easily left around the appliances, resulting in a large number of bacteria, which is easy to form dental caries and tooth heel inflammation. So you should get into the habit of brushing your teeth for not less than 5 minutes after meals, and adopt the method of alternating horizontally and vertically.
2. Don't eat hard food or sticky food during orthodontic treatment.
3. Regular follow-up: Orthodontic treatment needs constant adjustment, so it needs constant follow-up.
