Precautions after orthodontics:

1, maintain oral hygiene.

Be sure to wear braces when orthodontics, otherwise it will affect eating. Every time you finish eating, there will be food residues left in your teeth, so be sure to keep your mouth clean, brush your teeth in the morning and evening, and try to choose a special toothbrush.

Choose the correct brushing method. After orthodontics, you need to wear the retainer of 1~2 years, and wear it in strict accordance with the doctor's advice. Never take it off yourself, or it will rebound.
