I'm also an orthodontist ~ Look at your son, he may be in pain during orthodontics. You do ideological work for your son first, and his son must listen to the doctor and insist. If your son doesn't insist, it won't have any effect! I can only tell you the basics of correction, not too much! After all, I am not an expert! Just use it for reference! He stuck a square nail on each tooth with a special glue, and then stuck it in the seam of each nail with an arch wire (the arch wire is in the shape of a normal tooth arc and has a fixed shape), and then fixed it with a thinner, shorter and softer wire, and then slowly exerted force over time! ! ! ! ! ! ! It will be very uncomfortable! And there will be restrictions on eating! Hard to eat, you'll knock the nail off! After the nail is pushed off, it is not only troublesome but also affects the correction effect and prolongs the correction time! In short, the journey is very difficult! ! Correct it, there is no problem now, it depends on your son's insistence! If you want your son to have beautiful teeth, you must make him insist! I insist on it very well. It only took two years. Before, my teeth were similar to your son's. Now they look much better! The effect is very good! Remember to stick to it! It is best to correct after changing your teeth! It will be awkward and uncomfortable at first! Remember, cook anything soft! !
