There are generally two methods of tooth shaping: porcelain teeth and orthodontics.
1, porcelain teeth: for one or two crooked teeth or tetracycline teeth, dental fluorosis and teeth that are difficult to correct. 1 -2 weeks can have a neat and beautiful tooth, but the porcelain teeth need to be polished a little, and then put on the porcelain crown.
2. Orthodontics: The best age for orthodontics is 13- 18 years old, and your age belongs to adult orthodontics, and correction usually takes one to two years. According to your description, if the gap between the front teeth is a little big and all the other teeth are neat, it may not be necessary to extract teeth, hehe-but I suggest you go to a professional stomatological hospital and ask the orthodontist to see if it is necessary to extract teeth.
Finally, I wish you good dental health and sunshine every day. (*^__^*)
