Hello, the treated teeth will not affect eating. Adults can also correct orthodontics now, which usually takes about 2 years. They can wear ceramic transparent lock grooves, which are similar in color to teeth and not obvious, but more expensive. Orthodontic treatment is painless, but it will be uncomfortable about 2 days after each visit, so there is no need to take any painkillers. The crowded dentition is due to the lack of jaws, so it is difficult to arrange a normal number of teeth. If there are not enough seats in the dentition, orthodontic treatment should be carried out after meiosis extraction.
