Hello, your teeth can be adjusted. If your teeth are sparse or irregular, these can be remolded. However, it still varies from person to person if you want to do dental plastic surgery that suits you according to your personal situation. I suggest you go to a good specialist hospital for a routine dental examination, so that you can know what kind of plastic surgery is suitable, and it takes time and money. Orthodontics is to treat malocclusion through orthodontics or surgery. Generally speaking, girls are best corrected at the age of 10- 12, while boys are best corrected at the age of 1 1- 13. At this time, the deciduous teeth have just been changed. But the general elderly can also do orthodontics, and you can do it according to your own situation and age. I suggest you go to the orthodontics department of your local hospital for consultation.
