Hello, according to the symptoms you described, under normal circumstances, people have at least 28 teeth, with 14 upper and 14 lower. Maybe you have a congenital missing tooth or an embedded tooth. You can do orthodontics at the age of 28. In fact, there is no age limit for orthodontics, but the older you are, the slower your teeth move and the longer it takes to correct them. Correction requires a fixed appliance, both metal and ceramic. You can decide what to use according to your personal situation.

Suggestion:

Suggestion: It is best to go to the dental department of a regular hospital or a regular dental clinic to get professional treatment for your teeth. Let the doctor see the number of your teeth first, then take a photo to see if there are any embedded teeth, and then make a correction plan according to the specific situation of your teeth.
