treating someone in their early 20s would not be a problem for an orthodontist. the goal for orthodontics is to straighten teeth in order to make them easier to clean and to make them function in the ways that they’re supposed to. teeth function better when they are straight up and down and not at an angle. it sounds to me like your dentist has only your best intentions in mind.
i am 23 years old and my dentist said that i need braces for my top teeth. is this a good idea?
