I have corrected my teeth before ~ ~ 12 years old. I once saw my uncle in his thirties and forties correcting his teeth in the clinic.

So it's not too late for you to correct your teeth. But I want to remind you that orthodontics is very hard. In addition to pain, there is psychological pressure. You won't dare to open your mouth and laugh, you will mind your mouth swelling ... so think twice before you prepare yourself mentally. Also, I want to tell you that when you pull out tiger teeth, your smile will become very strange. You should protect it and make up your mind to correct it.
