Modern dental theory holds that there is no age limit for orthodontics. That is to say, you can correct it no matter how old you are, but the older you are, the longer it may take to correct it and the greater the possibility of rebound (so you may need to wear a retainer for a longer time after completion).

There are many cases of correction at the age of 37. I have seen several cases, mostly women, and one of them is a man who is almost 50 years old. If you still have this idea, you can consult an orthodontist. Perhaps, it's just a matter of time and cost (the longer the time, the higher the cost).

I wish you more and more beautiful and younger!
