It depends on the specific situation. If it is a small seam, it does not affect the appearance, so there is no need for cosmetic surgery.

If the seam is too big, you should go to the hospital for examination. The doctor should advise you to have plastic surgery. Tooth shaping is generally suitable for 14~ 17. It will last a long time when you are old, and it will also have an impact when your teeth are not long enough when you are young.

I suggest you go to the hospital for a checkup.
