Male, eighteen. My grandfather twisted my tooth when I was a child. Now the upper front teeth are splayed and the lower front teeth are dislocated. I want to repair and correct them.

It can be corrected. Although you are past the best age for correction, if you decide to correct it, I suggest you go to a local regular hospital for correction. Let the doctor examine you carefully before correction and make a specific correction plan. It will take about a year and a half.
