Nail Bracing 

Nail braces work by gently lifting the sides of the toenail and eventually retraining the nail to grow to a flatter shape over time.

The total time needed for the nail to be reshaped is one full nail growth or about 18 months. There are two main types of nail braces: adhesive and hooked. The ingrown toenail brace acts like a spring, gently straightening and lifting each side of the toenail, reducing its pressure against the skin. Correction is painless and occurs over a period of weeks. The ingrown toenail brace is intended for the big toe. … A brace that corrects the toenail too quickly will cause pain.
