Could you tell me what's the best treatment of ingrown toenails?

Ingrown: My best suggestion is have a portion of the nail removed under local. Very simple and done in office.

Removal...: ...Is the only permanent solution. Just the painful border can be removed, or the entire nail if necessary. After removal you can let the border grow out again, or your doctor can use a chemical to stop the nail from regrowing. If you're concerned, don't perform bathroom surgery on yourself. That can lead to an infected ingrown toenail, which could require antibiotics.
