This depends on a person’s general, post-operative care, size and location of the tooth.
Simple tooth extraction If your tooth has fully erupted, the wound from your tooth extraction should heal within 7 to 10 days. The gums will usually fully close in about 3-4 weeks after the tooth was extracted and the bone will regrow in around 3 months.
Surgical extraction If your tooth is within the gums (not fully erupted or is badly broken down), recovery will take a little longer. The healing will range from a week to 3 weeks and it will take about 8 weeks for the hole to close fully. Avoid heaving brushing, flossing, or chewing near the treatment area during the first few days.
