If your concern is only about the hole that you can see, then it will get healed eventually. Complete epithelium healing takes about a months time. Till then you can massage your gums at the extracted area with hexigel
, metroplex etc. If there is pain
or discomfort you need to get it checked for any infection/inflammation in that area. Mouthwash use avoids infections/ inflammation in the area and helps fasten healing. Hope this helps.
