In case of simple tooth extraction, tooth extraction socket takes 10-14 days to heal completely and in case of surgical tooth extractions, depending on the amount of trauma to the investing supporting tissues, tooth extraction socket may take weeks to months to heal completely. Mild pain which is there will reside in other 3-4 days if they were simple tooth extractions and may take 2-3 weeks to reside completely if they were surgical tooth extractions. Stitches should be at place at least for 5-7 days after tooth extraction. Stitches approximate the flap margins and facilitate the healing of tooth extraction socket. If they are non-resorbable sutures, then you have to get them pulled out from your dentist and if they are resorbable stitches, then they will dissolve on its own. Non-resorbable stitches are to be pulled out 7-10 days after tooth extraction. If there is severe throbbing, radiating pain present along with necrotic bone present at that site, then it can be because of dry socket. If you have these symptoms, then refer to your dentist for evaluation of the socket. You can continue with warm saline rinses and take the meds as prescribed for faster healing to take place. Follow instructions of your oral surgeon and keep the extraction socket area clean to avoid any secondary infections.
