Read your query. The symptoms you have mentioned in the query, suggests the non-healing of the tooth socket and also there is a formation of abscess which is causing you the pain and difficulty in opening the mouth. I would advise you to visit your dentist so that he will have a look at it and if there is an abscess he can do the required treatment to induce the healing of the socket.Additionally, you will require antibiotic like amoxicillin three times a day and metro tablets, ibuprofen if you are not allergic to any medication. Warm saline gargling will be of major help to you. Maintain a good oral hygiene and avoid vigorous gargling. Hope this was helpful. Thanks and regards.
