Detailed Answer:
Hi

Thanks for posting the query and image

I understand your problem and would try my best to help you.

1. The recurrent abscess formation at a particular point could be due to various causes. This could often mislead the practitioners.
2. The commonest causes include:
a. Cutaneous odontogenic fistulae (a through and through track from an infected tooth to the skin)
b. Sinus tract (infected material adjacent to the tooth opening up into the skin)
c. Actinomycosis of the mandible
d. Osteomyelitis of the mandible
3. We need to do the following investigations to identify the cause:
a. Culture of the abscess
b. Orthopantogram of the mandible or CT scan of the jaw to identify the actual cause of the problem
4. The best person who can help you is a maxillo-facial surgeon for the further investigations and management

Hope this answers your query; revert back to me if you have any follow up queries.
