I had a tooth extracted 2-3 months ago, the back of my gums has swollen across three of my teeth near the extraction site. is this normal?

Post Op Extractions!: Good day Usually after 4-6 weeks complete healing has occurred. The symptoms you present may be from adjacent teeth. In any event contact your dentist and return for a follow up visit! Or you may seek out Oral surgeon for a second opinion.

No: Swelling is never normal. Return to Dentist or Oral Surgeon who did the extraction for reevaluation. Don't be surprised if referral to a Periodontist is recommended.
