[|Human|] I had my front upper teeth filled yesterday, and my lip is still swollen after 15 hours.  I also developed a huge water blister during the time they were working on my teeth.  The blister has gotten bigger and it is really hard to smile, eat, and talk.  I have rinsed the area with half hydrogen peroxide & half water and noticed some swelling go down but not completely. I also took ibprofin for the pain. I have been using cold compresses as well.  Is there anything else that I can do?
[|AI|]  Hi! Welcome to Chat Doctor. I read your query. Water blisters can happen due to various reasons like stress, infection, trauma, etc. In your case, its trauma related, probably. It can either be due to trauma during filling or overhung filling causing friction and thus blisters. In second case, you need to get your filling corrected. Otherwise, no treatment is required for blisters. Regarding lip swelling, it can be due to allergy or trauma. Do warm compressions, warm saline rinses. Take Ibuprofen or Tylenol for pain. If it persists even after 2-3, you need to get your filling checked. Hope the answer helps you. Thank you.
