Hello mam... Mild   Swelling after tooth extraction is normal.....sometimes it may be due to hematoma during posterior superior alveolar nerve block......Apply ice pack in that swelling area intermitently 5 minutes with 20 min interval....Have the analgesics and antibiotics as prescribed.....it ll resolve gradually....if the seeking persits even after 10 days then visit dentist for further clinical examination

Post extraction the swelling is normal. Continue with your medications as prescribed by your dentist along with warm saline mouth rinse and betadine mouth rinse after meal. But if it still continues consult your dentist.

How many days back did u get the extraction done? Some swelling is normal post extraction.

If the extraction is recent then don't worry it will be ok in few days and if the extraction is old then pls visit  ur dentist and get the X-ray done
