I had a tooth extracted and some stitches fell out today, there is since a small bubble of gum hanging down. i wanted to know if it's normal.

Stitches: Stitches ususally come out 7-10 days after the extraction. So depending on how long ago you had your extraction this may be normal healing. If you are having swelling, severe pain or any concerns call the dentist or oral surgeon and they can answer your question and tell you if you are healing normally.

Yes: This is normal. Should heal in a week if still there see your dentist.

Normal but: If it persist and did not heal within two weeks , see your dentist.
