Thanks for the query.
It is normal to have a flap of tissue at the site of tooth extraction. Furthermore it is normal to taste blood following the tooth extraction. So do not worry, it will heal up in few days. Usually the edges of gum will be stitched by the dentist
after extracting the wisdom tooth. Still, loose edge of the tissue remains. This maybe the part you are feeling with your tongue. You will not get any dry socket
from feeling a flap there. But certainly there are few things you can care to prevent dry socket.
- Do not try to repeatedly touch the wound site by your tongue. This can dislodge the clot from the wound.
- If you smoke, try avoiding it.
- Do not rinse your mouth forcefully.
- If you feel there is extra bleeding from the site continuously, please visit your dentist immediately.
Hope I have answered your concerns. let me know if I can assist you further.
