Oral surgery gum-tissue flaps.
With some surgical extractions, it will be necessary for the dentist to create a gum-tissue flap.
The idea of a flap is that when it is reflected (pealed back), it allows the dentist access to both the tooth and bone tissue that surrounds it.
After the tooth has been removed, the flap is then returned to its original position and stitched back into place.
How are the tissue flaps created for oral surgery made?
Here's how a dentist "lays" a flap when performing a surgical tooth extraction.
1) They first use a local anesthetic (give you a "shot") so to numb up your tooth and its surrounding tissues.
2) They'll then use a scalpel to score the outline of the flap, cutting directly through the gum tissue down to the bone.
(Since you're numb, you won't feel any pain. You will, however, feel the pressure of the scalpel.)
3) Once the flap's outline has been scored, the dentist will reflect it back (peal it back from the bone).
