Cut, Puncture, or Tear Inside Your Mouth or on Your Lip
A cut or puncture inside your mouth may bleed a lot, even after a
minor injury, because there are many blood vessels inside of the mouth. You can
usually stop any bleeding if you apply firm pressure with a piece of cotton
gauze for about 15 minutes. Be sure to review
first aid measures to stop bleeding. If first aid does not stop the bleeding,
medical care is required.
A cut, puncture, or tear inside your mouth may
require stitches. Deep cuts are likely to need
stitches and should generally be stitched within 6 to 8 hours after the injury
to reduce the risk of infection. This risk increases the longer the cut remains
untreated. Some cuts may be able to be stitched up to 24 hours later.
