Wound Advice After Your Oral
Biopsy - Information For Patients
A biopsy is the taking of a small piece of tissue for
microscopic examination usually carried out after a
local anæsthetic injection in the area, such as used
for fillings.

The biopsy procedure is virtually painless, though when the
local anæsthetic injection wears off after a couple of
hours, a little soreness will be experienced.

Stitches (
sutures) or a dressing may / may not be used.

Stitches (
sutures) may be resorbable or need to be
removed in the next week (you will be told what type of
stitches you’ve had placed).  It is usually not a problem if
the dressing is lost or the stitches come out earlier than

Rarely there may be

  • altered sensation
  • restricted mouth opening

You will be given a swab to bite on for 10 - 15 minutes if there is bleeding but, if

numbness recovers.
