A gum biopsy is a surgery in which a small piece of gingival (gum) tissue is removed for examination.
A painkiller is sprayed into the mouth in the area of the abnormal gum tissue. You may also have an injection of numbing medicine. A small piece of gum tissue is removed and checked for problems in the lab.
You may be told not to eat for a few hours before the biopsy.
The painkiller put in your mouth should numb the area during the procedure. You may feel some tugging or pressure. If there is bleeding, the blood vessels may be sealed off with an electric current or laser. This is called electrocauterization. After the numbness wears off, the area may be sore for a few days.
This test is done to look for the cause of abnormal gum tissue.
This test is only done when gum tissue looks abnormal.
Avoid brushing the area where the biopsy was performed for 1 week.
