Gum biopsy

Alternative names:

biopsy - gingiva (gums)

How the test is performed:

A topical anesthetic may (or may not) be sprayed in the mouth on the suspicious area of gum tissue. A small piece of the gum tissue is removed and sent to the laboratory for examination.

How to prepare for the test:

Adults:
There is no special preparation, although fasting for a few hours before the test may be advisable.

Infants and children:
The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust. For specific information regarding how you can prepare your child, see the following topics as they correspond to your child's age:

• infant test or procedure preparation (birth to 1 year)
• toddler test or procedure preparation (1 to 3 years)
• preschooler test or procedure preparation (3 to 6 years)
• schoolage test or procedure preparation (6 to 12 years)
• adolescent test or procedure preparation (12 to 18 years)

How the test will feel:

The topical anesthetic, if used, should numb the area during the procedure, although some tugging or pressure may be felt. After the anesthetic wears off, the area may be tender for a few days.

Why the test is performed:

This test is performed when examination of the mouth reveals abnormal-appearing gum tissue, particularly if amyloid or other abnormality is suspected.
