Throughout the medical field, a biopsy is simply the removal of a tissue sample to determine if it is diseases. In dentistry, teeth and gums are sent for biopsy. The role of a biopsy in the dental industry is to diagnose oral cancer. In these instances, a brush biopsy is used to identify oral lesions that warrant further attention.

If you have unexplained lesions in your mouth, they need to be examined by a dentist. They may or may not be cancerous, but they need medical attention nonetheless.

According to, "there are several different types of gum biopsies.

Incisional biopsy

An incisional gum biopsy is the most common method of gum biopsy. Your doctor will remove a portion of suspicious tissue and examine it under a microscope.

A pathologist can determine if there are cancerous cells in the removed gum tissue. They can also verify the origin of the cells, or if they’ve spread to the gum from somewhere else in your body.

Excisional biopsy

During an excisional gum biopsy, your doctor may remove an entire growth or lesion.

This type of biopsy is normally used to take out a small lesion that’s easy to reach. Your doctor will remove the growth along with some of the nearby healthy tissue.

Percutaneous biopsy

Percutaneous biopsies are procedures where a doctor inserts a biopsy needle through your skin. There are two different types: fine needle biopsy and core needle biopsy.

A fine needle biopsy works best for lesions that are easy to see and feel. A core needle biopsy provides more tissue than a fine needle biopsy. This can be useful when more tissue is required for your doctor to make a diagnosis.

Brush biopsy

A brush biopsy is a noninvasive procedure. Your doctor will gather tissue by forcefully rubbing a brush against the abnormal area of your gum.

A brush biopsy is often your doctor’s first step if your symptoms don’t call for an immediate, more invasive biopsy. It’s used for an initial evaluation.

If the test results show any suspicious or abnormal cells or cancer, your doctor will likely do an incisional or percutaneous biopsy to confirm a diagnosis.

What is a gum biopsy test used for?

A gum biopsy tests for abnormal or suspicious gum tissue. Your doctor may recommend it to help diagnose:

  • a sore or lesion on your gum that lasts longer than two weeks
  • a white or red patch on your gum
  • ulcers on your gum
  • swelling of your gum that doesn’t go away
  • changes in your gums that cause loose teeth or dentures

A gum biopsy can also be used along with imaging tests to reveal the stage of existing gum cancer. Imaging tests include X-rays, CT scans, and MRI scans.

The information from the gum biopsy, along with the findings of imaging tests, can help your doctor diagnose gum cancer as early as possible. An earlier diagnosis means less scarring from removal of tumors and a higher rate of survival."
