A gum biopsy, or gingival biopsy, is a very important procedure in which we do at our Beverly Hills office. Dr. Baradaran if necessary will remove a sample of suspicious gum tissue from your mouth, and send it to a lab for analysis. Gum biopsy tests for abnormal or suspicious gum tissue, and is used to diagnose sores or lesions on your gums that last longer than two weeks. Early detection and treatment is critically important. Dr. Baradaran performs a thorough examination of your mouth to rule out any suspicious tissue that may require investigation.
