A gum biopsy is a surgery in which a small piece of gingival (gum) tissue is removed for examination.
Biopsy - gingiva (gums)
How the test is performed
A painkiller is sprayed into the mouth in the area of the abnormal gum tissue. In some cases, a numbing injection may be used. A small piece of the gum tissue that appears abnormal is removed and checked for problems in the laboratory.
How to prepare for the test
There is no special preparation, although you may be told not to eat for a few hours before the biopsy.
How the test will feel
The topical anesthetic should numb the area during the procedure, although some tugging or pressure may be felt. 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.
Why the test is performed

“[Bisphosphonate] usage has been linked to the catastrophic condition ‘Dead Jaw.’ If you or a loved one have taken any of these drugs for osteoporosis… & you have experienced complications, you must act now! You may deserve compensation. For a free confidential case evaluation…” So reads the callout on a particular Web site devoted to “litigation regarding Bisphosphonate Complications.” Contrast that with this, from modernmedicine.com, “an online resource designed to meet the evolving needs of physicians,” November 15, 2008: “The last word on this controversy [the connection between bisphosphonate use and ONJ] has yet to be said, but according to a review of the literature by the American Society for Bone and Mineral Research, the risk of ONJ associated with oral bisphosphonate therapy for osteoporosis seems to be low, estimated between 1 in 10,000 and <1 in 100,000 patient treatment years.” ONJ. “Bi...
Receding gums occur when the gums and the bone in the mouth have moved away from the tooth. Receding gums may be caused by gum disease, imbalanced occlusion (the way the teeth fit together when you bite down), or trauma. Accumulation of plaque at the gum line and poor oral hygiene can lead to receding gums. Bacteria on the plaque release toxic substances that can cause destruction of gum tissue. When occlusion (the way teeth come together) is imbalanced, excessive forces placed on the teeth cause trauma to the bone and gums. Gum recession exposes the roots, causing the teeth to become sensitive to hot, cold, sweet, and salty substances. Excessive pressure resulting from grinding or clenching teeth may cause the gums to recede. Receding gums may occur when teeth are crooked or fillings and crowns are placed without properly balancing the bite. In both of these cases, the teeth do not come together properly, and increased forces are placed on certain parts of the teeth. Initially, the gums ...
