How High Blood Pressure Medication Could Cause Swollen Gums

If you have high blood pressure, your medical doctor may prescribe calcium channel blockers to help control it. However, that can have a side effect of sore, swollen gums that can be disturbing if you don't expect it.

Calcium channel blockers can cause gingival (gum) overgrowth, said Dr. Michael Quinn, a periodontist who practices at several Coast Dental offices in the Atlanta area. The gums feel swollen, lumpy, hard and thick. They may not bleed and the color remains pink, but the change in texture affects how your mouth looks and feels and your ability to brush and floss. It inhibits your ability to floss between teeth, so bacteria accumulate above and below the gum line. The bacteria attack the bone supporting your teeth, causing the bone to disintegrate and your teeth to loosen.

Fortunately, a change in medication can make a big difference. Dr. Quinn had a patient whose gums were mushrooming after taking the calcium channel blocker his doctor had prescribed (pictured). Dr. Quinn wrote a letter to the physician explaining the side effect and asking for the patient's medication to be changed. Within two months, most of the patient's gum tissue had returned almost to normal, allowing Dr. Quinn to plan treatment to resolve the remaining periodontal conditions.

Gingival Overgrowth caused by high blood pressure medication

Several drugs designed to control cardiovascular disease can cause other side effects too, including dry mouth. Saliva helps wash away plaque, a sticky film of bacteria that constantly forms on your teeth and can harden into cavity-causing tartar. If the mouth isn't producing enough saliva, the plaque stays longer on the teeth, making them more prone to cavities. Some drugs can also affect how food and beverages taste.

If you're experiencing any of these side effects, talk to your dentist about your options.
