Amlodipine and gum swelling
Why amlodipine causes gum overgrowth, who is at risk, and what to do about swollen, bleeding gums on this blood pressure medication.
Never start, stop, or change a medication based on what you read here. Bring questions to your dentist, physician, pharmacist, or prescribing clinician.
Quick answer
Yes, amlodipine can cause gum overgrowth. Studies estimate it happens in roughly 1 in 5 patients on the medication. The technical name is drug-influenced gingival enlargement. It is usually treatable without stopping the medication, through deep cleanings, improved daily plaque control, and in some cases minor surgical reshaping. Talk to your dentist before assuming the swelling is just normal gum disease, because the management plan is different.
The mechanism
Why amlodipine causes gum overgrowth
Amlodipine belongs to a class of blood pressure medications called calcium channel blockers. These drugs interfere with the way certain cells respond to calcium signals. In gum tissue, this interference appears to drive fibroblasts (the cells that build connective tissue) to overproduce collagen and extracellular matrix, especially where plaque is already irritating the gums.
The result is gum tissue that grows larger than normal, bunching up around teeth. The overgrowth tends to start at the gum line between teeth and can eventually cover significant portions of the crown. The tissue often bleeds easily, traps plaque, and creates a feedback loop where plaque drives more inflammation, which drives more overgrowth.
This is not the same condition as ordinary gum disease, even though it can look similar. The difference matters because standard periodontal therapy alone often is not enough: even with excellent home care, the overgrowth tends to persist as long as the patient is on the medication.
