If you’re taking medication to regulate your blood pressure, you may be familiar with some of the general side effects, like nausea, drowsiness or dizziness. But some blood pressure drugs might also cause complications with your oral health.
This is true of one class of drugs in particular used for blood pressure regulation. Calcium channel blockers (CCBs) are used to regulate blood pressure by dilating (relaxing) blood vessels, making it easier for the heart to pump blood. They’re often prescribed to patients who can’t tolerate beta blockers, another common blood pressure drug.
Besides other general side effects, CCBs can also cause gingival hyperplasia (gum overgrowth) and mouth dryness. The former condition occurs when the gum tissues grow and extend beyond their normal size over the teeth. Besides pain and discomfort, hyperplasia creates an abnormal appearance which can be embarrassing. Research findings also indicate that hyperplasia development from CCB use is also linked to poor hygiene habits, which give rise to periodontal (gum) disease.
Mouth dryness is defined as less than normal saliva flow. Besides discomfort, the condition may increase your risk of dental disease: saliva is a key part in keeping bacterial levels low and maintaining the mineral content of enamel. Inadequate saliva flow can’t maintain this balance, which increases the bacterial population in the mouth and the risk of infection leading to gum disease or tooth decay.
To avoid both of these side effects, it’s important first to let us know if you’re taking blood pressure medication and what kind. You may also need more frequent dental visits, especially if you’re displaying symptoms of dental disease. Studies have found that frequent dental visits to remove bacterial plaque and calculus (hardened plaque deposits) may significantly reduce gum overgrowth in patients taking a CCB. You should also maintain a recommended daily regimen of oral hygiene (brushing and flossing).
Because of possible effects on your dental health from a number of drugs, it’s always important to let us know the medications you’re regularly taking. As with CCBs, we can incorporate that knowledge into your dental treatment to assure your safety and optimal oral health.
