What effect do diuretics have on oral health?

Diuretics are prescribed to remove excess fluid from the body, often for heart failure or high blood pressure. A well-known side effect of diuretics is a dry mouth, because they affect the body's fluid balance. With reduced saliva production, bacteria can multiply more quickly in the mouth. This increases the risk of tooth decay and gum inflammation. Patients who take diuretics often notice a sticky feeling or bad breath due to dryness of the mouth. Saliva substitutes or artificial saliva can offer relief. Drinking water regularly and chewing sugar-free gum helps keep saliva levels up. The periodontist can give advice on adapted oral care to limit the negative effects. Avoiding caffeine and alcohol helps prevent further dehydration. By taking a proactive approach to oral hygiene, the risks of diuretic use remain manageable.
