Mouthwash and heart health: what the science really shows
Research suggests the link between mouthwash and blood pressure depends on the product. Strong antiseptics like chlorhexidine can disrupt oral bacteria that convert nitrate to nitrite, potentially raising blood pressure in some short-term studies, while milder, everyday mouthwashes have less impact. Alcohol-containing formulations complicate interpretation, and currently there’s no consistent evidence that regular mouthwash use increases heart disease risk. For overall health, maintain good oral hygiene and choose mouthwash based on need and ingredients, using the strongest types only for specific conditions.
