Rinsing with water or mouthwash immediately after brushing washes away the concentrated fluoride left by your toothpaste, reducing its ability to strengthen enamel and prevent cavities by up to 25%.
Skipping the rinse keeps this protective, high-concentration fluoride on your teeth, allowing for better, longer-lasting protection against tooth decay.
Best to rinse before brushing, or wait 30 minutes after brushing.
