Why Replace Your Brush Head Regularly?
According to the Centers for Disease Control and Prevention (CDC), maintaining consistent oral hygiene — including regular toothbrush head replacement — is a key part of good oral health. Worn bristles are far less effective at removing plaque, so swapping your head every 3 months keeps your routine at peak performance.
