If it’s been longer than 3 months… this is your sign. Dental hygienist tip: replace your brush head every 3 months, even if it looks fine. Bristles lose effectiveness over time, long before you can see it. 🪥🦷 Swap it out. Your smile will thank you. 😁 #OralB #OralBIO #ElectricToothbrush #PowerToothbrush #OralCare #DentalTips #HealthyGums #DentistApproved #OralBEmployee
