Tips: 1) Don't forget to replace your toothbrush every 6-8 weeks! 2) Don't forget to replace toothbrush after illness (germs can remain on toothbrush - yuck!) 3) Sterilize often - about once a week, we recommend that you immerse the toothbrush head into 10% hydrogen peroxide (widely available from pharmacies). Leave for 10 minutes then rinse with water and allow to air dry. Your child's toothbrush will stay cleaner and last longer.
