Make Brushing Fun! BPA Free This 4-pack of kids toothbrushes is made with soft bristles and can stand on their own thanks to two small suction cups on the bottom of each brush. Start and end your day with a smile! Soft rounded bristles will protect the enamel of your teeth and protect delicate gums. Changing your toothbrush every 3 months and after being sick will help fight bacteria build-up. Flossing after every meal will help reduce plaque and prevent gum disease.
