GUM® SONIC SENSITIVE Battery Toothbrush Refill Heads

Want to get the most out of your GUM SONIC SENSITIVE Battery Toothbrush? Make sure you replace the head every 3 months or as soon as bristles begin to flare out. If you've had a cold or the flu, it's also a good idea to change the head. Designed with ultra soft, bi-level, double tapered bristles that thin out at  both ends, this special head helps you clean hard-to-reach areas of your mouth - between the teeth and below the gum line - where plaque and bacteria tend to accumulate. Compared with a manual flat trim toothbrush, it removes plaque 88% deeper between the teeth. This brush also massages your gums. For an ultra gentle, extra deep clean that will leave your feeling fresh and clean day after day.
