Product Description:

• For a great brushing experience every day, we recommend you replace the head of your GUM SONIC DAILY battery toothbrush (previously known as GUM ActiVital Sonic) regularly every 3 months or when bristles begin to flare out. If you've had a cold or the flu then you should also change the head.
  This special head features soft, bi-level, tapered bristles that thin out at one end for a superior clean. These bristles allow you to reach and clean hard-to-reach areas where bacteria and plaque tend to accumulate. Compared with those of a manual flat trim toothbrush, they offer 50% more efficacy in cleaning between the teeth and remove 47x more plaque below the gum line.

How To Use:

• Place the new head on the base and push it in. It is recommended to replace the brush head every 3 months.
