This is the travel toothbrush that vibrates up to 31,000 times a minute to help one maintain optimal oral hygiene when away from home. This toothbrush cleans with all the vigor of its full-sized counterparts yet is no larger than a pen, making it ideal for use at the gym, office, or when taking a trip. The intense sonic pulsations are gentle on gums yet merciless on plaque and bacteria, cleaning more effectively than ordinary toothbrushes to help prevent tooth decay. A lower speed setting reduces the vibrations to 22,000 per minute and a vented cap allows water vapor to escape to help keep the brush head dry between uses. Includes three brush heads (each provides about three months of continuous use), travel bag, and one AAA battery. Silver. 6 1/2" L x 1" diameter. (2 1/2 oz.)
