Sonic vibrations with 2-minute timer, 30-second pulses, & multi-use cover.

1,200 soft, end-rounded, DuPont nylon bristles inserted into 34 tufts to give each tooth a gentle yet effective cleaning. We do not and will not supply medium or hard (or "green") bristles as they can be damaging to teeth and gums. Please consult with your dentist if you usually purchase medium or hard bristles.

Vibrates bristles at an industry standard 15,000 brush strokes per minute for an effective yet sensitive cleaning action. The motor pulses every 30 seconds to guide an even clean for your teeth and gums, and automatically stops at 2 minutes to let you know you’re done. Runs on a replaceable (or rechargeable) AAA battery (free on a 3-month refill plan). Battery lasts the same 3 months as your brush head, and should be replaced when changing your brush head. Just slide out the battery and drop in fresh (or fully charged) one.
