The smart ProtectiveClean toothbrush will help protect your gums. It has a built-in sensor to ket you know when you're applying too much pressure on your teeth. Therefore, it is ideal for anyone, including people with sensitive teeth or gums, and those who wear braces or have dentures. You can choose from three different cleaning modes, including a gentle mode for whiter teeth. An intelligent timer alerts you when it is time to move to other parts of the mouth, and tells you when you've brushed for the recommended amount of time.
