The Oral-B Pro 800 Cross Action Clean Electric Toothbrush is clinically proven to remove 100% more plaque than a regular manual toothbrush. It features Oral-B's new bristle technology, which includes a cross action brush head with green bristles that turn yellow when it's time to change. The pressure sensor alerts you when you're brushing too hard, helping to protect your gums. This toothbrush has one mode, daily clean, and a 2-minute timer to help you brush for the dentist-recommended time. It also features a 3D action with high-speed oscillating, rotating, and pulsating motion, and a long-lasting rechargeable battery. The toothbrush is suitable for women, men, and children over the age of 3. It's essential to replace the brush head every 3 months or sooner if it becomes worn.
