## Features

- No
- Made in US
- SUPERSIZED BRUSH HEAD FOR SUPERIOR CLEANING - The wide oval brush head coupled with a flexible neck helps target those tricky to reach areas more easily, massaging the whole mouth as it goes for an all over tingly clean.
- 3X LONGER LASTING BRISTLES - Made from vegetable based nylon bristles (which in case you're wondering are BPA-free, ADA accepted) the Flex Brush lasts 3X longer than other run of the mill toothbrushes.
- FLEX NECK TECHNOLOGY - The Flex Brush’s wide soft head stems from an angled neck reduces pressure on gums and teeth. Especially if you're a hard brusher. Bristles are softer and more uniquely aligned providing even pressure that reduces chronic issues.
- AWARD WINNING "EASY-GRIP" DESIGN - The RADIUS Flex Brush user friendly handle complies with recommended 45 degree brush to tooth angle and the smart Thumb and Palm design makes it much easier to grip and control.
- ADA ACCEPTED - Accepted by the American Dental Association. All RADIUS Toothbrushes are a must have for clean teeth & gums.
