Thin ridges on the inside and outside of the Elite Flex™ cup allow for better interproximal cleaning, exceptional stain removal, and improved splatter control. The enhanced design is also good for overlapped or crowded dentition as well as interproximal, subgingival, lingual, buccal, and occlusal surfaces. Because it is 25% softer and more flexible than the original Elite Original™ cup, its enhanced softness is optimal for improved flair and flexibility. Elite Extend Flex™ is 19% longer than Elite Flex™.
