80% of bad breath comes from a dirty tongue (The Dental School of the Univeristy of Buffalo, NY). The Orabrush® Tongue Cleaner has ultra-soft, micro-pointed bristles and a built-in tongue scraper that collects and removes the bacteria and residue generated from brushing, helping to fight bad breath. Designed after a surgeon's scrub brush, Orabrush (R)'s bristles reach deep into the uneven areas of your tongue removing bad breath bacteria; toothbrush bristles sweep the smooth surfaces of your teeth, not clean down into the crevices of your tongue where stinky gunk hides.
