Fight bad breath with the micro-pointed bristles and built-in scraper on your Orabrush® The Orabrush® Tongue Cleaner features ultra-soft, micro-pointed bristles that reach deep into the uneven crevices of your tongue to loosen and lift away stinky bacteria. These bristles are designed after a surgeon's scrub brush. The scraper then collects and removes the bacteria and residue generated from brushing, helping fight bad breath. Replace every 3-4 months.
