Orabrush individual, ultra soft bristles reach deep into the uneven areas of your tongue, removing the source of bad breath. The scraper then squeegees off the loosened material. Tongue bacteria account for 80-90% of all cases of bad breath (dental school of the University of Buffalo, NY). Orabrush is far superior to any tongue cleaner I have used (Dr. C. Lynn Hurst, DDS MS dean, college of dental medicine). Moisten your tongue (using Orabrush tongue foam or water). Gently brush several times with your Orabrush. Reach the scraper towards the back of your tongue and remove the residue generated from brushing.
