The DenTek Tongue Cleaner helps remove bad breath at the source! Its Mouthwash Blast Mint infused flavor with 3 cleaning edges helps remove bad breath where brushing alone fails. The middle edge scrubs, while the two green edges scrape it away. Majority of bad breath is the result of volatile sulfur compounds produced by bacteria on the back of your tongue where your toothbrush can't reach. Gum and mints just mask bad breath. To do the job right, you need to remove the actual bad breath from where it lives: your tongue. The DenTek Tongue Cleaner is triple edged for extra bacteria removal, easy to use for both adults and children. Caution: Children under the age of 10 require adult supervision while using this product. For best results, replace tongue cleaner when you replace your toothbrush. Go beyond brushing with DenTek! Help preserve and protect your teeth for a lifetime with DenTek's innovative dental care products.
