By adding tongue cleaner to your usual dental care, you can prevent bad breath and lower the risk of tooth decay and periodontal disease. The simple and easy-to-use design allows you to gently remove dirt without hurting your tongue. The curved tip fits securely to the surface underneath. 【How to use】 Rinse the tongue cleaner too gently before use. Turn the side with the logo up, and gently slide the tongue cleaner from the back of the tongue to the front. Repeat several times until the stain is gone. Rinse off dirt from the tongue cleaner with running water and dry it thoroughly before storing. 【Notes】 Do not rub the surface of the tongue too hard. Be careful not to irritate the back of the tongue, as it will cause nausea.
