Doctor Plotka’s Mouthwatchers Adult Toothbrush offers a breakthrough in dental hygiene by providing the ultimate cleaning experience. The revolutionary antimicrobial* dual layer flossing bristles, are able to reach those difficult areas, leaving teeth and gums feeling like you’ve been to a professional dental cleaning. The bristles on Mouthwatchers brushes are made with silver embedded into the fabric of the bristles, not coated like other products, meaning it never 'wears out'. It works again and again to automatically eliminate any nasties. Silver has been used for 1000's of years for its antimicrobial properties, in fact Ancient Romans used silver in large containers to prevent liquids from spoiling and today this age old-tradition lives on. *Antimicrobial silver technology reduces bacteria buildup on bristles to keep them clean. It does not eliminate bacteria in the mouth, and does not protect the user from germs or against disease.
