Dr. Tung?çös snap-on toothbrush sanitizer is a revolutionary product that releases all-natural, anti-bacterial vapors to kill germs and safely sanitize your toothbrush between brushings. Toothbrushes harbor a host of harmful bacteria that can re-infect your mouth when you brush. Our biodegradable device provides two months of protection and requires no electricity or battery power, making it ideal for home or travel. Our sanitizer contains one or more of the following ingredients to utilize naturally-occurring antibacterial properties: lemon oil, tea tree oil, clove oil and thyme oil. Fits most manual and power brushes. Includes dr. Tung?çös snap-on toothbrush sanitizer-2-pack. Our products have grown out of a passion for bringing healthy smiles naturally. Since our small beginnings, dr. Tung's has always been on the leading edge - we introduced the first commercially available tongue cleaner in 1997, before tongue cleaning was commonly known in the usa, and we now provide innovative products for fresher breath and healthier smiles.
