Our Rowe Naturals bamboo and boar bristle toothbrush is made with 100% bamboo and boar bristles, and nothing else. Brush your teeth with an all-natural toothbrush made without plastic or petroleum products. Most toothbrushes are made with plastic, nylon, petroleum, and toxic glue- that isn't something you want brushing into your gums and putting in your body. That's why we are providing a safer alternative to brushing teeth at Rowe Naturals, so you don't have to worry about the toxicity in your toothbrush anymore. Made with medium-firm bristles that clean the teeth without scraping enamel or gums like nylon toothbrushes. The boar bristles on our toothbrushes are medium-firm stiffness, which clean the teeth well without scraping the enamel like nylon toothbrushes do. Reduce your ecological footprint by choosing a biodegradable toothbrush Our toothbrushes are 100% biodegradable. When you are done with it, you can throw it in your compost! Did you know? Bamboo cultivation is environmentally friendly because it requires no fertilizers, herbicides, or pesticides. It also restores the soil by eliminating toxins. These characteristics give bamboo an excellent ecological rating. Care and Use To soften bristles, soak in warm water. Store tooth brush in dry environment. Rinse brush thoroughly after each use. Replace brush every 6-8 weeks.
