One of the most-used household items in any home should be an individualÍs toothbrush. Dental experts report that toothbrushes should be replaced at least 4 times a year, if not more frequently. With over 320 million Americans, thatÍs a lot of toothbrushes in the trash. Worldwide, people add billions of toothbrushes, and the environment-harming materials they are made of, to landfills across the globe.The Spry Dental Defense bamboo toothbrush was developed to address this problem. Organically grown bamboo makes an excellent toothbrush for a number of reasons. No pesticides or chemicals are used in its cultivation, making it an all-natural, sustainable, biodegradable, and eco-friendly alternative to the more-common materials that will take thousands of years to break down.Naturally anti-microbial, bamboo also helps protect the mouth from unfriendly bacteria and other microbes so you can brush with confidence.
