There are tons of different teeth cleaners on the market, but they often focus on bristles and handles; the chemical-releasing toothbrushes hopes to change that. It is a patent-pending design that would put the toothbrush on a level playing field with its counterpart: toothpaste.
Conceived by Colgate-Palmolive, the chemical-releasing toothbrushes would enhance the experience of oral hygiene by way of a special patch. Not only could this patch come in different flavors such as mint and lemon, they could potentially release different chemicals including caffeine and pain killers. As the American company puts it, "While consumers may seek to clean their tongue or teeth, there has not been a toothbrush which provides a chemical sensory response in a mouth to enhance a user’s brushing experience."
