Toothpaste
Created | Updated May 27, 2003
Toothpaste is used on toothbrushes by humans to brush their teeth. They could brush their teeth without toothpaste, but then only the abrasion of brushing the teeth would act to clean them, rather than the bacteria removal action of toothpaste. Modern toothpaste comes with fluorine included, so fluorine supplements are no longer needed. As toothpaste can cause irritation against the gums, there are some sensitive toothpastes.
