A member asked:

Some reports say to preserve the benefit of fluoride, you have to wait b30 min before rinsing with water after brushing teeth,. how is it possible?

A doctor has provided 1 answer

Topical fluoride: The fluoride needs time to penetrate through the enamel of the teeth in order to replace the existing ions with cavity-resistant fluorine ions. It's better to wait to rinse so that you don't wash off the topical fluoride.
