Brushing Teeth

Question

I’ve heard that after brushing, you’re not supposed to rinse with water. If American water has fluoride, why would this be a bad thing? I always thought toothpaste was supposed to be rinsed like soap. Plus, it’s toxic if swallowed. Why is rinsing after brushing bad?

Answer 1

Toothpaste contains some things that could be toxic, but not in the little amounts that it is in there.
On the topic of rinsing: you shouldn’t do it immediately because even though your tap water may contain fluoride, the tooth paste has a much higher concentration of it and rinsing it, dilutes the effect.
You can rinse after 20 minutes.
