“Don't rinse your mouth immediately after brushing, as it'll wash away the concentrated fluoride in the remaining toothpaste”

Sorry but that’s unacceptable to me. Come up with a better way for me to clean my teeth or I’ll keep rinsing immediately.

I do actually do this with fluoride and alcohol free mouthwash though. That’s easier to not rinse for 30 minutes.

Well, the free advice and the rationale behind it has been given. Now you can do what you want with it. They're your teeth, after all.
