Most of the time I brush my teeth, I do so on the can. As such, I cannot easily void my mouth at the end of brushing.
Just looking at it from the perspective of keeping the end product in my mouth for a minute or more, is this good bad or indifferent to my mouth? I.e. is this combination of toothpaste and saliva somehow bad for my teeth, or could keeping this fluoridated mixture somehow give me more protection, or won’t it matter?
