Is it safe not to rinse toothpaste?

[johnsim]

Hi,

Toothpastes usually state that teeth should be washed for at least a minute. So, it is safe to keep toothpaste in a mouth for at least that much. Is there some period of time after which it is unsafe to keep toothpaste in the mouth? For instance, if I only spit the toothpaste but not rinse with water, then there will be some traces left. Is that safe?

Thanks.

I think you should not worry too much about this. But you don't need to retain paste in your mouth in order to ensure the teeth are clean. You should only use a tiny amount of paste as most of the cleaning is in the brushing and not the paste.
