Earlier quoted context omitted.
You can spit but don't add water. That should get rid of most of it.
Right but the question is for how long? Surely you're not supposed to never put water in your mouth again, so how long should you wait? 1 minute? 10 minutes? An hour?
I used to rinse my mouth with water, now I just spit the toothpaste.
I haven't asked but this may be recommended only if you're not using an abrasive toothpaste which could damage your teeth enamel.
