Use the tooth brush and running water to brush your tongue clean, and spit a few times. That way you get a clean tasting/feeling mouth while not rinsing the suds from your teeth.
Yeah. I had to give a "how to" class and I picked brushing your teeth as a simple topic. I got to the end after brushing your teeth. I said rinse your mouth out and your done. The instructor said "the presentation was okay, but you aren't supposed to rinse your teeth out right away."
I had no idea as amid to late 20 something at the time. What else do you do wrong?
So I tried this for a few months last year. Although I didn’t rinse 15 mins afterwards or anything - I just spit as much of the toothpaste out as I could.
Couldn’t really tell a difference other than it was strange feeling to have all the toothpaste remnants in your mouth. Maybe my teeth were slightly whiter? I eventually went back to my old ways of rinsing. Maybe I’ll try it again though.
