    That you aren’t supposed to rinse immediately after brushing your teeth. It’s better to wait 15 minutes to let the fluoride strengthen your enamel.

    Been brushing the wrong way for 30 years, apparently.

      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?

      And if you throw up, don’t brush your teeth as you’re then just scrubbing stomach acid into them. Rinse and gargle with water then brush an hour later
