It only takes a couple of seconds.
Nobody taught it to you on purpose.
You just picked it up somewhere along the way.
And it feels like the cleanest part of the whole routine.
Before I tell you what it is, you need to know one thing about toothpaste.
Most toothpaste has fluoride in it.
Fluoride helps make your enamel stronger and helps fight cavities.
It works best when it gets to sit on your teeth for a while.
Now picture what happens next.
You set the brush down, fill a cup with water, swish, and spit.
That rinse sends a lot of the fluoride right down the drain.
I know, I know, everybody does it.
So here's the swap.
Spit out the extra toothpaste and skip the water.
Just leave that thin layer of paste on your teeth.
It keeps working after you put the brush down.
Yes, it feels a little weird the first few nights.
You'll get used to it fast.
Try not to eat or drink right after, so it can keep working. [recommended: wait to eat or drink after brushing with fluoride toothpaste]
Mouthwash right after brushing can rinse the fluoride off too.
Save the mouthwash for a different time of day, like after lunch.
