Spit, Don’t Rinse? The Fluoride Tip Reddit Keeps Sharing

After brushing with fluoride toothpaste, spit out the foam instead of rinsing right away.

Leaving a thin fluoride layer on teeth helps it work longer against decay.

Many people wait around 20–30 minutes before eating or drinking after brushing.

If you must drink water soon, do it lightly and avoid strong rinsing.

Use a routine you can keep consistently; technique matters as much as products.

If you have sensitivity or dental work, ask your dentist what’s best for you.
