How should a fluoride rinse be used?

The first rule in using a fluoride rinse? Spit, don't swallow. Read the label carefully before you use it. Generally, you'll brush your teeth first with a fluoride toothpaste and then swish the rinse around in your mouth for a minute or so before you spit it out. That one-minute swish is enough to add an extra layer of protective fluoride to the surface of your teeth, which can make a big difference in your risk for tooth decay.

After brushing your teeth, measure out the appropriate amount of fluoride rinse from the bottle and swish it around in your mouth. Then spit it out. Never swallow the fluoride rinse liquid, because that can be harmful. Talk to your dentist or pharmacist to see if a fluoride rinse is right for you.

A fluoride rinse, which may be prescribed by your dentist or purchased over-the-counter, is used to help protect teeth from cavities in both adults and children older than 6 years. Choose a product with the American Dental Association’s Seal of Acceptance. Use the fluoridated mouth rinse once a day, after brushing your teeth. Follow instructions on the bottle to measure out the proper dose of 10 milliliters. Swish the rinse in your mouth for a minute before spitting it out. Be sure not to swallow it, and make sure any children who use it don’t swallow. Don’t eat or drink for 30 minutes.
