I’m a Dentist — Here’s the Truth About Rinsing After Brushing Your Teeth
The Risks of Rinsing After Brushing
For years, we’ve been told to spit and rinse after brushing our teeth, but dental experts are now saying that this habit may not be the best approach. According to Brittany Seymour, a representative for the American Dental Association and a Harvard School of Dental Medicine professor, we should simply brush our teeth at least twice a day with a fluoride-containing toothpaste — full stop.
Rinsing Away the Good Stuff
When you rinse after brushing, you’re essentially rinsing away the active ingredients of the toothpaste that you just applied to your teeth. “When you rinse, you are basically rinsing away the active ingredients of the toothpaste that you just put on your teeth,” says Margherita Fontana, a teacher at the University of Michigan School of Dentistry. This can erase some of the fluoride left over from the toothpaste, which is important for oral health.
A Better Approach
If you do need to rinse, it’s best to do so 20 minutes after brushing or take a small sip of water. Another option is to follow up with a mouthwash containing fluoride, suggests Fontana. This can help keep the benefits of the toothpaste on your teeth for a longer period.
The Science Behind It
A 1999 study of over 2,800 teenagers in England found that those who used less water in their mouths after brushing had fewer cavities and decaying teeth than those who rinsed thoroughly. The study also suggested that for people with healthier teeth, skipping the rinse isn’t as important as for those with a high-sugar diet.
The Importance of Fluoride
The extra fluoride left in the mouth from the toothpaste can be a big help in cases where oral health is a concern. “When you rinse, you are basically rinsing away the active ingredients of the toothpaste that you just put on your teeth,” says a dentist. This is especially important for children, who may be more prone to ingesting toothpaste and fluoride.
Fluoride and Children
For children, it’s important to monitor the amount of fluoride ingested. For kids under three, a pea-sized amount of toothpaste is recommended, while children between three and six should use a smear or “smidge” the size of a rice grain. Pediatric dentist Scott Cashion advises that children should spit out as much toothpaste as possible to prevent swallowing and not rinse afterwards. “When they go off to bed, if there’s fluoride on those teeth, it’s going to help protect them through the night,” he says.
The Dangers of Over-Fluoridation
Dr. Ellie Phillips, a Texas-based dentist, warns that drinking too much water throughout the day can actually be bad for your teeth. In a TikTok video, she explained that sipping on water constantly can dilute the saliva’s healing properties and reduce its benefits. Saliva contains proteins that protect tooth enamel and prevent tooth decay, so excessive water intake can actually be counterproductive.
Conclusion
In conclusion, the American Dental Association recommends brushing your teeth at least twice a day with a fluoride-containing toothpaste, and avoiding rinsing afterwards. Instead, try spitting out as much toothpaste as possible and using a fluoride mouthwash if needed. By following these tips, you can keep your teeth healthy and strong for years to come.
