Is it true that you shouldn’t rinse after brushing your teeth?
Viral TikTok videos have challenged the way many people brush their teeth. Their advice: Brush your teeth with a fluoride-containing toothpaste and spit — but don’t rinse.
Dental experts agree. They recommend brushing at least twice a day with a fluoride-containing toothpaste to help prevent cavities. And they say skipping the rinse after brushing allows the fluoride to stay on the teeth, providing added protection.
