Rinse or spit after brushing your teeth? This is kind of a big debate. I’ve polled a lot of my patients, and they’re pretty much split down the middle—and many ask for my opinion on the topic.
From a dental and biologic standpoint, here’s what I recommend.
Why Fluoride Matters
A lot of the toothpastes we use have fluoride in them, and that’s a great thing. Fluoride is a mineral that helps your tooth rebuild the outer enamel and makes the teeth stronger again.
So the theory I subscribe to is this: once you brush your teeth, it’s okay to spit out because you don’t want a bunch of stuff sitting in your mouth. But at that point, I would not recommend rinsing with just water, because then you’re taking away the residual toothpaste and residual fluoride that’s going to sit in your mouth and protect those teeth.
If You Do Want to Rinse
If you want to rinse because you don’t like the taste or you want to get that foamy feeling out of your mouth, rinse with a mouthwash that has an antimicrobial or a fluoride component. That way, you can protect and strengthen your teeth even after rinsing away the toothpaste.
A Note About Fluoride Concerns
I know for some of you, the “f-word”—fluoride—can be overwhelming and concerning. There’s a lot of debate, and I’m not going to touch that. But I will say the amount of fluoride in your toothpaste or in some mouth rinses is absolutely safe, and it does a really good job of protecting your teeth.
In my opinion, it’s wise to let the fluoride do its magic and help prevent early tooth breakdown and decay.
Final Thoughts
No matter where you fall on the spectrum—spit and rinse with water, or just spit and leave it be—I’m just happy that you’re brushing your teeth.
