Non-fluoride toothpaste not the best for preventing cavities, say dentists

Fluoride. Gotta have it. That’s what a review of dental studies concludes this week about toothpaste.

The University of Washington study determined that, without fluoride, neither brushing or flossing prevents cavities.

Among those not shocked by the verdict on fluoride: Wisconsin Dental Association President, David Clemens

“It really is effective,” Clemens said. “It’s been shown in multiple studies — large studies — that it’s effective.”

Most toothpastes already contain fluoride and those are recognized as cavity blockers. Natural toothpaste marketers have claimed fluoride-free toothpaste also prevents cavities.

But maybe that fennel-flavored natural toothpaste you’ve been swishing around with might not be doing much at all.

The UW review published this week said the so-called natural toothpastes aren’t all that great at preventing cavities — ever. Clemens says stick to fluoride toothpaste.

“It works in a topical manner, for the most part, at strengthening the superficial layers of the enamel of the tooth, allowing it to resist acid erosion as it attacks,” Clemens said.

Unfortunately not believed by everyone, Clemens says.

“Fluoride toothpastes are one of the main things that protect the children,” he said. “So, when we see somebody saying, ‘Don’t use this, it could harm your child.’ Really, what they’re doing is harming their children.”

Clemens says fluoride in water systems can also really help in preventing cavities. He says those that resist both and go the natural route tend to have the biggest tooth problems.
