I couldn't find any research about that quote regarding the honey bear, and a few species of bear are sometimes called that. I think its a made up quote that never had any reference to back it up.

I'm guessing if a bear did have cavities its because they love to eat trash! Bears love living by trash dumps and also raid garbage regularly, eating all the junk processed food people throw away...which certainly will give you cavities!!!

Honey does protect teeth from decay, at least raw honey does. If you rub it in your mouth before bed you will not get cavities and it will help your gums and teeth. It will kill the unfriendly bacteria in your mouth.

Raw honey is great, but does need to be limited if you have candida overgrowth.

PS, Getting honey that is raw is even more important than getting organic honey in my opinion. Its a living food and full of enzymes.
