Was I surprised when my dentist told me I had a tartar problem? Doctor, I said, I brush with baking soda and peroxide. He said, those aren't tartar fighting ingredients, so your teeth aren't as clean as they could be. Use tartar control crest. But doctor, I said, shouldn't I use baking soda and peroxide for my gums? Pete, he said, they're not proven to do anything special for your gums either. So I used crest. And my tartar problem? No problem. Tartar control crest. It's proven to fight tartar buildup. It's the dentist's choice. No more surprises for me.
