Is there a legitimate reason to buy an expensive electric toothbrush?
I finally bought an electric toothbrush, a $25.00 rechargeable model from the grocery store, and I like it. My teeth feel slick, like after a trip to the dentist. But I also see $180.00 models available. Is it possible that the expensive model is really 8 times as effective? I haven’t been able to find any studies or comparisons; anyone have any good links for me?
