The importance of brushing your teeth has been drilled into your head since childhood—and now there's plenty of technology out there to make the experience virtually foolproof. This line of ionic toothbrushes from IONPA works by breaking the bond that plaque has on your teeth, so it can be easily brushed away. The thinking is that plaque bonds to teeth through a positive ion charge, and negative ions from the bristles of the brush work to loosen and eventually break the bond. And there is evidence that shows ionic brushes are effective when it comes to reducing plaque and the threat of gingivitis.

If that sounds like a better alternative than the $2 manual brush you get from the gas station every couple of months, you can pick up one of the IONPA brushes below while they're on sale.
