If you're concerned about your dental health (and I hope you are), one of the best investments you can make is in an electric toothbrush. Research has shown that the circular motion made by electric toothbrushes is more effective than the up and down motion made by a standard hand-held brush.

Years ago, owning an electric toothbrush meant shelling out a pretty penny, but that's no longer necessarily the case. You can get a battery powered toothbrush for under $10, although you certainly can still spend over $100 for a good rechargeable one.

Consumersearch.com has some of the top ranked toothbrushes -- click through the gallery to see which might be the best match for your mouth. After all, while it's great to have toned abs and firm thighs, a beautiful, healthy smile is often the first thing people notice, and you owe it to yourself to keep it that way!
