How To Remove Tooth Stains from Coffee and Cigarette Smoke

A recent study published in the Journal of the American Dental Association evaluated the stain removal ability of toothbleaching and simulated toothbrushing after coffee and cigarette smoke staining.  In addition, researchers determined the enamel susceptibility to restaining.  They measured tooth color with a colorimeter, before and after immersing half of the samples in coffee and exposing the other half in a smoking machine.  Then they remeasured color after toothbleaching and toothbrushing.  They found specimens stained with coffee and smoke showed a significant removal of stain after bleaching.  However, only the smoke stained specimens responded to toothbrushing.  The authors concluded that 6% hydrogen peroxide at-home bleaching removed both coffee and smoke staining.  However, restaining potential was greater for tooth surfaces stained with coffee than for those stained with cigarette smoke, regardless of the removal method used.  Finally, the authors wrote, continued frequent consumption of coffee can increase the staining susceptibility of enamel.
