One of the things I look forward to when I get my braces off is to see how the Sonicare brush I have feels on my naked teeth. And if in fact brushing with it helps with stain removal/teeth whitening, as they claim.

I googled “sonicare effectiveness” and found an abstract for a 1997 Harvard study that says:

“These results clearly demonstrate that the Sonicare sonic toothbrush is superior to a manual toothbrush in improving periodontal health in adolescent orthodontic patients with existing gingivitis.”

And Phillips (the manufacturer) has a page with clinical study info, including this on how Sonicare does on stains.

I guess I’ll find out soon.
