CNET News (7/3, Capritto) reports on the use of activated charcoal in toothpaste. Though CNET says the ads for charcoal toothpaste claim "you'll get a noticeably whiter smile after just one use" in addition to anecdotal claims that "charcoal toothpaste prevents cavities or otherwise promotes better oral health", there's "no evidence to support that." CNET adds, "The evidence is limited, and there's no proof that charcoal toothpaste actually does the things that the Internet claims it does."
Patients can go to MouthHealthy.org, ADA's consumer website, for evidence-based information about teeth whitening, including information on natural teeth whitening methods. The ADA provides a complete list of toothpastes with the ADA Seal of Acceptance, including some with stain removal attributes.
