Research condemns charcoal toothpastes

New research suggests charcoal-based dentifrices may increase the risk of abrasions, contribute to tooth decay and fail to whiten teeth. The BDA’s Prof Damien Walmsley said they offer ‘no silver bullets’ and come with real risks attached. He told those tempted to use them: "Don’t believe the hype. Anyone concerned about staining or discoloured teeth that can’t be shifted by a change in diet, or improvements to their oral hygiene, should see their dentist."
