Abstract

Charcoal toothpastes and powders are fashionable oral hygiene products, intended for toothbrushing, extrinsic stain removal and, it is claimed, 'tooth whitening'. The popularity of charcoal toothpastes is believed to be increasing in many countries across the world, including the UK, US, Japan, India, Thailand, Lithuania, Australia, Hong Kong, China, Korea and Switzerland, where charcoal-based toothpastes have been reported to be produced. It is understood that many patients ask members of their dental team for advice on the use and benefits of charcoal toothpastes and powders, and that such advice is often empirical. The purpose of this article is to provide an overview of the current knowledge and understanding of charcoal toothpastes and powders, including consideration of the strength of the evidence to support claims made by the manufacturers of these products.
