What you should know about Charcoal Toothpaste

There is lots of online talk about charcoal toothpastes and their benefits. Two main benefits reported are whiter teeth via stain removal and overall health benefits of filtering/scavenging activity of charcoal grabbing onto bacteria, toxins, etc.

From our point of view [The Marshall Clinic], we do not recommend charcoal toothpastes because if they are effective it will be through excessive abrasiveness [virtually all “whitening” toothpastes have RDA values higher than is recommended…..essentially they make teeth whiter by stripping off the surface layer of enamel] and because they are being used topically [not being swallowed] there will be minimal to no effects systemically that could impact overall health.

What is RDA?
To help quantify the abrasivity, the ADA along with various academic, industry and agencies established a standardized scale called Relative Dentin Abrasivity (RDA). This scale assigns a value from 0 to 250.

Our advice for toothpastes is to find one you like the taste of, that has low abrasiveness [less than 90 RDA value], has fluoride, has basic pH, sweetened with Xylitol only and doesn’t contain SLS [sodium lauryl sulphate].

There are many whitening systems for your teeth. Feel free to contact us if you would like more information about how to safely whiten your teeth.
