Charcoal & Purple Toothpastes

Charcoal toothpaste is a big-a-no-no! I have seen patients whose enamel has become eroded due to daily charcoal toothpaste use and you cannot regrow enamel!

Charcoal Toothpaste vs Purple Toothpaste

They both have been popular trends in oral care--each with their specific claims about benefits…

Charcoal Toothpaste

These black powder and pastes recommend brushing for several minutes, usually once or twice a day, over an extended period of time (weeks or months depending on the product). Promises range from a whiter, brighter smile, to a cleaner, healthier mouth due to its abrasive nature and adsorptive properties.

However, while charcoal can help remove surface stains on the teeth, it's not more effective than other whitening toothpastes and can be too abrasive for daily use. This abrasion can lead to enamel damage over time. The Canadian Dental Association (CDA) has not approved any charcoal toothpastes due to lack of evidence regarding safety and efficacy.

Purple Toothpaste

Purple toothpaste is typically marketed as a way to counteract yellow tones in teeth, similar to how purple shampoos work to neutralize yellow tones in hair.

These toothpastes often contain a blue or purple tinting agent that make teeth appear less yellow temporarily by creating an optical illusion. However, they do not change the actual color of the tooth enamel or remove stains permanently. It cannot chemically bond to your teeth like shampoo bonds to your hair. Once your saliva (your spit) touches your teeth, the effects (if any) are immediately gone.

Charcoal Toothpaste vs Purple Toothpaste for Teeth Whitening

Don’t waste your time or money on charcoal or purple toothpastes. For effective and safe whitening results, it's recommended to use products that are approved by the Canadian Dental Association (having the CDA seal of acceptance) and to consult with your dental provider prior to whitening.
