Activated charcoal has recently become a popular trend for DIY teeth whitening, but medical professionals are warning against smearing the charcoal-derived black mixture on teeth.
Fox News reported that YouTube user Mama Natural posted a video detailing how to use activated charcoal to whiten teeth, and by Monday morning the video had amassed more than 1.5 million views.
But dentists are concerned about using this method for teeth whitening, saying it could lead to tooth erosion and enamel deterioration.
The online video shows host Genevieve brushing her teeth with the supplement for three to five minutes before rinsing, then stating she has seemingly whiter teeth. The advertisement advises that the product can be purchased in capsule form online or in health food stores.
Genevieve says in the video that charcoal is highly absorbent, referring to it as “some of the most absorbent material on the planet.” She claims that hospitals have a supply of charcoal on hand to absorb poison from a person’s body.
