Even Procter & Gamble, maker of Crest toothpaste, is launching a charcoal whitening toothpaste soon. Patients say the black charcoal toothpaste makes a mess and adds an extra step to the morning routine, and despite add dirtiness to teeth, some people think it makes their teeth whiter. Charcoal has been used on teeth for centuries, and while there is no evidence of any danger, there is also no evidence of any benefit. Dentists are concerned with the abrasiveness that wears away teeth. However, charcoal has been all over social media lately in terms of beauty products- from makeups and hair colors to masks. If nothing else than a great selfie, go ahead and try some charcoal toothpaste.
