Charcoal Toothpaste Doesn't Whiten Teeth, Says Report Have you heard that charcoal can make your teeth whiter? Turns out this may not be true. Charcoal-based toothpaste is a "marketing gimmick" that may actually harm your dental health. A 'British Dental Journal' report has revealed that most charcoal toothpastes don't have any fluoride to protect teeth. Charcoal toothpastes often erroneously claim to be "anti-bacterial" and "anti-fungal." Because they are more abrasive than traditional toothpastes, they may wear down tooth enamel.
