News24xx.com - A new study by the British Dental Journal found that toothpaste made from charcoal can actually increase the risk of abrasions and contribute to tooth decay and even fail to whiten teeth.
Quoted from Metro.co.uk, toothpaste should contain fluoride which is needed to combat tooth decay. In fact, after going through a cob test on 50 charcoal-based toothpastes, only 8 percent contained fluoride.
50 percent of charcoal toothpaste is claimed to have therapeutic benefits while 30 percent is claimed to strengthen teeth. The rest claim the benefits of antibacterial and antiseptic. After being researched, none of the claims from these products are proven.
Dr. Linda Greenwall, lead author of the study from the British Dental Bleaching Society, said it was very important to look for toothpastes containing calcium, fluoride and phosphate because these are all needed to strengthen tooth enamel.
"Toothpaste must have fluoride to have additional health benefits on the teeth. The most worrying aspect of charcoal toothpaste is that none of them are proven can do what they claimed they can" she said.
