The research was published in the British Dental Journalist. For the research, researchers from the University of Manchester examined 50 different charcoal toothpastes. What turned out to be? Most toothpastes with charcoal would cause tooth decay in the long term.
It also turned out that the toothpaste does not whiten your teeth, but rather darkens it! According to the scientists, this is due to the abrasive effect of the charcoal powder in this type of toothpaste.
This abrasive effect ensures that stubborn dirt disappears from your teeth, but you actually boar too hard. As a result, the enamel on your teeth can be affected and the layer underneath will be exposed, and this layer is darker. In turn, damaged tooth enamel can cause sensitive teeth and that can cause you to get cavities faster.
It is recommended not to use the black toothpaste more than once a month unless the powder is extra fine.
