Does charcoal toothpaste really whiten teeth, or can it damage your teeth?

### Why does this happen? Many people believe that expensive charcoal toothpaste makes their teeth whiter. Charcoal toothpaste has become very popular due to promotions on social media. While it may scrub away temporary surface stains from coffee or food, it is not a permanent teeth whitening solution. ### Understanding Tooth Enamel Abrasion An essential clinical factor is the Relative Dentin Abrasivity (RDA) index. The higher the abrasivity level of a toothpaste, the more enamel it wears down over time. Charcoal toothpastes typically feature high RDA scores. With long-term use, charcoal particles gradually erode the outer protective enamel layer. As enamel thins, the underlying yellowish dentin becomes visible, making teeth look more yellow while increasing hot and cold tooth sensitivity. ### Which doctor should you consult? Remember, once tooth enamel is worn away, it cannot regenerate naturally. If you are experiencing tooth sensitivity or are unsure which toothpaste is appropriate for your teeth, consult your nearby dentist for professional evaluation.
