Teeth whitening toothpaste may help remove surface stains on your teeth. Some of them contain charcoal which is mildly abrasive and is also able to absorb surface stains to some degree.
There is no evidence, though, that teeth whitening toothpaste has any effect on stains below a tooth’s enamel, or that it has a natural whitening effect.
In order to whiten teeth, a product needs to work on stains on the surface, as well as intrinsic stains, which are those below the enamel.
While activated charcoal does have some proven benefits, there isn’t enough scientific evidence to include teeth whitening as one of them.
Is Teeth Whitening Toothpaste Safe?

Here’s what we do know about charcoal toothpaste so far:
- Teeth whitening toothpaste is too abrasive for everyday use. Using a material that’s too abrasive on your teeth can wear down your enamel. This may make your teeth look more yellow by exposing the dentin, a calcified yellow tissue. It can also make your teeth more sensitive.
- Most teeth whitening toothpaste brands don’t contain fluoride. Fluoride helps keep your tooth enamel strong, which helps to protect your teeth against cavities and decay. There is some evidence linking charcoal toothpaste to increased tooth decay.
- Charcoal may cause staining on some teeth. Charcoal particles could accumulate in the cracks and crevices of older teeth.
- Charcoal’s effect on dental restorations isn’t known. It’s not yet known how charcoal affects the materials used to make veneers, bridges, crowns, and white fillings. Particles of charcoal could build up between them, leaving a black or gray outline.
