JADA specialists also highlight that a third of charcoal products contain bentonite clay. Research shows this ingredient may include lead. Even in small doses, this substance is toxic and shouldn’t be used in or on the body.
What’s more, the technique of activated charcoal teeth whitening may bring unwanted side effects.
The ADA states that the abrasive texture of activated charcoal may wear down tooth enamel, especially when used often and for a long time. At first, this may seem like a whitening effect. Only with time or upon a dental exam, does it become obvious that your teeth have been damaged.
Damaging the outer surface of your teeth can lead to staining, which is counterintuitive as charcoal is supposed to make your teeth brighter. When used too intensively, the dentin beneath the enamel can start poking through. The smile then begins to look yellow.

Consult with your dentist

Choose the right product
Activated charcoal may come in the form of toothpaste, powder, or tablets.

Use activated charcoal with caution
If the product goes on your toothbrush, use gentle, circular motions to clean your dentition. In order to make it even safer, you can use your fingers instead of a brush. Simply leaving it on, though, will not give you any effects, as charcoal only whitens thanks to its abrasivity.
Do not reach for the product for long periods of time. Some may state they are safe to use everyday, but there is no evidence to back this up. Instructions on the packaging are vital, but you have to first and foremost adhere to recommendations by your dentist.
A specialist is always more informed on the situation in your mouth than a manufacturer who writes generalized guidelines. Prolonged exposure to activated charcoal may even lead to an overdose.
