Healthy Living: Dentist warns about charcoal teeth whitening products
If you're looking for a whiter smile, be warned, some products may do more harm than good. That's the advice from Dr. Larry Kuhl with Delta Dental of Washington. One of those products is charcoal. Dr. Kuhl says charcoal has been around for hundreds of years, but only recently we're seeing it in beauty products. Charcoal toothpastes and powders claim to remove dark and pesky stains like coffee, tea and red wine on the teeth. Dr. Kuhl says although charcoal may temporarily whiten teeth, it can be abrasive and wear off the tooth enamel in the long term.
