The use of charcoal toothpaste has become popular in teeth whitening, yet is this product really safe in daily use. In Smilex Dental Clinic, our dental practitioners discuss the effect of activated charcoal on your teeth, its value, as well as its possible dangers. Although charcoal was found to be beneficial in taking away surface stains, excessive use of charcoal disrupts enamel and leads to sensitivity in the teeth. Understand when to use charcoal, when not to use it and what the dentists at Smilex suggest as the safe and effective way to whiten teeth.
