Most charcoal toothpastes rely on abrasive particles to remove surface stains from coffee, tea, wine, or tobacco. This can make teeth look temporarily brighter. However, this same abrasiveness can also wear down tooth enamel, which is the protective outer layer of your teeth. Once enamel is lost, it does not grow back, and teeth may become more sensitive, more yellow-looking (as the underlying dentin shows through), and more prone to cavities.
Another concern is that many charcoal toothpastes do not contain fluoride. Fluoride is a key ingredient that strengthens enamel and helps prevent tooth decay. Without it, your teeth may be at a higher risk for cavities over time, even if they appear cleaner or whiter on the surface.
For most patients, charcoal toothpaste is considered safe for occasional use, such as once or twice a week, but it is not recommended as an everyday toothpaste. People with sensitive teeth, gum recession, or existing enamel wear should be especially cautious.
The safest choice for daily brushing is a fluoride toothpaste that has been approved by dental associations. If whitening is your goal, Dr. Rush can recommend enamel-safe whitening products or in-office treatments that are both effective and protective of your oral health.
