### Activated Charcoal for Teeth Whitening: Benefits, Risks, and Alternatives Activated charcoal is a fine black powder made by super-heating coal and other natural products. It's used in various products, including toothpastes, with claims that it can whiten teeth. But does it really work? #### Benefits Manufacturers claim that activated charcoal can help remove surface stains on teeth, leading to a brighter smile. However, there is limited scientific evidence to support these claims. #### Risks 1. **Thinning Enamel**: Prolonged use of activated charcoal toothpaste can wear down your enamel, making your teeth look more yellow as the dentin layer underneath becomes exposed. 2. **Surface Roughness**: Activated charcoal can increase the roughness of your teeth's surface, making it easier for bacteria to cling and increasing the risk of cavities and gum disease. 3. **Abrasiveness**: Tooth powders, including those with activated charcoal, can be five times more abrasive than regular toothpastes, which can damage your teeth. 4. **Not Suitable for Children**: Activated charcoal toothpastes are too abrasive for developing teeth and should not be used by children. #### Alternatives 1. **Professional Cleaning**: Regular dental cleanings by a professional can effectively remove surface stains. 2. **Whitening Toothpastes**: Toothpastes with mild abrasives and chemical agents can help remove surface stains without being too harsh on your enamel. 3. **Bleaching Treatments**: Professional bleaching treatments can reach intrinsic stains under the enamel, providing a more thorough whitening effect. 4. **Good Oral Hygiene**: Brushing twice a day, flossing, and avoiding stain-causing foods and drinks can help maintain a bright smile. Before trying activated charcoal toothpaste, consult your dentist to understand the risks and benefits.
