Part 6/12:
In a practical experiment, a host tested whether charcoal toothpaste truly whitened teeth. Over three weeks, he used a split-mouth approach—one side with charcoal toothpaste and the other with regular toothpaste. Baseline dental scans and subsequent checkups revealed negligible differences in teeth shade or cleanliness.
Dentists concur that while charcoal can remove surface stains temporarily due to its abrasiveness, it does not alter the underlying color of teeth. Moreover, long-term use could damage enamel, making the teeth more sensitive.
