Objective: Although professional dental whitening techniques such as composite bonding, veneers, and bleaching are widely practiced, traditional and herbal remedies offer effective, accessible, and potentially safer alternatives. These natural methods may contribute to the reduction of yellow and brown stains while minimizing adverse effects often associated with chemical procedures.

Methods: This review was conducted through systematic keyword searches including “medicinal plants,” “traditional medicine,” “tooth discoloration,” and “tooth whitening” in databases such as Web of Science, Medline, PubMed, Scopus, and Google Scholar. Relevant studies and ethnobotanical sources were reviewed to compile and synthesize the available evidence.

Results: Traditional Iranian medicine documents a variety of herbal remedies with tooth-whitening properties. These include lemon juice, turmeric, coconut oil, strawberries, orange peel, apple cider vinegar, banana peel, Persian pomegranate, licorice root, mint, wild thyme, and myrtle.

Conclusion: The tooth-whitening effects of these natural agents are attributed to multiple mechanisms, including mild abrasiveness, pigment degradation, antibacterial and anti-inflammatory actions, and direct bleaching effects. When applied consistently and appropriately, these remedies may contribute not only to the maintenance of dental aesthetics but also to improved oral health. Further clinical investigations are warranted to validate their efficacy and optimize safe usage protocols.
