These natural methods may contribute to the reduction of yellow and brown stains while minimizing adverse effects often associated with chemical procedures.</span></span></p> <p data-end="875" data-start="508" style="text-align: justify;"><span style="font-size:14px;"><span style="font-family:Times New Roman;"><strong data-end="520" data-start="508">Methods:</strong>&nbsp;This review was conducted through systematic keyword searches including &ldquo;medicinal plants,&rdquo; &ldquo;traditional medicine,&rdquo; &ldquo;tooth discoloration,&rdquo; and &ldquo;tooth whitening&rdquo; 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.</span></span></p> <p data-end="1171" data-start="877" style="text-align: justify;"><span style="font-size:14px;"><span style="font-family:Times New Roman;"><strong data-end="889" data-start="877">Results:</strong>&nbsp;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.</span></span></p> <p data-end="1674" data-start="1173" style="text-align: justify;"><span style="font-size:14px;"><span style="font-family:Times New Roman;"><strong data-end="1188" data-start="1173">Conclusion:</strong>&nbsp;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.</span></span></p> <div style="text-align: justify;"></div> Tooth, Tooth yellowness, Whitening, Beauty, Traditional medicine 84 88 http://pbp.medilam.ac.ir/browse.php?a_code=A-10-423-2&slc_lang=fa&sid=1 Mohammad Jafari Heydarlou dr.jafarimo@yahoo.com 10031947532846005551 10031947532846005551 No Department of Oral and Maxillofacial Disease, School of Dentistry, Urmia University of Medical Sciences, Urmia, Iran Ahed J Alkhatib ajalkhatib@just.edu.jo 10031947532846005552 10031947532846005552 Yes Department of Forensic Science and Toxicology, Faculty of Medicine, Jordan University of Science and Technology, Jordan
