An In-Depth Exploration of Natural and Herbal Tooth Whitening Agents: Efficacy, Safety, and Clinical Applications.

Discoloration refers to the alteration of the original color of an object, resulting in an unpleasant or damaged appearance. Tooth discoloration can occur due to trauma, residual intracanal medicaments or obturating materials, as well as extrinsic factors such as tea, coffee, and chromogenic bacteria. To reduce or eliminate discoloration, whether in a vital or non-vital tooth, several treatment options are available. The simplest and most cost-effective treatment is bleaching. The bleaching materials used not only diminish discoloration but also have side effects, including compromised tooth strength and cervical resorption. To mitigate these side effects, natural products have been developed, tested, and refined. This review article emphasizes various bleaching procedures, the mechanisms of action, and the effectiveness of natural bleaching agents.
