This review article explores the application of nanotechnology in toothpaste, focusing on the benefits and uses of various nanomaterials. The authors discuss how nanoparticles, such as hydroxyapatite (HAP), titanium dioxide (TiO2), zinc oxide (ZnO), silver, and gold, are incorporated into toothpaste to enhance its efficacy in preventing dental decay, remineralizing teeth, reducing hypersensitivity, and improving whitening. The article highlights the advantages of using nanomaterials, including their ability to improve the stability, solubility, and release of active ingredients, as well as their potential to reduce side effects compared to traditional toothpaste components. The review also examines the clinical applications of these nanoparticles, such as their role in anti-bacterial, whitening, hypersensitivity, and remineralizing agents. Additionally, the article discusses the importance of nanotechnology in preventing dental diseases and the need for high-quality toothpaste to improve oral health care. The authors conclude by emphasizing the potential of nanotechnology in developing advanced toothpaste formulations that can effectively combat dental issues while enhancing patient compliance and satisfaction.This review article explores the application of nanotechnology in toothpaste, focusing on the benefits and uses of various nanomaterials.
