Without pigments, life would lack vibrancy. The natural world presents us with a kaleidoscope of colours from the lush green grass of home to the warm, ruddy hues of an autumn forest. These colours, with few exceptions, arise from natural pigments found in living organisms. Beyond providing visual appeal, pigments fulfil essential biological functions. Among the various classes of natural pigments, carotenoids stand out for their wide distribution and diverse roles in biological systems. Lycopene a red carotenoid pigment, is abundant in tomatoes, apricots, guavas, watermelons, papayas, and pink grapefruits, with tomatoes serving as the primary source in the human diet. Notably, lycopene demonstrates a strong ability to quench singlet oxygen, making it a powerful antioxidant. Its vivid colour and lack of toxicity also make it a valuable natural food colorant. In addition to its antioxidant properties and use as a natural colorant, lycopene demonstrates considerable potential in both medical and dental fields. It has been recognized as an effective adjunctive, non-invasive therapeutic agent in the management of several oral diseases, including leukoplakia, oral submucous fibrosis, lichen planus, and oral squamous cell carcinoma. Furthermore, lycopene contributes to the preservation of periodontal health by preventing the breakdown of supporting tissues. This review highlights the mechanism of action, multifaceted role of lycopene, particularly emphasizing its preventative and therapeutic potential in managing a range of oral health conditions.
