Epigallocatechin gallate (EGCG), a compound rich in tea, has long been recognized for its diverse biological activities, including its remarkable antioxidant, anti-inflammatory, antibacterial, and anti-tumor properties. However, recent research has uncovered a new, promising application of EGCG: its role in the prevention of dental caries. This paper aims to comprehensively review the mechanisms underlying EGCG's involvement in caries development and progression, focusing on three key areas: its regulation of matrix metalloproteinases (MMPs), its inhibitory effects on Streptococcus mutans, and its promotion of dentin and enamel remineralization. Matrix metalloproteinases (MMPs) are a family of enzymes that play a crucial role in the degradation of extracellular matrix components. In the context of caries, MMPs are involved in the breakdown of tooth structure, facilitating the progression of the disease. EGCG has been shown to regulate MMP activity, thus potentially slowing down the destructive process associated with caries. By inhibiting MMPs, EGCG could help maintain the integrity of tooth structure and prevent further damage. Another significant aspect of EGCG's caries-preventive action is its inhibitory effect on Streptococcus mutans, a bacterium that plays a key role in caries development. S. mutans produces acids that erode tooth enamel, leading to caries formation. EGCG has been found to inhibit the growth of S. mutans and reduce its acid production, thereby reducing the risk of caries development. Lastly, EGCG promotes the remineralization of dentin and enamel. Remineralization is the process of depositing calcium and phosphate ions back into tooth structure, helping to repair damage caused by caries. EGCG has been shown to enhance this process, potentially leading to the reversal of early caries lesions and the restoration of tooth health.
