Green Tea (Camellia Sinensis) in Dentistry: Exploring Green Tea’s Antioxidant and Antimicrobial Benefits for Salivary Gland Disease and Oral Hygiene

Green tea (Camellia sinensis) has gained significant attention in dentistry due to its potent antioxidant and antimicrobial properties. Rich in polyphenols, particularly catechins such as epigallocatechin gallate (EGCG), green tea plays a crucial role in maintaining oral health by reducing oxidative stress and preventing microbial infections. Its antioxidant properties help in combating free radicals, thereby protecting salivary glands from inflammation and dysfunction. Additionally, green tea exhibits strong antimicrobial activity against various oral pathogens, including Streptococcus mutans and Porphyromonas gingivalis, which are responsible for dental caries and periodontal diseases. In salivary gland disorders, green tea has shown promise in alleviating conditions such as xerostomia (dry mouth) by enhancing salivary flow and reducing bacterial colonization. Its anti-inflammatory effects further aid in managing sialadenitis and other glandular infections. Moreover, green tea-based mouth rinses and toothpaste formulations have demonstrated efficacy in reducing plaque accumulation and improving overall oral hygiene. With its natural bioactive compounds, green tea serves as a complementary therapeutic approach in dentistry, offering a safe and effective alternative to synthetic antimicrobial agents. Future research should focus on optimizing its formulations for enhanced clinical applications. This review highlights the potential of green tea in maintaining salivary gland health and promoting oral hygiene, reinforcing its role as a beneficial natural adjunct in dental care.
