Researchers have discovered that a natural maple compound, epicatechin gallate, can block cavity-causing bacteria, offering a safe, non-toxic alternative for oral care.
WASHINGTON: A natural compound found in maple, known as epicatechin gallate (ECG), could revolutionise the fight against tooth decay, according to a new study published in Microbiology Spectrum. The research reveals that ECG effectively blocks Streptococcus mutans, the bacteria responsible for cavities, by preventing it from forming harmful biofilms on teeth.
The compound is abundant, affordable, and non-toxic, making it a strong candidate for use in mouthwashes and other oral care products — particularly for young children who might accidentally swallow conventional formulations. Unlike traditional methods that rely on killing bacteria with alcohol or disinfectants, or using fluoride to remineralise enamel, ECG works through an antibiofilm mechanism, stopping bacteria from attaching to tooth surfaces.
The discovery originated from studies on how Listeria monocytogenes avoids biofilm formation on maple wood. Scientists isolated maple polyphenols that target sortase A, an enzyme key to bacterial attachment. Noting that sortase A in Streptococcus species is similar, the team tested ECG against S. mutans and found it binds to and inhibits the enzyme. Laboratory tests confirmed that ECG stops biofilm formation on both artificial teeth and hydroxyapatite discs, which mimic natural tooth enamel.
Lead researcher Mark Gomelsky, Ph.D., from the University of Wyoming, said the findings point to an exciting new preventive approach: “A safer alternative, such as a mouthwash containing an effective dose of an edible polyphenol, could provide protection without harmful side effects.”
With its potential to make dental care safer for children and more effective for all, this maple-derived compound could soon become a key ingredient in the next generation of oral health products.
