Most of the world’s population either chronically suffers from plaque and dental cavities or will develop them at some point in their lives. Toothpastes, mouthwashes, and regular checkups do their part, but more can always be done. Now, Ben-Gurion University of the Negev scientists and their colleagues at Sichuan University and the National University of Singapore have discovered that 3,3′-Diindolylmethane (DIM), a naturally occurring molecule also known as bisindole, reduces by 90% the biofilms that produce plaque and cavities. The molecule is also found to have anti-carcinogenic properties.
Their findings were published earlier this month in the journal Antibiotics.
Your mouth is a great reservoir for bacteria such as S. mutans, which is believed to be one of the primary actors in dental cavities. After you eat, S. mutans grows in the moist and sugary atmosphere of your mouth in a biofilm that coats your teeth. Biofilm generates plaque, attacks enamel and causes cavities. The scientists found that the bisindole (DIM) disrupted that biofilm by 90% and therefore the bacterium was not given a chance to grow.
