Millions of people worldwide are affected by tooth decay and plaque, even those who brush their teeth regularly and visit the dentist.
Researchers are investigating a natural compound found in vegetables that may help reduce the biofilm that causes tooth decay.
This discovery could revolutionize daily oral care, providing a complementary solution to traditional hygiene practices and improving overall oral health.
While brushing, flossing, and mouthwash can remove some bacteria, stubborn biofilms often form on teeth, allowing harmful bacteria to thrive.
Scientists are exploring whether a natural compound can safely break down these biofilms, providing a low-toxicity approach to keeping teeth clean and strong.
Early laboratory results show promise, suggesting that an everyday food may offer unexpected oral health benefits.
The compound under investigation is called 3,3′-diindolylmethane (DIM), or diindolylmethane, and it occurs naturally in vegetables such as broccoli, cabbage, and Brussels sprouts.
Laboratory tests have shown that DIM can break down up to 90% of biofilms formed by Streptococcus mutans, a bacterium closely associated with tooth decay.
DIM’s natural origin and its selective effect on harmful bacteria make it a promising candidate for future dental care solutions.
S. mutans thrives in the mouth, especially in the warm, sugary environment after eating. These bacteria form a sticky layer on teeth, called a biofilm, which contributes to plaque accumulation and enamel erosion.
In laboratory tests, DIM almost completely destroyed this biofilm, preventing the bacteria from multiplying and adhering to teeth.
One of DIM’s most attractive features is its low toxicity. Because DIM occurs naturally in vegetables, it could be a safer alternative to some harsh chemicals used in dental products.
DIM’s ability to target harmful bacteria without harming healthy tissue is a key reason why scientists are so fascinated by this compound.
The study, published in the journal Antibiotics, was led by Professor Ariel Kushmaro of Ben-Gurion University of the Negev and included researchers Yifat Baruch, Karina Golberg, Robert S. Marks, Qun Sun, and Karina Yew-Hoong Gin.
If future studies confirm DIM’s effectiveness in humans, it could serve as a natural supplement to brushing and flossing.
Adding this compound to toothpaste or mouthwash could more effectively reduce plaque buildup and potentially lower the risk of tooth decay.
DIM could also benefit those who lack access to professional dental care by offering a simple, food-based approach to oral health maintenance.
Beyond dental care, DIM has also attracted attention for its potential anticancer properties. Its safety and selective antibacterial effects make it an ongoing research priority. However, human trials are needed to confirm its benefits in dental care.
While traditional oral hygiene remains crucial, DIM may one day offer additional protection. Its presence in everyday vegetables makes it a particularly attractive preventative healthcare option.
