A groundbreaking study conducted by Israeli researchers has revealed that coffee contains natural compounds capable of reducing bad breath, potentially leading to new oral care products like mouthwashes, breath fresheners, and chewing gum designed to keep your breath fresh for longer.
Dr. Mel Rosenberg, a renowned expert in oral health from Tel Aviv University, stumbled upon this surprising discovery during his experiments. For years, it was commonly believed that coffee worsened bad breath, but the research showed otherwise. When coffee is mixed with saliva, it can actually dehydrate and ferment the mouth, creating odor-causing substances.
In their experiment, Rosenberg’s team tested two local Israeli coffees and a "Nestlé" instant coffee in glass tubes filled with saliva. Their initial hypothesis was that the combination would produce foul-smelling gases. However, the results were completely unexpected. The coffee significantly reduced the formation of odorous compounds, with some tests showing a reduction of up to 90%.
“We assumed coffee caused bad breath, but through this unique brewing process, we found that certain components in coffee actually suppress it,†said Rosenberg.
According to scientists, bad breath is a common issue, even among healthy individuals who wake up with an unpleasant morning breath. The back of the tongue and the areas around the gums are hotspots for bacterial growth, which produces volatile sulfur compounds responsible for bad odors. Foods like garlic and onions can make the problem worse, as their compounds are absorbed into the bloodstream and exhaled through the lungs.
Rosenberg is now working on isolating the specific compounds in coffee that help reduce bad breath. He believes these ingredients could prevent plaque buildup and tackle bad breath at its source. This could lead to a new generation of oral care products that go beyond masking the smell, offering a more effective solution than traditional mint-based alternatives.
Unlike conventional mouthwashes and chewing gums that only provide temporary relief, coffee-based products may offer a long-term solution. Researchers hope this discovery will pave the way for innovative products that improve oral hygiene and enhance daily freshness.
