Can Red Wine And Beer Fight Cavities?

Few people in the world are immune to cavities. In fact, 60 to 90 percent of the world’s population have cavities, periodontal disease, and tooth loss. Can beer and red wine help combat dental disease? We know that red wine has certain health benefits such as lowering cholesterol and protecting your heart. Beer also has health benefits. Beer–especially darker brews–contains natural antioxidants which can help reverse cellular damage, and help prevent heart disease. It also contains iron which carries oxygen from your lungs to other parts of your body, as well as other vitamins that can help rebuild muscle. Microbrews contain more hops, which contain polyphenols, which help kill viruses, lower cholesterol, and fight cancer. New research indicates that extracts from hop leaves and red wine both contain agents that can help fight oral bacteria.

Oral Bacteria And Dental Disease

Our oral cavity harbors thousands of bacteria, some good and some bad. The two most common harmful bacteria found in the oral cavity are streptococcus mutans and porphyromonas gingivalis.

Porphyromonas gingivalis is a harmful bacteria that is not normally present in the mouth of healthy individuals, but if it develops it can lead to periodontal disease and tooth loss.

Streptococcus mutans is the bacteria that feed on the sugars and starches left in your mouth after you eat. As this bacterium interacts with the sugars and starches, acids that eat away enamel are produced, making these bacteria the major cause of tooth decay.

Colonies of bacteria form biofilms, a thick, sticky substance that forms on your teeth. Left untreated the biofilm hardens into plaque which hardens into tartar, a cement-like substance. Plaque and tartar are harmful to your teeth and gums and can lead to periodontitis and tooth loss.

Hop Leaves fight Oral Bacteria 

Recent research indicates that both beer and red wine can be beneficial to dental health by fighting harmful bacteria.


Hops give beer its bitter taste and is more prominent in darker brews.  According to the ACS’ Journal of Agricultural and Food Chemistry, new research discovered that a part of hops that is not used in beer contains antioxidants that may fight cavities and periodontal disease. The extracts from hop leaves contain antioxidant polyphenols which stop oral disease-causing bacteria from sticking to surfaces, while also preventing the release of certain bacterial toxins. Hops leaves are also high in proanthocyanidins, healthful antioxidants. Bracts (hop leaves) are normally discarded, but with the nearly 2,300 tons of hops harvested in the U.S. annually, large amounts may be potentially available to use for disease fighting dental applications.


Research indicates that red wine and grape seed extract can help slow the growth of harmful oral bacteria.  Cultures of oral bacteria were cultivated, in vitro, as biofilm. The biofilms were then dipped in a variety of liquids including red wine, non-alcoholic red wine, red wine mixed with grape seed extract, and a water and ethanol mixture. The red wine, non-alcoholic red wine, and the wine mixed with grape seed extract were the most effective in eliminating the biofilm.

As people get together to socialize with friends and family during the summer months, they can take solace in the fact that a glass of wine can be beneficial to their dental health. Both beer and wine each have several health benefits. However, you should also remember… everything in moderation. Too much wine can help increase decay due to wine’s acidity. The longer you keep wine in contact with your teeth the more chance of enamel erosion, so don’t swish, just sip. Both red and white wine can increase tooth stains. When finished drinking your glass of wine, rinse with water to wash away any residual effects. Tooth enamel can be softened by exposure to acids, so do not brush your teeth too soon after drinking wine.
