Red wine may be good for your teeth
More good news about red wine. According to a new study, moderate consumption of red wine may help boost your dental health and prevent cavities.
Scientists wanted to see if they could find a natural product that could inhibit production of oral biofilms—a thin, slimy film of bacteria that adheres to a surface—and dental plaque, which can lead to periodontal disease, tooth loss or other oral diseases. There are treatments for this, including antimicrobial prescriptions, but they often come with side effects, such as reduced taste and gum discoloration.
In the study, the researchers created a biofilm model of a dental plaque with five species of oral bacteria, which they placed in red wine, alcohol-free red wine, red wine with grape seed extract, water and 12 percent ethanol. After they allowed the biofilm cultures to sit in the solutions for a few minutes, the researchers found that the alcoholic and non-alcoholic red wine and the wine mixed with grape seed extract were most effective at fighting the bacteria.
Researchers said that their findings, published in the Journal of Agricultural and Food Chemistry, suggest that drinking a moderate amount of red wine could play a role in inhibiting the growth of certain bacteria associated with oral diseases. They added that grape seed extract should be further tested as a potential natural treatment for long-term dental care.
