Wine, with its strong pigments and natural acidity, isn’t exactly a loyal friend to our teeth. White wine, in particular, is highly acidic, with a pH between 3 and 4, and can significantly contribute to the demineralization of dental tissues. This makes the tooth surface more porous – and therefore more vulnerable to the bacteria that cause cavities, to acidic substances that intensify dental erosion, and to the chromogenic compounds found in wine itself or in the foods you eat afterward.
So drinking wine frequently – especially between meals – can cause permanent damage to the enamel and significantly increase tooth sensitivity. In addition to wine’s acidity, there’s also the astringent effect of certain polyphenols, such as tannins, and the dehydrating action of alcohol, which contributes to dry mouth.
But not all wine is out to get us. Fortunately, its drawbacks come with a few noteworthy benefits. Wine – red wine in particular – has a remarkable bactericidal effect against Streptococcus species. It also inhibits their ability to adhere to tooth enamel, which in turn reduces the risk of cavities. Some studies even suggest that wine drinkers show a lower incidence of gingivitis and periodontal disease.
“THE SECRETS TO A HEALTHY APERITIVO”
We all know that aperitivo time isn’t exactly diet-friendly – but it is universally loved. So what should you choose if you want to enjoy it without neglecting your oral health? Opt for red wine, unsweetened juices, or low-sugar long drinks. Pair them with black olives, cheese, salmon, anchovies, walnuts, or fresh crudités. Then finish with a bit of cheese – an excellent calcium-rich “antidote” that helps remineralize dental tissues.
A few sprays of Cariex® right after a glass of wine immediately raise the pH level, helping prevent cavities, dental erosion, and tooth staining.
