Alcohol consumption can lead to the erosion and loss of teeth, heighten sensitivity, and trigger a range of oral health issues. An orthopedic dentist and founder of the Asteavita clinic, Evgenia Boytsova, highlighted these concerns in conversations with socialbites.ca.
The core reason is that ethanol, or ethyl alcohol, found in alcoholic beverages, can wash away calcium—the essential mineral that builds and strengthens hard dental tissues.
As a result, teeth lose their resilience, decay accelerates, and sensitivity increases. In addition, alcohol can accelerate overall tooth decay. It also reduces the levels of minerals like iron and zinc in the body, which are important for maintaining healthy teeth, according to the expert, Evgenia Boytsova.
Alcohol also disrupts the oral microflora. When alcohol is consumed in excess, the mouth tends to become more acidic, creating favorable conditions for harmful bacteria to multiply. An acidic environment can initiate pathological changes in enamel, the root, the periodontal ligaments, the gums, and the jawbone socket. The most noticeable signs include the appearance of plaque as the microflora shifts and enamel darkens. Plaque formation often leads to gingivitis, which is inflammation of the gums and can progress to periodontitis. This progression can make teeth looser, cause discomfort and bleeding, and increase the likelihood of intermittent tooth loss, cautioned Boytsova.
She also noted that alcohol disrupts the oral microflora and can cause dehydration, leading to dry mouth. A dry mouth reduces saliva, which normally buffers acids and helps protect teeth. Additionally, alcoholic drinks often contain high amounts of sugar, feeding harmful microorganisms in the mouth.
Over time, these organisms release acids that wear away tooth enamel. Beverages with colorants can stain both natural teeth and existing restorations. Carbonated and effervescent drinks can irritate tooth surfaces, elevate dental hypersensitivity, and reduce overall tooth durability, the dentist emphasized.
Beyond direct effects on teeth, lifestyle factors connected with drinking—such as poor dietary choices and inconsistent oral hygiene—can compound the risk. Regular brushing with fluoride toothpaste, flossing, and routine dental checkups remain essential for keeping teeth healthier in spite of occasional alcohol use. Dental professionals advise drinking water between alcoholic beverages, using a straw for acidic drinks, and choosing non-sugary options when possible to minimize enamel erosion and plaque buildup. Individuals should prioritize moderation, read nutrition labels, and seek guidance from their dental care providers on personalized strategies to preserve oral health while enjoying social occasions.
In summary, alcohol can contribute to mineral loss, dryness, microbial imbalance, staining, and weakened enamel, all of which raise the risk of decay and gum disease. The consequences extend beyond aesthetics and comfort, potentially affecting long-term tooth retention. A cautious approach to alcohol consumption, combined with solid daily oral care, offers the best defense against these oral health challenges.
