How will Dry January help my mouth and teeth?

Are you taking part in Dry January this year? Or perhaps you’re thinking about reducing your alcohol intake more generally. If so, your mouth, teeth, and overall health will thank you.

It may come as no surprise that alcohol can have a negative impact on both oral and general health. By cutting down, or cutting it out altogether, you can lower your risk of a range of health concerns:

🍷 Improved Gum Health: Alcohol reduces saliva production, which plays a vital role in neutralising acids and helping to remineralise tooth enamel. A dry mouth also encourages harmful bacteria, increasing the risk of gum disease.

🍷 Reduced Risk of Mouth Cancer: Alcohol consumption, particularly when combined with smoking, is a major risk factor for mouth cancer. Excessive drinking is linked to around one in every three cases.

🍷 Prevention of Tooth Decay: Many alcoholic drinks contain sugars and acids that can contribute to tooth decay, and even when they don’t, the mixers often do.

🍷 Fresher Breath: Alcohol dries out the mouth, creating the perfect environment for odour-causing bacteria. Cutting back can help keep your breath fresher.

🍷 Less Staining: Certain drinks, especially red wine, can stain teeth and dull your smile.

Whether you’re fully embracing Dry January or simply making small changes, your teeth, gums, and overall health will benefit from this positive step in 2026
