Summer means longer evenings, BBQ, apéros and one more round of cocktails. But while you're enjoying a cold beer or a spritz in the sun, your teeth are dealing with the consequences. Alcohol affects your oral health in more ways than you might expect and it's not just about sugar.

Dry Mouth: The Hidden Problem
Alcohol is a diuretic. It dehydrates you. But it also reduces saliva production, and that matters more than most people realise. Saliva is your mouth's natural defence system: it neutralises acids, washes away food particles and helps remineralise enamel.
When saliva flow drops, bacteria thrive. That dry, sticky feeling after a night out isn't just discomfort, it's your oral environment becoming more vulnerable to plaque build-up, bad breath and gum irritation.
Acid and Enamel Erosion
Most alcoholic drinks are acidic. Wine, prosecco, gin and tonic, cocktails with citrus, cider, sour beers. They all sit low on the pH scale. Every sip temporarily softens your enamel, and over time, repeated acid exposure wears it down. ( Lussi A, Jaeggi T. "Erosion — diagnosis and risk factors." Clinical Oral Investigations, 2008 )
White wine is often more acidic than red. Prosecco combines acidity with carbonation, which amplifies the erosive effect. And cocktails are a double hit: citrus juice for acid, syrup for sugar.
Beer is slightly less acidic, but it's not neutral. Darker ales tend to be less erosive than pale lagers or sour styles, though all beer still contributes to an acidic oral environment. ( Liguori G et al. "Erosive potential of different alcoholic beverages." Journal of Dentistry, 2019 )
Sugar: Fuel for Bacteria
Many popular drinks are loaded with sugar and not just the obvious ones. A mojito, a margarita, a rum and cola, a cider: they all deliver significant amounts of sugar directly onto your teeth. Oral bacteria feed on that sugar and produce acids as a byproduct, which further attacks enamel.
Even drinks that taste dry or bitter can contain more sugar than expected. Tonic water, for example, contains around 18g of sugar per standard serving.
Staining
Red wine is the most well-known culprit, but it's not alone. Dark beers, sangria, and cocktails with berry-based liqueurs can all contribute to surface staining over time. Tannins in red wine bind to enamel and make it easier for pigments to stick, especially when enamel is already softened by acid.
What You Can Do
You don't need to give up a summer apéro. But a few simple habits can help protect your teeth without spoiling the evening.
1. Drink water between rounds. It rinses acid and sugar from your teeth, rehydrates your mouth and supports saliva recovery. If you can, choose still water over sparkling, carbonation is mildly acidic.
2. Avoid brushing immediately after drinking. Enamel is temporarily softened by acid, and brushing too soon can cause more damage. Wait at least 30 minutes, or rinse with water first.
3. Choose lower-sugar options when possible. A glass of red wine, a spirit with soda water, or a dry beer will expose your teeth to less sugar than a cocktail loaded with syrup and juice.
4. Chewing sugar-free gum after drinking stimulates saliva flow, which helps neutralise acids and restore balance in your mouth naturally.
