You just had a professional teeth whitening treatment. But you have dinner plans tonight — and there will be wine. Is that okay?
The Short Answer
It is best to avoid alcohol for at least 48 hours after whitening. This applies to wine, beer, dark spirits, and coloured cocktails — anything that could introduce staining agents to your freshly whitened teeth.
Why Alcohol Is a Problem
After whitening, your enamel pores are temporarily open and highly susceptible to staining. Alcohol, especially red wine, is both acidic and deeply pigmented. It also causes dehydration, which reduces saliva production — your natural defence against staining.
What About White Wine and Spirits?
While lighter-coloured drinks are less likely to cause staining, they are still acidic. Acid softens enamel and makes it more vulnerable. For the first 48 hours after whitening, water is always the safest choice.
The White Diet After Whitening
The general rule for the first 48 hours is a "white diet" — pale-coloured foods and beverages only: white rice, chicken, fish, bread, milk, and clear liquids. After 48 hours, your enamel pores will close and you can gradually reintroduce other foods and drinks.
