What to Avoid Eating and Drinking After a Teeth Whitening Treatment

Acorn Dental Health • 4 August 2021

Whitening your teeth will help your smile to shine and it removes the years of yellowing and dullness that can occur over time. However, if you don’t take care of your teeth after having them whitened, you will end up in the same position again. The first 48 hours after whitening, your teeth are particularly vulnerable so it's essential that you take care of what you eat and drink.


It’s worth taking the time to be careful after you’ve spent money on perfecting your smile. Even so, it’s only a few days and that will make all the difference in how long the whitening process lasts. If you eat something too acidic or something with colouring at an early stage, it will destroy the careful work the dentist has achieved. You’ll lose your progress and no one wants that!

Here’s what to avoid after you’ve had your teeth whitened.


Acidic Foods and Drinks

Fruit juice and alcohol can be considered acidic and can eat away at the enamel of your teeth, ruining them. You should also avoid fizzy drinks or anything else with a lot of sugar in it. Acidic citrus fruits are also off the list of foods you should eat.


Foods with Colourants and Additives

Anything that has strong colouring in it can affect your teeth and can fade the whitening. This includes beets, red wine, pasta sauce, BBQ sauce, etc.


Tea and Coffee

Both tea and coffee have very strong tinting properties and can rapidly discolour your teeth again. You should try to avoid them at all costs, but if you do drink them, consider using a straw to bypass your teeth. In fact, caffeine in general should be avoided, including dark chocolate, as it will stain, too.

After the first few days, you can begin to eat and drink these things again, but they’re not the best options for your teeth over the long term. Sugar is not only acidic, but it will also cause tooth decay over time, so it’s not only about preventing stains. You want to keep your teeth as healthy as possible to avoid losing them in the future.


Keep in mind that teeth whitening is not a permanent solution and eventually your teeth will become dull once more. You can have touch up treatments over time to help them stay bright and pretty, though. The whitening will last longer if you’ve taken the time to be careful with them by carefully considering what you eat and drink.
