What Not to Eat and Drink After Teeth Whitening


A bright, white smile can be a wonderful confidence booster, and teeth whitening treatments have made this more attainable. But the journey to a dazzling smile doesn’t end when you leave a dental clinic. The aftermath of teeth whitening is critical, as what you consume can significantly impact the longevity of the results.

This guide will help you identify which foods and drinks to avoid to maintain the newfound brilliance of your teeth. Choosing the proper diet can be challenging, but with the right information, you can make informed choices that will keep your smile bright. Read on to learn how to best care for your whitened teeth.

Dark-Coloured Foods

Following your dentist appointment for teeth whitening, it’s crucial to be mindful of what you eat—especially in the first 24 hours. Dark-coloured foods are often the culprits behind tooth discolouration. To maintain the results of your treatment, avoiding certain foods that can easily stain your teeth is advisable. These include:

Sugar-Loaded Treats

After a teeth whitening procedure, it’s not just the colour of what you eat that matters but also the sugar content. Cookies, cakes, and ice cream contain refined sugars, which attract bacteria, including those that cause tooth decay and staining. These sugary delights not only attract harmful bacteria but also contribute to the weakening of your tooth enamel.

Since your teeth tend to be more sensitive and porous immediately following a whitening treatment, it’s wise to steer clear of these sugar-laden treats for a while.

Citrus Fruits

Acidity in citrus fruits weakens tooth enamel

Grapefruits, lemons, limes, and oranges are known for their vitamin content, but if you have just had your teeth whitened, they can pose a challenge. The high acidity in these fruits can exacerbate the weakening of tooth enamel. This not only heightens sensitivity to temperature extremes in foods and drinks; it also increases the susceptibility of your teeth to staining. Considering this, it’s best to limit your intake of these acidic fruits following a teeth whitening procedure to maintain the strength and appearance of your teeth.

Foods with Colourants or Dyes

After you visit the dentist’s office for teeth whitening, pay special attention to foods and beverages containing colourants or dyes. Sports drinks, popsicles, and other products contain artificial and natural additives. Quickly checking the ingredients label can help you identify these items.

While adhering to this dietary guideline might seem restrictive initially, it’s a small trade-off for the benefits your smile will reap. To stay on the safe side, opt for ‘whiter’ foods and light-coloured vegetables and fruits. Additionally, prioritize drinking water, using it to replace coloured beverages as much as possible.

For the first 48 hours post-whitening, limiting exposure to the items mentioned is crucial. But if you consume them, brush and floss immediately to prevent new stains. Scheduling dental cleanings and exams with your dentist in Waterloo can also play a key role in ensuring the longevity of your whitening results.


Turmeric, a plant-based spice renowned for its vibrant yellow colour, is notorious for its staining capabilities. Whether it’s clothing or teeth, turmeric stains are often stubborn and challenging to remove. In the context of teeth whitening, it’s essential to avoid this spice following your procedure. Its intense pigmentation can quickly counteract the effects of teeth whitening treatments.

Teas and Coffee

Many people cherish their daily cups of coffee and tea, but these beloved beverages pose a risk to your newly whitened teeth. Coffee, with its potent and dark composition, is particularly known for causing stains. If giving up coffee seems daunting, consider adding milk to lessen its staining potential.

Tea, especially dark varieties, can be even more of a culprit in staining teeth than coffee. The tannins in tea contribute significantly to discolouration, making it advisable to limit your tea intake, particularly right after your teeth whitening procedure.

Dark Sauces

Be cautious about consuming dark-coloured sauces and condiments post-teeth whitening. Avoid staples like soy sauce, mustard, and ketchup, known for their deep hues, as they can easily stain your newly brightened teeth. A simple rule of thumb to determine whether a sauce or condiment might be risky is to think about its potential to stain a white t-shirt. If it’s likely to leave a mark on fabric, it indicates that it could have a similar effect on your teeth.


Stains can result from drinking wine

Wine, particularly red wine, is a beverage to approach with caution after teeth whitening. Both red and white wines have acidic properties that can weaken tooth enamel, rendering your teeth more susceptible to stains. This vulnerability isn’t limited to the wine but extends to potential staining from other foods. Being mindful of your wine consumption post-whitening can help maintain the brightness and health of your teeth.

Fizzy Soft Drinks

Avoid consuming fizzy soft drinks in the 48 hours following your teeth whitening treatment. These beverages are typically high in sugar, colour additives, and acidity—a combination that’s particularly harmful to your newly whitened teeth. The acidic content can erode tooth enamel, while the colour additives contribute to surface staining.

Post-Teeth Whitening: Foods to Enjoy

After your advanced teeth whitening treatment, there are still numerous delicious options that your family dentist would approve of. These include:

To preserve the bright, white radiance of your smile after teeth whitening, being mindful of your dietary choices is essential. Avoiding foods and beverages known for their staining properties is a key step in this process. Combine this cautious approach with robust oral health practices for a stunning and healthy smile. Remember, regular dental check-ups are crucial, so don’t hesitate to find a dentist for ongoing care and advice.
