How Long After Teeth Whitening Can I Eat And Drink?

A sparkling white smile can significantly boost your confidence, and tooth whitening is one of the most popular ways to achieve it. However, many patients have questions about their diet post-procedure: “How long after teeth whitening can I eat normally?”

The 48-hour window

After a whitening procedure, your teeth are more susceptible to staining for about 48 hours. This period is often referred to as the “white diet” phase, as it’s recommended to avoid any food or drink that could stain a white shirt. Consuming the wrong food during this window can undermine your whitening results.

Does it work for all types of stains?

Teeth whitening is a common and effective way to improve the appearance of teeth and remove stains. However, it does not work for all types of stains. Whitening may not completely remove stains that come from genetics and some medical conditions. Teeth whitening in North York is most effective at removing surface stains caused by smoking, tea, coffee, red wine, and certain foods. For more severe staining, multiple professional teeth whitening procedures may be necessary.

When can you drink normally?

Walking out of the dentist’s office after a tooth bleaching procedure, you’ll likely be flashing your pearly whites at every mirror you pass by. However, in those first critical hours post-treatment, you may wonder, “How soon can I drink normally again after teeth whitening?”

Tooth bleaching procedures open up the pores of your teeth, making them more susceptible to staining. Therefore, for about 48 hours after your procedure, avoid consuming any food or drink that could leave a stain on a white shirt. This means avoiding beverages like coffee, tea, red wine, and cola. 

Staying hydrated

What about water? You can, and indeed should, drink water immediately after your teeth whitening procedure. Staying hydrated is essential, and water can help rinse away any remaining whitening solution.


After the initial 48-hour period, you can gradually reintroduce your regular beverages into your diet. However, remember that frequent consumption of dark beverages can lead to renewed staining over time. Keeping them to a minimum can help maintain your sparkling smile longer. 

What to avoid

After your teeth whitening procedure, during the 48-hour window, you should avoid taking:

  • Dark-coloured beverages: This includes coffee, tea, red wine, dark sodas, and even certain fruit juices such as grape and cranberry. If you must have these drinks, consider using a straw to limit their contact with your teeth.

  • Foods with dark pigmentation: For the first 48 hours after the whitening procedure, avoid dark berries, chocolates, dark sauces (soy, tomato, curry), and any heavily coloured food.

  • Acidic foods and beverages: Citrus fruits, vinegar, and other acidic foods can make your teeth more porous and enhance staining.

  • Smoking: If you’re a smoker, avoid cigarettes for at least 48 hours post-whitening. The nicotine and tar in cigarettes can cause significant staining.

After adhering to the “white diet” for 48 hours post-teeth whitening treatment, you can generally return to eating as usual. However, bear in mind that to maintain your newly brightened smile, it’s wise to consume staining foods and beverages in moderation.

Cost of teeth whitening in North York

Professional teeth whitening cost is typically higher than at-home whitening kits. However, it is safer and can deliver much better results in less time. If you’re looking for a fast, safe way to whiten your teeth, in-office whitening is a great option to consider.

In-office tooth whitening at a dentist’s office can range between $500 and $1000. For best results, we recommend speaking with a dental professional to discuss the best whitening option for your specific needs and budget.

Maintaining the results of tooth whitening

Maintaining your brilliant result after the procedure requires: 

  • Good oral hygiene habits

  • Skipping some beverages and meals that can discolour teeth

  • Regular brushing and flossing

  • Avoid smoking and drinking coffee, tea, red wine, and other products that can stain teeth. 

  • Limiting sugary and acidic foods and drinks, as these can erode enamel and make teeth appear yellow. 

  • Regular professional cleanings and checkups can also help maintain the results of the teeth bleaching procedure by removing any plaque or tartar buildup that can darken teeth. 

By following these tips, you can preserve the whitening results and enjoy a brighter smile for longer.


Teeth whitening can transform your smile, but what you consume post-procedure can make all the difference in the longevity of your results. By sticking to the “white diet” for 48 hours post-whitening, and then consuming potentially staining substances in moderation thereafter, you can maintain your sparkly smile longer. Remember, a beautiful smile is a collaboration between effective professional whitening and thoughtful aftercare.
