What to Eat After Teeth Whitening: The White Diet

A Young Patient Learning the Correct Method to Brush Teeth

A teeth whitening process at your dentist’s office can offer you a brighter smile than over-the-counter whitening strips can.

After spending the time, money, and effort to whiten your teeth, you want to be able to enjoy the results for as long as possible. Because newly whitened teeth are more sensitive to discoloration, it’s critical to make smart food choices in the two or three days following a whitening treatment.

Chemical agents are used in whitening products to penetrate the tooth enamel and break down stains. Carbamide peroxide or hydrogen peroxide is the most common chemical agent used to whiten teeth. Carbamide peroxide breaks down into hydrogen peroxide and urea when used as a tooth whitening agent. The active ingredient in whitening is hydrogen peroxide. Teeth become permeable after coming into contact with these chemicals.

This is a transitory state, as the bleaching agents continue to enter the enamel and whiten for another 24 hours following a whitening session. Teeth are particularly prone to staining during this period, so avoid foods, beverages, or mouthwashes that contain dyes or are dark in colour and stick to things that won’t cause discoloration.

A short-term diet consisting of white and light-coloured foods and beverages is known as the “White Diet.”

Avoiding Certain Foods and Drinks After Teeth Whitening

Natural pigments or artificial colours in the foods and beverages listed below might pile up over time and cause discoloration.

You don’t have to avoid these foods indefinitely. Because your teeth are most sensitive during the first few days after whitening, many dentists advise merely avoiding certain meals for around two days.

1. Drinking wine

Both red and white wines can be damaging to your teeth’ colour and enamel. Red wine has a high acidity level, and the dark hue makes it stain-prone. White wine, despite its lighter hue, can also eat away at the

2. Tea & Coffee

Although it may be difficult to give up coffee or tea for a few days, avoiding these beverages will help you prevent one of the most common sources of stains.

Coffee and tea contain tannins, which can darken the colour of your teeth over time. When your teeth are at their most porous after a professional whitening, tannins can discolour significantly faster.

After you’ve had your teeth whitened, you should avoid drinking coffee and tea for a few days. If you really must have your morning coffee, drink it via a straw to avoid direct contact with your teeth.

3. Non-alcoholic beverages

If it fizzes, you should probably avoid it. Carbonated beverages include a lot of sugar and acid, which can wear down dental enamel. Surface stains can also be caused by dark-coloured colas. Even if you aren’t following the White Diet, avoiding soft drinks can help you have healthier, brighter teeth.

4. Chocolate and candy

Sugars that have been refined can cause decay, erosion, and discolouration, particularly if your teeth are sensitive after whitening. After your surgery, stay away from chocolate and artificially coloured candy.

5. Dark Fruits

Pigments found in dark-coloured fruits can discolour your teeth. Enamel degradation can be exacerbated if some fruit is very acidic. Fruits with dark juices, such as raspberries, cherries, pomegranates, blackberries, and blueberries, should be avoided. Avoid juices that contain these fruits as well.

However, don’t eliminate healthful fruits from your diet for too long—safe it’s to reintroduce your favourites 48 hours after whitening.

Foods and Drinks to Consume Following Teeth Whitening

Now that you know what foods to avoid, here are some delicious dishes to enjoy after your teeth have been whitened. These are primarily white-coloured meals with low acidity and are free of dyes and chemicals that might cause stains, as the name implies.

1. Fish, Chicken, & Tofu

In general, light, lean proteins are good for you, and they’re even better after you’ve had your teeth whitened. To go with your protein, avoid any bright seasonings or sauces and instead opt for white sauces.

2. Rice, Bread, & Pasta

On the White Diet, most grains are fine. However, watch out for bread and pasta that contains molasses or food colouring, as these are sometimes used to give bread and pasta an artificially darker appearance, which can stain your teeth.

3. White Cheese & Yogurt

Artificially coloured cheeses and sweet, flavoured yogurts should be avoided. This diet works best with white cheeses and simple yogurt.

4. Fresh Fruits & Vegetables

The White Diet emphasizes light-coloured fruits and vegetables. Fruits (such as pears, bananas, and apples) and vegetables (such as cauliflower, potatoes, and mushrooms) are not only wonderful for your health, but they are also good for your teeth!

5. Water

Water is the finest beverage for hydration, oral health, and brightening your smile. Water will not stain your teeth or wear down your enamel, therefore it should be your primary beverage option on the White Diet.

Other Options for Teeth Protection After Whitening

Stop smoking

Nicotine, whether in the form of a cigarette, chewing tobacco, or an e-cigarette, can produce enamel discoloration that is difficult to erase. Not only will quitting tobacco improve your teeth, but it will also improve your overall oral health.

Dental cleanings and checkups on a regular basis

Teeth whitening should not be your only reason for seeing the dentist; regular examinations and dental cleanings should be combined with whitening procedures to keep your smile healthy.


Teeth whitening results are unique to each person, and the long-term consequences vary depending on factors such as age, genetics, and personal habits. To extend the results of teeth whitening, avoid foods and beverages that can discolour teeth, practise proper oral hygiene, and schedule regular dental cleanings and examinations with your dentist. If you’re thinking about getting your teeth whitened, remember that the best results come from doing your whitening procedure following a professional cleaning!
