A whitening treatment can give you a dazzling smile. But, it’s key to care for your teeth after. For the first 48 hours, your teeth are especially vulnerable to staining. To keep your new smile bright, follow a “white diet” and avoid certain foods and drinks. This article will guide you on what you can and cannot eat after teeth whitening.

Why Follow a White Diet?

After Teeth whitening, your teeth become slightly porous. This means they can absorb colours from foods and drinks more easily. By eating a white diet, you limit the dyes and pigments that touch your teeth. This helps keep your bright smile.

Foods and Drinks to Avoid

Here are some foods and drinks you should avoid for the first 48 hours after whitening:

Coffee and Tea

Coffee and tea are rich in tannins, which can stain your teeth. If you must drink them, add a lot of milk to reduce their staining effects. Try to limit your intake to no more than two cups a day.


Both red and white wines are acidic. Red wine has dark pigments. They can stain your teeth. White wine’s acidity can weaken your enamel, making your teeth more susceptible to other stains.

Fizzy Drinks

Fizzy drinks are highly acidic and often contain artificial colours. Avoid these beverages to protect your enamel and prevent staining.

Fruit Juices

Fruit juices are acidic. This is especially true for those from dark fruits like blueberries and blackberries. They are also pigmented. These can stain your teeth, so it’s best to avoid them.

Dark Sauces

Soy sauce, balsamic vinegar, and other dark sauces can stain your teeth. Avoid these for the first 48 hours.

Dark Fruits

Fruits like blueberries, cherries, and blackberries are rich in pigments that can stain your teeth. Stay away from these fruits and their juices.


Curry can stain your teeth just like it can stain your pots and pans. Avoid this food to keep your smile bright.

Sweets and Chocolate

Sweets and chocolate can stain your teeth, especially those with artificial colours. It’s best to skip these treats for a couple of days.


Tobacco products can severely stain your teeth. Avoid smoking or using any tobacco products after your whitening treatment.

Foods and Drinks You Can Have

Now that you know what to avoid, here are some safe foods and drinks for your post-whitening diet:

Chicken and Turkey

These meats are light in colour and acid-free, making them perfect for your white diet. They are also healthy and nutritious.


Stick to white fish like cod or haddock. Avoid darker fish which can have pigments that stain.

Rice, Bread, and Pasta

These staples are safe to eat, but be cautious of any sauces. Choose white bread and plain pasta without coloured sauces.

White Cheese and Yogurt

White cheese and plain yogurt are great choices. Avoid any with added colours or flavours.

Fresh Fruits and Vegetables

Light-coloured fruits like bananas and pears, and vegetables like cauliflower and potatoes, are safe to eat. They are healthy and won’t stain your teeth.

Egg Whites

Egg whites are a great protein source. Avoid the yolks as they have colour that can stain.


Peel the skin off and eat only the white part. Mashed potatoes are a good option.

White Bread

Choose white bread and remove the crust to be extra safe.


Bananas are light in colour and make a safe, easy snack.


Plain, white yogurt is ideal. Avoid any with added colours or flavours.


Enjoy a bowl of plain porridge with milk. If you need to sweeten it, use a sweetener instead of sugar.


Water is the best drink for your teeth. It helps wash away food particles and doesn’t stain. Make it your go-to beverage.

Other Tips to Protect Your Teeth

Quit Smoking

Nicotine can stain your teeth and harm your oral health. Quitting smoking is beneficial for both your teeth and your overall health.

Regular Dental Checkups

Regular dental checkups and cleanings can help maintain your smile. Combine these with your whitening treatments for the best results.

Use a Straw

When drinking anything other than water, use a straw. This reduces contact with your teeth and helps prevent staining.


Maintaining a bright smile after teeth whitening is easy if you follow the white diet. Avoid foods and drinks that can stain your teeth. Choose safe, light options. Remember, these restrictions are only for the first 48 hours. So, it’s a small sacrifice for a long-lasting bright smile. By taking these simple steps, you can enjoy your new, dazzling smile for a longer time.
