What Not to Eat After Teeth Whitening? Complete Information

Teeth whitening is a popular procedure that can brighten your smile and boost your confidence. However, post-whitening care is crucial to maintain those dazzling results. Whitening makes teeth more porous and sensitive. So, they are more susceptible to staining. To keep your smile bright, it’s essential to avoid certain foods and beverages. This guide will help you understand what not to eat after teeth whitening. It will also offer better options.

Understanding Teeth Whitening

Before listing the foods to avoid. It’s helpful to understand why some can harm your newly whitened teeth. During the whitening process, your enamel is temporarily weakened. This makes your teeth more porous and vulnerable to staining and sensitivity. Avoid some foods for at least 48 hours after treatment. This can protect your enamel and keep your teeth white.

The Three Culprits: Chromogens, Tannins, and Acids

Three main factors contribute to tooth staining: chromogens, tannins, and acids. Chromogens are pigmented compounds that adhere to tooth enamel. Tannins, found in beverages like tea and coffee, enhance chromogen adherence. Acids erode enamel, making teeth more susceptible to stains. Avoiding foods and drinks containing these culprits is crucial after whitening.

How Much Does Teeth Whitening Cost?

Foods and Beverages to Avoid

1. Dark-Coloured Beverages

Coffee and Tea: Both beverages contain tannins that can stain your teeth. If you must drink them, use a straw and rinse your mouth with water immediately afterward.

Red and White Wine: Red wine has dark pigments and acids that can stain teeth. White wine, though lighter, is acidic and can weaken enamel.

Soda and Fizzy Drinks: These drinks are high in sugar and acids, which can erode enamel and cause stains. Avoid them for at least 48 hours after whitening.

2. Dark-Coloured Foods

Dark Fruits and Vegetables: Avoid blackberries, blueberries, cherries, grapes, and pomegranates. Also, avoid beets and dark leafy greens like spinach. These foods contain pigments that can stain your teeth.

Tomatoes and Tomato Sauces: Tomatoes are highly acidic and have dark pigments. Avoid tomato-based sauces, ketchup, and similar foods.

Dark Sauces and Condiments: Soy sauce, balsamic vinegar, and other dark sauces can stain teeth. If it can stain a white t-shirt, it can stain your teeth.

3. Acidic Foods and Beverages

Citrus Fruits: Oranges, lemons, limes, and grapefruits are highly acidic and can erode enamel, making your teeth more vulnerable to stains.

Fruit Juices: Avoid dark-coloured and acidic juices like grape juice, cranberry juice, and orange juice. They can weaken enamel and stain teeth.

Pickled Foods: Pickles and other pickled foods are acidic and can affect your enamel. Avoid them after teeth whitening.

How Long Does Teeth Whitening Last?

4. Sugary Treats

Sugary Foods: Sugary foods can cause tooth decay and discoloration. They include cakes, cookies, candy, chocolate, and ice cream. This is especially true when your teeth are sensitive after whitening.

Sweets with Dyes: Avoid sweets with artificial or natural dyes. This includes popsicles and certain candies. They can stain your teeth.

5. Miscellaneous

Processed Meats: Some processed meats are acidic and can stain your teeth. It’s best to avoid them after whitening.

Tobacco: Smoking can cause severe staining and damage to your teeth. Avoid tobacco products entirely for a brighter smile.

Safe Foods to Eat

Instead of dark and acidic foods, opt for lighter, less pigmented options. This “white diet” helps maintain your bright smile.

Chicken and Turkey: These are light-coloured, healthy, and free from staining pigments.

Fish: White fish like cod or haddock is safe to eat. Avoid darker fish varieties.

Rice and Pasta: These are excellent choices, but avoid dark sauces.

White Cheese: This is a great option, but pair it with light-coloured foods.

Egg Whites: Egg whites are safe, but avoid the yolk as it contains colour.

Potatoes: Peeled potatoes and mashed potatoes are good options.

White Bread: Remove the crust to ensure it’s safe for your teeth.

Bananas: These are light-coloured and won’t stain your teeth.

Yoghurt: Opt for plain white yoghurt without added colour.

Porridge: Enjoy porridge with milk, and if you need sweetness, use a sweetener instead of sugar.

Long-term Tips

You must follow the white diet for the first 48 hours. But, to keep your teeth white for the long term, you must keep up good oral hygiene. Brush and floss regularly, and visit your dentist for regular cleanings. Drink plenty of water and consider using a straw for any staining beverages you can’t avoid.


Teeth whitening can give you a beautiful, bright smile. But, you must care for your teeth after to keep the results. Avoid dark-coloured, acidic, and sugary foods and beverages for at least 48 hours. Stick to lighter, less pigmented options to keep your teeth white and healthy. With these tips, you can enjoy your dazzling smile for a long time.
