Top Teeth-Staining Foods and Beverages
Certain foods and drinks are famous for staining freshly whitened teeth. However, the need for a “white diet” after teeth whitening has been a bit of a debate.
Some studies suggest avoiding foods like coffee, red wine, and berries can help keep your smile bright longer (this study found no significant differences between coffee and the control group, but red wine, cola, and tea caused more staining at all tested times). Some other studies show that these dietary restrictions don’t really affect the overall whitening results (see study here).
“The key takeaway is that while the white diet isn’t absolutely necessary to maintain your results, it can definitely help prevent staining right after the treatment. This is especially true during the first 48 hours when your teeth are more porous and likely to absorb color.” – Dr. Zolfagharirad, Smile Avenue Dentistry
1. Dark Berries and Fruits
While fruits are generally great for your health, dark-colored berries like blueberries, blackberries, and cherries are not a good diet choice if you want to avoid staining. Their vibrant pigments can cling to your enamel and leave unwanted stains. Even juices made from these fruits are best avoided.
Pro Tip: Choose lighter fruits like bananas, apples (without the skin), or pears. They’re less likely to stain and are still packed with nutrients.

2. Coffee, Tea, and Soda
As much as you love your morning coffee or afternoon tea, these drinks are notorious for staining teeth. Dark sodas can also cause discoloration due to their color and acidity. Additionally, the acids in these beverages can weaken enamel, making your teeth more susceptible to staining.
Pro Tip: If you can’t give up your caffeine fix, consider drinking through a straw to minimize contact with your teeth. Also, try rinsing your mouth with water afterward.
3. Red Sauces and Curry
Rich, flavorful dishes like spaghetti with marinara sauce, Indian curries, and even some tomato-based soups can cause staining. Their intense colors and high acidity are a double threat to your freshly whitened teeth.
Pro Tip: Choose lighter alternatives like Alfredo sauce or creamy dishes during the first few days after your whitening treatment.
4. Acidic Foods and Beverages
Citrus fruits, vinegar-based dressings, and even some pickled foods can weaken enamel and make your teeth more prone to staining. Acidic foods also increase sensitivity, which can be uncomfortable after a whitening procedure.
Pro Tip: Stick to non-acidic options like cucumbers, lettuce, and lean proteins. If you consume something acidic, rinse your mouth with water afterward to neutralize the acid.

5. Staining Snacks (e.g., chips, colored sweets)
Brightly colored candies, chips with artificial dyes, and even dark chocolate can transfer their colors to your teeth. These snacks not only risk staining but are also not great for your overall oral health.
Pro Tip: Go for plain, tooth-friendly snacks like rice cakes, plain popcorn, or unsweetened yogurt.
In addition to avoiding stain-causing foods and drinks, it’s important to avoid using tobacco products. Smoking and chewing tobacco can cause stubborn tooth stains, yellowing enamel, and bad breath.

2. Hydrating Properly to Protect Teeth
Drinking plenty of water is essential for maintaining oral health and keeping your teeth white. Water helps wash away food particles and neutralizes acids in your mouth.
Pro Tip: Try sipping on plain water throughout the day. If you need a flavored option, consider infusing your water with light-colored fruits like cucumber or mint.
