Top 7 Foods That Stain Your Teeth — And What to Eat Instead

‍

If your smile looks a little dull lately, your diet might be the reason. Some foods and drinks are notorious for staining teeth — even if you brush regularly.

At Huntington Family Dental, we help Calgarians brighten their smiles every day through professional teeth whitening, but what you eat plays a big part in keeping your results long-lasting.

Understanding which foods cause stains and which ones can help keep your teeth white is the first step toward maintaining a radiant smile. This guide will walk you through the top culprits for tooth discoloration and offer some delicious, smile-friendly alternatives.

How Do Foods and Drinks Stain Teeth?

Before we list the culprits, it's helpful to understand how staining happens. Your teeth are made of a hard outer layer called enamel, which is covered in microscopic pores. When you consume certain foods and drinks, three main factors contribute to staining:

1. Chromogens: These are intensely pigmented molecules that can stick to and penetrate the enamel.
2. Tannins: These plant-based compounds make it easier for chromogens to attach to your teeth.
3. Acids: Acidic foods and drinks can soften and erode your enamel, making it rougher and more susceptible to stains.

Now, let's look at the seven most common offenders that can stain your teeth.

7 Foods and Drinks That Stain Your Teeth

You might be surprised to find some of your daily staples on this list. While you don't have to eliminate them completely, being mindful of their effects can help you protect your smile.

1. Coffee and Tea

Your morning cup of coffee or tea is a major contributor to tooth discoloration. Both beverages are rich in tannins, which cause staining compounds to latch onto your teeth. Black tea, in particular, can be even more staining than coffee.

What to eat instead: If you can't give up your caffeine fix, consider switching to green or white tea, which are lower in tannins. Rinsing your mouth with water after your morning brew can also help minimize staining.

2. Red Wine

That relaxing glass of red wine with dinner contains both dark chromogens and tannins. The combination makes it one of the most well-known causes of tooth stains. The acidity in wine also temporarily softens enamel, allowing the colour to set in.

What to drink instead: White wine is less likely to stain, but be mindful that its acidity can still make your teeth more vulnerable to stains from other foods. As with coffee, a quick rinse with water after enjoying a glass can make a big difference.

3. Berries and Dark Fruits

While packed with antioxidants, deeply coloured fruits like blueberries, blackberries, pomegranates, and cherries are also full of staining pigments. If a fruit can stain your clothes, it can probably stain your teeth too.

What to eat instead: You don't need to avoid these healthy fruits altogether. Just be sure to rinse your mouth with water after eating them. You can also mix them into yogurt or a smoothie to reduce their direct contact with your teeth. Lighter-coloured fruits like apples, pears, and bananas are excellent smile-friendly options.

4. Dark Sauces

Rich sauces like soy sauce, balsamic vinegar, and tomato sauce are highly pigmented and often acidic. Think about how easily a drop of soy sauce stains a white shirt—it has a similar effect on your teeth over time.

What to eat instead: Opt for lighter-coloured sauces like a creamy Alfredo or a lemon-butter sauce. When you do have darker sauces, try not to let them linger in your mouth for too long and follow up with a glass of water.

5. Beets

Beets are known for their vibrant, deep red colour that can stain anything they touch, including your teeth. Whether you enjoy them juiced, roasted, or in a salad, their powerful pigments can leave a mark.

What to eat instead: Lighter-coloured root vegetables like cauliflower, parsnips, and potatoes offer great nutritional value without the staining risk. If you do eat beets, brush your teeth about 30-60 minutes afterward to remove the colourful residue.

6. Curries

The rich, yellow pigment in curry powder can lead to significant yellowing of your teeth over time. Turmeric, the main spice in many curry dishes, is a potent staining agent.

What to eat instead: While it's hard to replicate the unique flavour of curry, you can explore other flavourful, less-pigmented spice blends. When you indulge in a curry dish, pair it with crunchy, teeth-cleaning foods like raw carrots or celery.

7. Sodas and Sports Drinks

Dark-coloured sodas like cola are not only acidic but also contain staining chromogens. Even light-coloured sodas and sports drinks are highly acidic, which erodes enamel and primes your teeth for stains from other foods you consume.

What to drink instead: Water is always the best choice for your oral and overall health. If you crave something with a bit of flavour, try sparkling water with a slice of lemon or cucumber.

Foods That Help Keep Your Teeth White

Protecting your smile isn't just about avoiding certain foods; it's also about incorporating foods that naturally clean your teeth.

• Crunchy Fruits and Vegetables: Apples, celery, and carrots act like natural toothbrushes, scrubbing away plaque and surface stains as you chew.
• Dairy Products: Cheese, milk, and yogurt are rich in calcium and phosphates, which help strengthen tooth enamel. The lactic acid in these products may also help prevent decay.
• Strawberries: Surprisingly, strawberries contain malic acid, a natural astringent that can help remove surface stains.
• Leafy Greens: Spinach and kale are packed with minerals that can help build a protective film over your enamel, reducing the chance of stains.
