Foods to Avoid

Showing off your pearly whites is a great way to show the health of your teeth. But if you’re constantly eating foods that can discolor your teeth, maintaining a white smile can be challenging. Learn more about different foods you should avoid or monitor to keep your smile bright.

Acidic Foods

The yellow tinge on your teeth could be caused by acidic foods, like citrus food or tomatoes. These foods aren’t bad for your health, but the acid in these foods can erode your enamel and turn your teeth more yellow.

Pigmented Berries

Berries like blackberries, blueberries, or pomegranates are richly pigmented. This means that the pigmentation can stain your teeth after you eat them. Try brushing your teeth to clean them or avoid eating pigmented berries when you want whiter teeth.


Many people love their cup of coffee or tea in the morning. But they both contain something called tannins that can stain and discolor your teeth. If you drink coffee or tea every day, it can be hard to maintain or get white teeth.

If you can’t give up your cup of caffeine, there are different ways you can keep your teeth safe. Instead of sipping on coffee or tea throughout the day, and constantly exposing your teeth, drink it all in one sitting. Then make sure you brush your teeth once you’re done to remove any remaining coffee or tea from your teeth.

Candies and Sweets

From time to time, we all have a sweet tooth. But when you eat candies, the leftover bacteria in your mouth becomes a meal for bacteria. When bacteria feeds on that sugar, they release acids that stain your teeth and can cause other problems, like tooth decay.


There are lots of reasons to avoid soda for the health of your teeth and body. But if you’re a big soda drinker and you want whiter teeth, then you should avoid soda. This is because, like with the candies, the sugar in soda is eaten by the bacteria in your mouth, causing stains and discoloration.

If you can’t stop drinking soda, think about how you consume it. Like with the coffee and tea, don’t sip on soda throughout the day, otherwise you’re constantly feeding that bacteria in your mouth. Instead, enjoy your soda in one sitting and brush your teeth afterwards to remove any extra sugar.

Teeth Whitening at Your Local Dentist

If any of these foods are a common part of diet, make sure you pay attention when you eat these foods. While you don’t have to avoid eating cirtusy foods or drinking coffee, consider brushing your teeth after those foods to avoid discoloration.

And, while you can avoid different foods to help keep your teeth white, teeth whitening can help give your teeth the boost they need. Just see if your local dentist can help whiten your teeth! At Fort Collins Dental Arts, we offer teeth whitening services to help you find your white smile again.
