If you had your teeth professionally whitened, then you may want to keep your smile bright for as long as possible. Brushing and flossing consistently are great things to do, but changing your diet can be effective as well. Certain foods you eat can increase your risk of stains. To help you get the most out of your investment, you should avoid these four items.

Acidic Options

Acidic foods don’t discolor teeth themselves, but rather they increase your risk of this flaw. Oranges, grapefruits, tomatoes, limes, and the like wear down your enamel the longer they sit on it. A weakened outer layer can allow dark particles to penetrate deeper while also causing sensitivity. Thankfully, you can neutralize any acids in your mouth with water.

Dark Beverages

Coffee, tea, and red wine are classic drinks people love, but they have chromogens and tannins. These chemicals are responsible for the color and bitter taste you like, but they lead to stains. The more you have them, the more the pigments can cause problems. If you do indulge, then rinse with water to wash away lingering particles in your mouth.

Some Fruits & Vegetables

Fruits and vegetables are an essential part of a healthy diet, but a few dark-colored options can be trouble. Berries, cherries, beets, and pomegranates are a few fan favorites you should be wary of. Reach for safer options, like bananas, pears, strawberries, broccoli, and celery.

Dyed Foods

This point might seem obvious, but a refresher can be a good reminder. Sports drinks, popsicles, and candy can discolor your teeth if you aren’t careful. Although cutting them out of your diet might be tough, keeping them in moderation can be helpful.

A good rule of thumb you can follow is: if it can stain a shirt, then it can do the same for your grin. By being more conscious about what you eat, you can keep your results bright for longer. That way, you feel better about showing off your renewed look and protect the investment you made.
