Whitening MythBusters

One of the most common questions about teeth whitening is whether there are foods and drinks that should be avoided. There are several foods and beverages that can stain or darken teeth during or after a whitening treatment. Consuming these items will affect everyone differently due to genetics and frequency of consumption, but we're happy to offer some guidelines so you can maximize the results of your Opalescence whitening treatment!




This morning staple is the biggest deterrent to maintaining a white smile. If you're not willing to give it up, make sure to keep a few extra Opalescence Go Trays or Opalescence PF Syringes in the refrigerator so you can touch up your smile within a few months of your last whitening session.

Many people don't realize that this delicious staple of Italian cuisine can stain their teeth due to its rich red color and acid content. If you've just whitened your teeth and want to avoid staining, make sure to consume it in moderation.



Blame the acidity in red wine—and, yes, white wine, too—for this beverage's effect on tooth coloration. Avoid consuming wine during a whitening regimen or make sure to brush as soon as possible after having a glass. And again, it might be wise to keep a few spare whitening trays or syringes around for touch-ups if you're a frequent wine drinker.



If you've ever gotten blueberry juice on a crisp white shirt or light-colored carpet, you're familiar with the staining power of this nutritious dark purple berry. Also, foods high in citric acid, like blueberries, can cause sensitivity while whitening. However, there's no need to give up the benefits of blueberries for good. Just make sure to brush immediately after eating these antioxidant-rich fruits.



Aside from the sugar content in soda, which triggers tooth decay, dark-colored sodas can contribute to tooth staining. If you can't resist them, try sipping them through a straw to minimize contact with teeth.



Just like blueberries, beets are both nutrient-dense and vibrant in color—color that has a lot of staying (and staining) power. Make sure to brush after consuming beets. If they're a mainstay in your diet, you may consider more frequent whitening touch-ups.



Tea is a daily—sometimes multiple-times-a-day—ritual for many people around the world. The color and tanic acid found in black tea can contribute to the yellowing and browning of teeth, so make sure to brush often and keep spare whitening touch-up kits in the refrigerator to keep your smile sparkling.



Although it doesn't fit into the category of a food or drink, smoking or chewing tobacco also contributes to teeth discoloration. Avoid tobacco or plan on more frequent whitening touch-ups to maintain a bright smile.

The best thing you can do to keep your smile bright white is to brush your teeth after eating and drinking, specifically after consuming dark foods and liquids. Coffee, tobacco, and other dark foods and liquids can restain the teeth over time. Should this occur, the teeth can be re-whitened within a few nights with Opalescence whitening touch-ups. Also, regular dental checkups and cleanings are important before and after whitening to maintain a healthy smile.​
