Teeth whitening, what not to eat

October 30th, 2016 by Dr. Farokh Zhand

Teeth whitening is a preference to keep teeth in their natural color and maintain a white smile. The teeth whitening process comes with a few food sacrifices that have to be embraced to provide an environment that white teeth thrives on. Some foods have to be foregone to pave way for the desired white teeth.

Proper oral hygiene is of course indispensable for maintaining a bright smile, but there is one other important bit of advice: Watch what you eat and drink. Certain foods and beverages can discolor teeth. If you want to protect your pearly whites, beware of some common culprits that stain your teeth.

These are the foods not to eat in a bid to keep your teeth white;


Drinks such as coffee contribute to teeth staining which consequently leaves the teeth with a color far from white.

Pigments from dark-colored drinks such as coffee, tea, and soda can become embedded in those cracks and ridges and, if the proper steps are not taken, can cause permanent, yellowing stains on your teeth

While it may seem that lighter-colored coffee would stain less, the same pigments and acids are present in coffee with cream as black coffee; thus, adding any sort of whitener to your coffee will not prevent your teeth from becoming stained, unless you put significantly less coffee in your cup to make room for the cream. Giving up coffee, tea, sodas, sports drinks wine or other tooth-staining beverages is the best way to prevent the staining caused by those drinks.

Dark chocolate

In addition to tasting delicious, studies have found that dark chocolate is a potent antioxidant with a variety of health benefits, including lowering blood pressure and helping stave off heart disease. That said, it can still ruin a newly whitened smile. If at all you have an insatiable craving for chocolate, it is recommended that you go for the white chocolate.

Dark colored sauces and berries

Avoid food like dark chocolate, blueberries and beets, and dishes with dark-colored soups or those dipped or marinated in dark-colored sauces. Go on a white diet instead. Fruits and vegetables may be healthy, but many of them can contribute to tooth discoloration. Avoid vegetables like carrots, spinach, beans and broccoli. The only exception is cauliflower. Some fruits are acceptable if you peel their skin, like apples, cucumbers and pears.

Acidic Foods And Beverages

Two of the most common side effects of tooth whitening are transient tooth sensitivity and gum irritation.  Acidic foods will further irritate the gums and sting like a bee. It also increases the sensitivity, especially to cold. Acids are an irritant, so stay away from them for about 48 hours following in-office bleaching and for a couple of hours following home bleaching. These foods include, Acidic foods (such as citrus fruits) Vinegar most sports drinks and vitamin water.

Although the enamel of your teeth is the hardest substance in the human body, it is not flat and smooth. On the contrary, your tooth enamel contains microscopic pits and ridges that can hold particles of food and drink.
