When Can you Eat and Drink After Teeth Whitening?

Posted on: April 16, 2018

If looking in the mirror brings a gasp at the loss of gloss in the enamel of one’s teeth, then teeth whitening is the treatment option for you. No matter how diligent you are with your oral hygiene, it is only a matter of time before your teeth eventually show the signs of discoloration.

What You Need to Do After Teeth Whitening

General causes for a lack of luster in the teeth enamel include aging, the daily ‘grind’ of drinking coffee/tea, fruit juices, red wine, cola drinks, even eating certain fruits and smoking. The stain from tar and nicotine are well known for adding that yellow or brownish stain.

Teeth Whitening Choices

There are a few choices to bring back the shine of that smile once lit up any room you entered but in this article, we will be writing about the popular cosmetic procedure known as teeth whitening. Please be aware that a professional teeth whitening process uses a peroxide gel and sometimes a laser light. The light will help speed up the chemicals in the whitening process and should never be in use on teeth that have fillings, decayed teeth or on teeth with intrinsic (internal) issues.

These internal issues bring about discoloring of a tooth or teeth such as when the nerve dies or trauma comes to the tooth. Teeth whitening cannot be done on dental veneers, crowns, or dental bonds nor can this procedure be done for females who are pregnant or nursing. Children under the age of 18 should not have such a procedure performed to their young teeth.  The process of teeth whitening can leave teeth more sensitive, especially if there are exposed roots to teeth due to gum recession.

It is also important to note that a whiter smile does not last forever.  Depending on eating habits, that clean and dazzling white smile could last a minimum six months or a maximum of two years before requiring the whitening process again.

Teeth Whitening Follow-Up Care

One question that people ask is what foods can they eat after a teeth whitening procedure? While your cosmetic dentist gets the final say on that issue, the normal eating and drinking routine can resume 48 to 72 hours after treatment. Teeth are a porous material and the intensity of whitening can bring about tiny ‘holes’ to the teeth enamel that need time to close up.


Eating foods containing any form of color before the ‘holes’ heal will only serve to bring the same discoloration.  In this 48 to 72-hour time frame, people need to follow a white diet. White diet foods include bananas, egg whites, plain white rice without seasoning or spices that can discolor the teeth. The diet can also include white meats of chicken, turkey, pork or white fish without seasoning or breadcrumbs.


Eat pasta without, obviously, red tomato sauce.  Consume clear drinks such as water, white wine, or lemonade, No coffee, tea or colas with caramel coloring. If you have any questions about these steps or teeth whitening in general, give us a call today.
