Teeth whitening procedures have been fairly popular. Around 35 million Americans have undergone teeth whitening. Understanding the timing of resuming normal eating habits after teeth whitening is crucial for optimizing the procedure’s results. 

This article will guide you on when to start eating normally after teeth whitening, the type of foods one can have, and what to avoid for the best results.

What is Teeth Whitening?

Teeth whitening is an aesthetic dental procedure for a brighter smile. According to the American Academy of Cosmetic Dentistry (AACD), 71% of Americans have undergone teeth whitening procedures. 

Teeth whitening treatments can be administered in two primary ways: through procedures performed by a dentist or using at-home whitening kits. It uses bleaching agents like peroxides, either hydrogen or carbamide.

These agents remove discoloration from the enamel. Besides whitening, the teeth become more porous. The teeth are susceptible to staining, making the whitening procedure useless. Post-whitening care is thus important.

When Can You Eat Normally?

It is better to avoid pigmented foods and beverages as much as possible. The initial 48-hour period right after teeth whitening is the key period. It is advisable to be cautious to ensure the best results.

What to Eat After Teeth Whitening?

Dentists suggest a “white diet” for at least 24–48 hours after teeth whitening.

A white diet consists of light-colored foods like chicken, tofu, fish, rice, and pasta. These are non-pigmented and acid-free.

Foods included in the white diet are:

Clear Fluids

Water is the recommended drink as part of the white diet during the first 48 hours.

Other clear fluids include sparkling water, skimmed milk, and tonic water.

Why Do Certain Foods Cause Staining?

Food items containing the following compounds cause staining

  1. Chromogens are chemical compounds used as a food color. These compounds can cause extreme discoloration.
  2. Tannins are natural compounds found in leaves and stems. They promote the stickiness of chromogens on tooth enamel.
  3. Acid-containing food softens enamel, creating rough surfaces and absorbing stains. The acid penetrates the tooth enamel, causing sensitivity.

Foods to Avoid after Teeth Whitening

After undergoing teeth whitening treatment, it’s essential to avoid certain foods and beverages that can stain or discolor your teeth, ensuring that you maintain the results of the procedure. Here’s a list of foods and drinks to avoid:


  1. Dark-colored beverages containing Tannins
  1. Acidic Foods
  1. Bright Colored Foods
  1. Sugary Foods

Sugary foods like cakes and cookies cause bacterial contamination, which can cause staining.

How to Maintain Your Whitening Results?

  1. Brush your teeth with a whitening toothpaste immediately after eating. Wait at least 4 hours before brushing after teeth whitening.
  2. After consuming foods or drinks, rinse your mouth with water.
  3. Avoid colored toothpaste or mouthwash. Chlorhexidine-containing mouthwashes can cause staining.
  4. Tobacco products can stain your teeth, so one should avoid smoking.
  5. Use a straw to drink beverages with minimal tooth contact.
  6. Consume staining foods and drinks in moderation.
  7. Teeth whitening touch-ups every 6 months.
