What Happens After Teeth Whitening?

A chemical reaction happens immediately after a professional teeth whitening treatment. Standard tooth whitening procedures may cause such responses to the teeth.

The most common components are hydrogen peroxide and carbamide peroxide. They undergo a process called oxidation, where the oxygen atoms lose electrons and change the makeup of the teeth.

This process alters the chemical makeup of stains, lightening the color of dental enamel. Chemical activities cause temporary damage to your teeth and gums. They expose the dentin layer underneath the enamel, making it susceptible to erosion and bacterial growth.

The tooth enamel becomes porous, absorbing color more readily. In addition, the gums become sensitive and inflamed after coming into contact with these chemicals. 

Although these are just transitory side effects, it is critical to follow post-treatment recommendations. Make wise meal choices, particularly in the following 48 hours when your teeth are most vulnerable.

Which Foods Easily Stain Your Teeth?

To answer the question, "What to eat after teeth whitening?" You must first understand the dietary elements that discolor your teeth.


Chromogens are chemical compounds that are added to food coloring to create a colored final product. When these colored particles attach to the tooth enamel, they produce significant discoloration.


Tannins are naturally occurring chemicals present in grape skins, seeds, and stems. They are bitter and contribute to staining by increasing the capacity of chromogens to attach to tooth enamel.


Acid weakens the enamel, causing rough spots and erosion on the smooth surface. Teeth get readily stained when exposed to acid.

Stain-Causing Beverages

These are some stain-causing food ingredients that you can find in popular beverages. 

  • Coffee - Coffee is acidic and contains a lot of chromogens.
  • Black/ Green Tea - Black/green tea has more tannins than coffee and stains more than coffee.
  • Red Wine - Red wine is acidic and high in tannins and chromogens.

Try to avoid these beverages in the first 48 hours after teeth whitening. It will help keep your teeth whiter for a more extended period. Afterward, you should use a straw to prevent the liquid from getting all over your teeth. 

The easiest way to avoid stains is to rinse your mouth with water and brush your teeth immediately after eating or drinking.

Best Foods to Eat After Teeth Whitening 

So, what can you eat after you've had your teeth whitened? 

You should probably introduce the white diet. The fundamental of the white diet is to commit to consuming exclusively light-colored or white foods and beverages. This should be done within 48 hours after a teeth whitening treatment.

Here is a list of white diet-recommended meals and beverages:

  1. Apple

The apple is often known as "nature's toothbrush." Biting off the thick skin and fibrous meat of an apple cleans your teeth of plaque and buildup. Apples are likewise high in vitamins and minerals but bear in mind that they are acidic and high in sugar.

To neutralize the acids, eat apples with other meals or all at once to reduce the time acid and sugar remain on your teeth. To avoid damaging your teeth' enamel, always use water to rinse your mouth and wait 30 minutes before brushing your teeth.

  1. Banana

Bananas are high in magnesium and Vitamin C. Magnesium promotes bone growth and the development of good enamel. Vitamin C aids in the maintenance of healthy gums by mimicking the blood vessels that support your teeth. Bananas are also less acidic than other fruits. 

  1. Cauliflower

This superfood requires a significant amount of chewing. It eliminates plaque and buildup on teeth since it is broken down into small pieces. Cauliflower also includes potassium, magnesium, vitamin K, and zinc, all of which are beneficial to the health of your teeth.

  1. Celery

Celery is often referred to as "nature's floss." Aside from scraping food particles from teeth, its crunchiness also increases saliva. This stimulation loosens and flushes away the germs.

  1. Nuts & Seeds

Nuts and seeds contain phosphorus, which aids in calcium absorption by the teeth. Their abrasiveness also aids in the removal of surface stains.

  1. Egg Whites

Egg whites contain 90% water and 10% protein. To prevent tooth stains, fat, and cholesterol, remove the yellow yolk.

  1. Dairy Products

Dairy products, which include casein, are rich in calcium. Casein is a protein family that aids in cavity healing by binding calcium phosphates. It also keeps germs that cause cavities from adhering to the tooth's surface. Therefore, dairy products are generally beneficial to dental health.

The following dairy products are the best for your freshly whitened teeth.

  • White cheese: Some dairy products like Fate, Ricotta, and Gruyere contain calcium and phosphate, which naturally straighten teeth. It also raises the pH levels in the mouth due to chewing. This causes more saliva to be produced, protecting teeth from acids that cause decay. Cheese components adhere to the enamel, protecting it from acids.
  • White Unsweetened Yogurt: Sweetened and creamy yogurts have less protein and therefore less calcium. As a result, opt for the unsweetened version instead.
  • Skimmed Milk: They help you get the nutrition you need without the fat and calories.
  • Lean Proteins:Foods like fish, chicken, and tofu are high in phosphorus and protein, which help to maintain healthy teeth. To prevent tooth discoloration, eat only white fish and skinless chicken or turkey. Tofu made from soybeans is similarly high in calcium, with one 3.5 oz piece containing about 176 mg.
  • Carbohydrates:Because carbohydrates are one of the leading causes of dental decay, choosing carbs is essential to balance your diet carefully. White bread, white rice, white potatoes, and white sauce pasta are all acceptable in moderation on the white diet.
  • Beverages: If you aren't happy with tap or bottled water, you may drink still, unflavored, sparkling water. Coconut water is also a great option since it is high in Vitamin C.

milk, yogurt and white cheese

Although alcohol consumption is not advised owing to its acidity, modest quantities may be consumed. Good examples are white wine or clear liquor with clear mixers, such as gin & tonic and vodka.
