What Foods Can You Eat After A Teeth Whitening Procedure?

Categories: Cosmetic Dentistry

Teeth whitening procedures are common among coffee and wine lovers who wish to maintain a sparkling white smile. There are plenty of options available when it comes to teeth whitening, including in-office procedures, whitening gels, trays, pens, and LED teeth whitening kits. Regardless of your preferred option, the choice of foods after the procedure is vital to maintaining your white teeth. Dentists advise that adopting a white diet after teeth whitening helps avoid staining your newly whitened teeth. 

A common rule of thumb is that anything that can stain your white teeth can stain your whitened teeth. Teeth are most susceptible to staining after a whitening procedure, especially during the first 48 hours after the procedure. It is, therefore, important to understand the right foods to turn to after the procedure.

What are The Immediate Effects of Teeth Whitening?

The tooth consists of the root, neck, and crown. Whitening affects the crown alone, which is the part of the tooth that you can see. The crown consists of two layers: the enamel and dentin, with the enamel being the outermost layer of the tooth. The enamel gives the tooth its color, which may range from slightly yellow to white.

 Therefore, a whitening procedure only affects the enamel, as it involves removing the stains and plaque on this layer. Dentists advise that you choose carefully what to eat after teeth whitening treatment due to the immediate effects of the procedure. One of the effects is the temporal exposure of the dentine layer. This makes the teeth susceptible to staining by foods.

What Stains Your Teeth?

While this might sound rhetorical, it is important to understand the factors that result in teeth staining so you can carefully choose what to eat after whitening teeth. The three main elements that contribute to the staining of teeth are tannins, chromogens, and acids. These are present in many foods and cause staining by making the enamel weaker, allowing stains to set in easily.

Going without some foods for long may be difficult, but avoiding them for about 48 hours after treatment would help keep your teeth whiter for longer.

What Can I Eat After Teeth Whitening?

 After the procedure, you should come up with a white foods list. This includes all the foods that are least acidic and less likely to cause staining. Here is a list of the recommended foods to eat after teeth whitening:

  • Fish – Go for the white species like albacore and avoid dark fish.
  • Chicken or Turkey – Besides being acid-free, these are healthy and great white foods to eat after teeth whitening.
  • White rice – It is an excellent accompaniment for vegetables and meats.
  • Pasta and white sauce – Avoid colored sauces like green pesto and tomato sauce for a pasta dish.
  • Mashed potatoes – Be sure to peel off the skin before cooking.
  • Bananas – A great snack and are less likely to cause staining to your teeth.
  • Egg whites – remember to remove the yolk before cooking since it is colored.
  • White onion – use this for your cooking and avoid the red onions.
  • Yogurt – eating white yogurt for breakfast helps reduce the risk of staining.
  • White bread – this is a great choice, especially for breakfast.

Other foods that are good for eating after teeth whitening include flour tortillas, porridge, white cheese, apples, cauliflower, and celery.

What Foods Should I Avoid After Teeth Whitening?

 You probably already have an idea of the foods to avoid after teeth whitening, now that you know what’s recommended. Read on to find out the greatest offenders.

  • Coffee: Some people might find it difficult to leave this one out entirely. As such, it is advisable to add milk and limit the amount taken in a day.

Teeth Whitening Aftercare Tips

Besides choosing your diet carefully after a whitening procedure, it is essential to keep some aftercare tips in mind. Here are some tips that will help reduce the effects of teeth whitening and keep your teeth whiter for longer.

Temperature Tenacity

After teeth whitening, teeth are not only susceptible to staining but sensitivity as well. As such, all the foods that are recommended for eating after teeth whitening should be at room temperature. This is because, after the procedure, your teeth are highly sensitive to hot or cold foods, which causes pain and probable damage to your teeth.

Other aftercare tips include: 

  • Brushing your teeth at least twice every day.
  • Flossing at least once a day to avoid plaque buildup over time.
  • Rinsing your mouth with an antibacterial mouthwash at least once a day. This also helps prevent plaque buildup by eliminating bacteria.
  • If possible, use whitening toothpaste at least twice a week. This acts as a basic touch-up and helps remove any stains on your teeth, which goes a long way towards preventing discoloration.
  • Consider touch-up sessions. Depending on your lifestyle and diet long after a whitening procedure, it is important to schedule a touch-up session with your dentist bi-annually.
  • Visit your dentist regularly to have your teeth checked.


Whitening is essential in restoring your white teeth. And while the procedure may be necessary, the question of what foods to eat after teeth whitening is crucial to avoid staining after the procedure. Dentists generally advise that you avoid acidic and colored foods after teeth whitening.
