What Can’t I Eat After Teeth Whitening?

As discussed earlier, tooth whitening is a process aimed at removing stains from the surface of the teeth. When you whiten your teeth, you remove tiny particles (which are normally considered harmless) from your teeth and this may expose sensitive material inside the teeth.

So as a precaution against this, you must avoid certain foods for a while after teeth whitening.


If you are someone who regularly eats french fries, onion rings, chips or any other fried food, you should temporarily stop eating if you want to whiten your teeth.

The first time you consume the fried food, it may be fine but chips, french fries and fried onion rings have a really high sugar content.

Over time, these things will decay your teeth and make them darker again. So be smart, and look for more healthy alternatives.

Also, it is important to know that just dipping your fries in ketchup doesn’t actually save your teeth from the damaging effects of the fatty oil!


Like french fries, sugar and carbonated drinks are harmful to your teeth.

Sugar binds to existing plaque on your teeth and forms a mineralized odontogenic cyst (Tartar), which is called dental calculus or tartar.

Avoid Darkly-Colored Foods

Despite your teeth looking brighter and whiter than ever, red wine, tea, coffee and juices containing dark pigments may stain them in no time. Chewing tobacco is another common offender, influencing teeth to darken over a short period.

The reasons behind teeth becoming darkened by foods and drinks is the staining agents that linger on the teeth after teeth whitening treatment. These pigments are transferred into the teeth, leading to discoloration.

Staining from teeth whitening treatment typically takes place within the first 24 hours. However, it may appear gradually over a few days. You should avoid chewing tobacco after teeth whitening.

To Get the Best Results, Customers Should Avoid Red Foods That Stain Teeth Immediately After Teeth Whitening.

Many customers may be satisfied with their teeth when they leave a dentist. They feel proud of their new and whiter teeth. However, they do not care that they cannot touch certain foods or beverages after teeth whitening treatment.

It is important to avoid the foods that stain teeth immediately after teeth whitening. Thus, you can keep your teeth white for a longer period of time.

If you choose to have a teeth whitening treatment, it is important to read about the side effects. Ask your dentist for some advice before the procedure. You can also purchase a whitening toothpaste and dental products after teeth whitening.

Cut Out Acidic Foods

Sharp white teeth are attractive to the eye, but they are also the result of a build-up of hard enamel. Enamel protects teeth from the harsh outside world and keeps them protected and strong.

During teeth whitening, enamel gets worn away, so keeping it in its best shape is key to keeping your new bright smiles. Teeth whitening removes the outer teeth coating or hard enamel and to re-form it back to its original shape, you need to stay away from acidic foods.

Acidic foods disrupt the process of diffusion, which takes place inside teeth. When teeth absorb acidic foods, the tooth’s surface reacts with the acidic food, which changes the chemistry of the tooth’s surface and slows down the diffusion rate.

The process of diffusion in enamel is normally a long, gradual process, which may actually take several years.

So fast foods, soft drinks, and meal times should be kept away from as much as possible in order to ensure that your enamel is protected and your teeth stay strong and fully formed.

What Can I Eat After Teeth Whitening?

If you’re like most people, you’re probably so excited about your teeth whitening results that you want to go out and buy everything that you can get your hands on! Even so, it’s best to avoid certain types of foods until your teeth have had a chance to adjust.

So, what foods should you avoid after you whiten your teeth? What does your dentist recommend? Here’s a quick summary:

Avoid eating hard, crunchy food items for at least the first 24 hours after your teeth whitening session. This is particularly important if you have sensitive teeth.

Avoid any foods that are icy cold or hot for at least 2-3 hours after your session.

Hot or spicy foods should be off-limits until your mouth has had a chance to adjust.

Drinking citrus juices, sports drinks, or alcohol can stain your freshly whitened teeth for up to twenty-four hours after treatment.

Even with all the restrictions, you can still eat anything that’s not a crunchy, icy cold, hot, spicy, or acidic food item.
