What Should You Avoid After A Teeth Whitening Session?

Teeth whitening is one of the most popular cosmetic treatments, delivering a brighter smile and boosting self-confidence. 

According to the American Dental Association (ADA) research, teeth whitening is the most popular cosmetic dental treatment. More and more people are trying it, and the trend is powerful among people under 45.

While teeth whitening removes the stains effectively, teeth become sensitive, and whatever you eat and drink after the treatment plays a significant role in your teeth’s health.                               

Your smile deserves the right care- that’s where aftercare of the teeth comes in. 

This guide provides key tips for protecting your newly whitened teeth, including foods to avoid, managing sensitivity, and maintaining long-term results for a healthy smile.

Immediate Aftercare (48 Hours)

Foods And Beverages To Avoid 

Many people usually have a question: “Can I eat after teeth whitening?”

Well, the answer is yes, you can eat, but it’s important to understand what to eat. Some foods and drinks can stain the freshly whitened teeth and can cause irritation or sensitivity issues.

Here is what you should consider:

• Drinks: 

Coffee, tea, red wine, and citrus juices

• Dark-Colored Foods:

Berries, soy sauce, tomato sauces, and beets

• Acidic foods:

Tomatoes, citrus fruits (lemons, oranges, grapefruits), and pickles

• Sugary or sticky foods:

Candy, chocolate, and sticky snacks like caramel

Habits To Avoid

Healthy habits preserve the brightness and overall health of the teeth. However, some habits can reduce the overall result of teeth bleaching; therefore, it’s necessary to avoid some habits to prevent discoloration and sensitivity.

Here is what you should avoid:

• Tobacco:

Smoking or taking tobacco products

• Harsh Brush:

Brushing with a hard toothbrush and abrasive toothpaste.

What Is Teeth Sensitivity After Whitening?

After teeth bleaching, you might feel some sensitivity, but it’s completely normal and happens for a short period. Let’s understand why this happens and how to manage it. 

Why Does Tooth Sensitivity Occur?

• It happens because teeth whitening affects the hard outer layer of the tooth, i.e, enamel.
• During the treatment, the enamel pores open, which causes sensitivity to hot and cold food. 
• Also, the whitening agents can temporarily irritate the nerve inside the teeth. 

Sensitivity in some people lasts from 24 to 48 hours after the bleaching process, whereas some might feel it for a week. 

How To Manage Sensitivity?

• Use toothpaste that eases the sensitivity by blocking the pain signals.
• Hot or cold drinks can trigger the sensitivity, so prefer lukewarm beverages with optimal temperatures.
• Avoid using a hard brush as it can affect the gums and damage your enamel. 
• Use over-the-counter products like gel to reduce sensitivity.

What Are The Best Foods To Eat After Whitening 

For 48 hours after teeth bleaching, it’s important to eat foods and drink beverages that do not cause staining or irritation.

• Rice
