Keep reading to learn more about the causes and solutions for Unbearable pain after Teeth Whitening.

Causes Of Unbearable Pain After Teeth Whitening 

Most Teeth whitening treatments, whether done at home or professionally, use bleaching agents to remove stains from the enamel. Although the bleaching agents are safe, they can still cause increased sensitivity and discomfort due to various reasons.

Heightened Tooth Sensitivity

One primary reason for post-whitening tooth pain is the escalation of tooth sensitivity.

When peroxide-based whitening agents penetrate the enamel to break down stains, they create tiny pores in the teeth. This exposes nerve endings and results in heightened sensitivity to hot or cold stimuli. It causes:

  • Pain or discomfort while biting or chewing
  • Sensitivity during brushing or flossing.
  • Higher chance of getting tooth decay or cavities.
  • Risk of gum recession and periodontal problems.

Gum Irritation and Sensitivity 

The improper application of whitening agents can lead to swollen, sensitive, and even bleeding gums, which contributes to discomfort after the procedure. Therefore, it’s important to follow the instructions provided with at-home kits or seek assistance from a qualified dental professional proficient in the application of these products.

Excessive use of whitening products can cause discomfort 

Sometimes, people want their teeth to get whiter quickly, so they use whitening products more often than they should. But doing this can make their teeth very sensitive and cause a lot of pain.

Tips to Get Rid of Unbearable Pain after Teeth Whitening 

Here are some practical solutions to ease unbearable pain after tooth whitening:

Select the Appropriate Whitening Product 

Consult a dentist to find the best whitening product for your needs. If you’re using an at-home solution, seek guidance from your dentist to choose the most suitable option based on your oral health and sensitivity.

Use Desensitizing Toothpaste 

If your teeth feel more sensitive after Whitening, use a desensitizing toothpaste. With regular use, it builds a protective layer on your teeth and reduces sensitivity over time.

Use Fluoride Mouthwash 

Include fluoride mouthwash in your routine. It strengthens tooth enamel, decreases sensitivity, and boosts overall oral health. Many people find it helpful, especially after whitening treatments.

At-home remedies for unbearable pain after teeth whitening

Here are some at-home remedies to ease discomfort after tooth whitening:

Apply Cold Compresses 

Applying a cold compress to the affected areas offers quick relief from pain and discomfort. 

Use Pain Relievers 

Over-the-counter pain relievers like ibuprofen or acetaminophen can help ease pain and discomfort. Make sure to follow the recommended dosage and consult a healthcare professional if the pain continues.

Try a Warm Saltwater Rinse 

Rinsing with warm salt water can ease irritated gums and support healing. Gargle with a saltwater solution several times a day to get relief and aid in the recovery process.

Avoid Trigger Foods and Beverages 

Some foods and drinks, particularly those with extreme temperatures or high acidity, can worsen tooth sensitivity. It is better to avoid these triggers during the recovery to minimize additional discomfort.
