Teeth whitening strips are a convenient way to brighten your smile, but many users experience sensitivity, leaving them wondering, “Why do teeth hurt after whitening strips?”
The discomfort is caused by the active ingredients in the strips, which penetrate the enamel to remove stains but can irritate the sensitive layers of your teeth. Understanding the cause and taking steps to prevent sensitivity can help you achieve a brighter smile without the pain.
Why Whitening Strips Cause Tooth Sensitivity
While active ingredients like hydrogen peroxide or carbamide peroxide in whitening strips effectively penetrate enamel to bleach types of teeth stains, this process can cause temporary discomfort by exposing sensitive parts of your teeth. The consistency and duration of using these strips, often impacted by such sensitivity, directly influence your overall whitening longevity.
How Whitening Strips Work
Teeth have microscopic pores in their enamel. Whitening strips work by opening these pores, allowing the bleaching agents to reach the discolored molecules below the surface. This can also expose the dentin layer, which contains tiny tubules connected to nerve endings. When these tubules are exposed, hot, cold, or even air can cause sharp sensations.
Why Sensitivity Happens
Potent bleaching agents are the primary cause of tooth sensitivity. Hydrogen peroxide, in particular, can irritate the nerves inside the teeth. People with gum recession or exposed roots may feel even more pain, as these areas lack enamel protection.
How to Prevent Tooth Pain After Whitening Strips
Preparing your teeth before using whitening strips and making smart choices during and after treatment are important ways to minimize discomfort.
Before You Whiten
- Use sensitivity toothpaste: A few days before using whitening strips, brush with a toothpaste designed for sensitive teeth. These toothpastes, often containing potassium nitrate, help block nerve signals.
- Take pain relievers: Taking an over-the-counter anti-inflammatory like ibuprofen before applying the strips can reduce inflammation and pain.
- Avoid exposed roots: Avoid placing strips on the exposed areas if you have gum recession. These spots are highly sensitive and more prone to discomfort.
Choose Gentler Whitening Products
Alternative whitening products may be a better choice for people prone to sensitivity. Strips with lower peroxide concentrations or carbamide peroxide can be less irritating. Although they may take longer to show results, they are gentler on teeth.
Products like Opalescence Go are designed to minimize teeth sensitivity. These strips require just 15 minutes of wear, reducing the exposure time to bleaching agents compared to longer treatments.
What to Do If Your Teeth Hurt After Whitening Strips
If you experience sensitivity after using whitening strips, there are four steps you can take to ease the discomfort.
- Continue using sensitivity toothpaste: Brushing with desensitizing toothpaste for a few days after treatment can help soothe irritated nerves.
- Use a desensitizer: Ask your dentist about desensitizing products, such as gels or varnishes, that can be applied directly to your teeth. These create a protective barrier to reduce sensitivity.
- Avoid extreme temperatures: Avoid very hot or freezing foods and beverages. Lukewarm options are less likely to trigger sensitivity.
- Take a break: Follow the manufacturer’s instructions for how often to use whitening strips. Overusing them can worsen sensitivity and damage enamel.
Are Whitening Strips Safe?
When used as directed, whitening strips are generally safe. However, if you have pre-existing conditions like gum recession or cavities, consult your dentist before starting a whitening routine. Improper use of whitening products can lead to enamel erosion and long-term sensitivity.
Final Thoughts
If you’ve ever wondered, “Why do my teeth hurt after whitening strips?” the discomfort comes from bleaching agents temporarily exposing sensitive areas of your teeth. While the sensitivity is usually short-lived, it can be avoided by preparing your teeth with desensitizing toothpaste, choosing gentler products, and taking care during the whitening process. For those with severe sensitivity, professional whitening treatments or alternative methods may be better options. By consulting with your dentist and following these tips, you can achieve a radiant smile without the pain.
