Will Teeth Whitening Make My Teeth Hurt?
Yes, Teeth whitening can sometimes cause temporary sensitivity or discomfort, but it is typically mild and manageable. We will explore why teeth whitening might cause sensitivity, how you can minimise any discomfort, and whether the benefits outweigh the potential drawbacks. Read on for everything you need to know about teeth whitening and sensitivity.
Why Can Teeth Whitening Make Your Teeth Hurt?
Teeth Whitening treatments work by using bleaching agents, such as hydrogen peroxide or carbamide peroxide, to break down stains on the enamel. While effective, these agents can temporarily affect the tiny tubules in your enamel, leading to heightened sensitivity. This is because the peroxide can irritate the nerves inside your teeth, especially if you already have thin enamel or exposed dentin.
Common Causes of Sensitivity During Teeth Whitening:
- Thin enamel: The protective layer over your teeth may be naturally thinner in some people.
- Exposed dentin: Gums that have receded can expose the sensitive dentin underneath the enamel.
- Strength of whitening agents: Professional treatments often use higher concentrations of bleaching agents, which may increase the likelihood of sensitivity.
- Pre-existing dental issues: Cavities, cracks, or gum disease can exacerbate discomfort during whitening.
How Long Does Teeth Whitening Sensitivity Last?
For most people, any discomfort caused by teeth whitening is temporary and should subside within 24 to 48 hours after treatment. In rare cases, sensitivity may persist slightly longer but is typically manageable with the right care. The Oral Health Foundation’s advice on teeth whitening researches further into how long sensitivity lasts; see their page for further information.
How to Prevent or Minimise Teeth Whitening Sensitivity?
To enjoy the benefits of teeth whitening without significant discomfort, consider these tips. Choosing the right whitening method is crucial; lower-concentration whitening products can be less irritating for sensitive teeth. Using desensitising toothpaste that contains potassium nitrate or fluoride can also help block nerve signals and reduce sensitivity.
It’s essential to follow professional guidance if you’re opting for professional whitening, as your dentist can recommend personalised strategies to minimise discomfort. Additionally, limit acidic foods and drinks such as citrus fruits and soda during and after whitening, as they can exacerbate sensitivity. Finally, take breaks between treatments to allow your teeth time to recover, especially if you’re using at-home whitening kits.
Post-treatment care is also important. Avoid extremely hot or cold foods and drinks for at least 48 hours to prevent irritation. Rinsing with lukewarm water or a fluoride mouthwash can soothe your teeth, and using a soft-bristled toothbrush will help avoid further discomfort.
Key Steps to Reduce Sensitivity Post-Treatment
- Avoid extremely hot or cold foods and drinks for 48 hours.
- Rinse with lukewarm water or a fluoride mouthwash.
- Use a soft-bristled toothbrush to avoid irritating your teeth further.
Are Some Whitening Methods Less Painful Than Others?
If you’re worried about discomfort, it’s essential to choose a whitening method that suits your needs and tolerance. Here’s a quick comparison of common whitening methods:
Professional Whitening
High-concentration agents are used under dentist supervision.
Faster results but may cause more sensitivity.
At-Home Whitening Kits
- Lower-concentration products, such as strips or trays.
- Takes longer to see results but often causes less discomfort.
Natural Remedies
- Options like baking soda or activated charcoal.
- Less effective and safer for sensitive teeth but require caution to avoid enamel damage.
When Should You See a Dentist?
While sensitivity is usually temporary, it’s essential to consult a dentist if the pain persists for more than a week, or if you experience severe discomfort during or after whitening. Similarly, if your gums become irritated or bleed, it’s a sign to seek professional advice. A dental professional can assess your oral health and recommend suitable whitening options or alternative treatments. Taking this step ensures your safety and helps maintain your oral health during and after whitening procedures.
