Can Teeth Whitening Cause Permanent Sensitivity?
A popular cosmetic dental procedure, teeth whitening can brighten one’s smile and give them a boost in confidence. However, one of the common concerns among individuals considering teeth whitening is the potential for sensitivity, especially permanent sensitivity.
At Bayview Dental Arts, we pride ourselves on keeping our patients informed on all the details of their procedures. In this blog, we’ll explore the relationship between teeth whitening and sensitivity, including whether it can lead to permanent discomfort.
Understanding Teeth Sensitivity
To comprehend the impact of teeth whitening on sensitivity, it’s essential to know why teeth become sensitive in the first place. Teeth have a protective layer called enamel, which shields the more sensitive dentin and pulp beneath. When enamel wears down or becomes compromised, it can expose the dentin, leading to sensitivity.
How Teeth Whitening Works
Teeth whitening procedures, whether done professionally in a dental office or at home with over-the-counter products, generally involve the use of bleaching agents like hydrogen peroxide or carbamide peroxide. These agents break down stains and discoloration, effectively whitening the teeth.
Temporary Sensitivity
It’s not uncommon to experience some degree of tooth sensitivity during or after teeth whitening. This sensitivity is usually temporary and can manifest as a mild tingling or discomfort when consuming hot, cold, sweet, or acidic foods and beverages. This temporary sensitivity typically subsides within a few days to a week after the whitening procedure is completed.
Causes of Temporary Sensitivity
Temporary sensitivity following teeth whitening can occur for several reasons:
- Dehydration: The bleaching agents used in teeth whitening can temporarily dehydrate the teeth, making them more sensitive to temperature changes and certain foods.
- Dentin Exposure: The whitening process may temporarily open up the tubules in the dentin, allowing for increased sensitivity. However, these tubules usually reseal over time.
- Gel Concentration: Over-the-counter whitening products with high concentrations of bleaching agents are more likely to cause sensitivity than professional treatments, which are carefully administered by dental professionals.
Permanent sensitivity: Is it possible?
The good news is that permanent sensitivity as a direct result of teeth whitening is extremely rare. Teeth whitening procedures, when done correctly and under professional supervision, are generally safe and unlikely to cause lasting sensitivity. However, it’s essential to note that if you already have sensitive teeth before undergoing whitening, the procedure might exacerbate your existing sensitivity. In such cases, it’s crucial to consult with your dentist, who can recommend a suitable whitening approach or alternative treatments that minimize discomfort.
Minimizing sensitivity
To minimize the risk of temporary sensitivity following teeth whitening, consider the following tips:
- Consult a Dentist: Professional teeth whitening treatments, either in-office or take-home kits prescribed by a dentist, have a lower likelihood of causing sensitivity than over-the-counter products.
- Follow Instructions: It is vital that patients follow the instructions provided with their whitening product. Overuse or misuse can increase the likelihood of sensitivity.
- Use Desensitizing Toothpaste: Consider using desensitizing toothpaste for a few weeks before and after whitening to help reduce sensitivity.
- Avoid Extreme Temperatures: During the whitening process and shortly afterward, avoid very hot or cold foods and beverages.
- Stay Hydrated: Drink plenty of water to help rehydrate your teeth and reduce sensitivity.
