Understanding Tooth Sensitivity During Teeth Whitening: Causes, Prevention, and Professional Help

Why Tooth Sensitivity Occurs with Teeth Whitening

Tooth sensitivity is a common side effect experienced by many individuals undergoing teeth whitening treatments. Understanding the underlying causes of this sensitivity can help in managing and preventing discomfort effectively. Here are the primary reasons why tooth sensitivity occurs during teeth whitening:

1. Enamel Penetration:

Teeth whitening products, particularly those containing hydrogen peroxide or carbamide peroxide, work by penetrating the enamel to reach the discolored molecules within the tooth. This process can temporarily weaken the enamel and expose the dentin layer, which contains tiny tubules leading to the tooth's nerve center, resulting in sensitivity.

2. Dehydration of Teeth:

Whitening agents can cause the teeth to become dehydrated, reducing the natural fluid content within the dentin tubules. This dehydration makes the nerves more susceptible to external stimuli, such as temperature changes, causing a sharp, sensitive reaction.

3. Pre-Existing Dental Issues:

Individuals with pre-existing dental issues, such as worn enamel, gum recession, or cavities, are more prone to sensitivity during whitening treatments. These conditions expose the dentin and nerves, making the teeth more vulnerable to the effects of whitening agents.

What Your Trained Oral Health Therapist (OHT) Can Do to Help

At Stunning Smiles, our trained Oral Health Therapists (OHTs) are equipped with the expertise to manage and mitigate tooth sensitivity during whitening treatments. Here's how they can help:

1. Personalised Whitening Plans:

OHTs can create customized whitening plans tailored to the patient's specific needs and dental health status. By assessing the condition of the enamel, gums, and overall oral health, they can recommend the most suitable whitening products and methods, minimizing the risk of sensitivity.

2. Professional-Grade Whitening Solutions:

Using professional-grade whitening solutions that are less abrasive and more effective can reduce the likelihood of sensitivity. OHTs at Stunning Smiles use high-quality products that offer optimal results with minimal discomfort.

3. Application of Desensitising Agents:

Before, during, and after the whitening treatment, OHTs can apply desensitizing agents or fluoride treatments to the teeth. These agents help to block the tubules in the dentin, preventing sensitivity and providing a protective barrier against external stimuli.

4. Guidance on Post-Treatment Care:

OHTs provide comprehensive guidance on post-treatment care, including recommendations for desensitising toothpaste, avoiding certain foods and beverages, and maintaining good oral hygiene practices to reduce sensitivity and prolong whitening results.

How You Can Prevent Sensitivity and Prolong Whitening Effects

In addition to professional care, there are several steps you can take to prevent tooth sensitivity and maintain your dazzling smile:

1. Use Desensitising Toothpaste:

Regular use of desensitizing toothpaste can help reduce sensitivity by blocking pain signals from the tooth's surface to the nerve. Look for toothpaste containing ingredients like potassium nitrate or stannous fluoride.

2. Avoid Acidic and Cold Foods:

After whitening treatments, your teeth may be more sensitive to acidic and cold foods and beverages. Try to avoid items like citrus fruits, carbonated drinks, and ice-cold treats that can exacerbate sensitivity.

3. Maintain Good Oral Hygiene:

Consistent and gentle brushing with a soft-bristled toothbrush, along with regular flossing, helps maintain the health of your enamel and gums. This practice prevents gum recession and enamel erosion, reducing the risk of sensitivity.

4. Limit Whitening Frequency:

Over-whitening can damage your enamel and increase sensitivity. Follow the recommendations of your OHT regarding the frequency of whitening treatments to avoid overexposure to whitening agents.

5. Hydrate and Protect:

Drink plenty of water to keep your mouth hydrated and help wash away any residual whitening agents. Additionally, consider using a fluoride mouthwash to strengthen your enamel and protect against sensitivity.
