A bright and radiant smile can boost one’s confidence and provide an overall sense of well-being. For those considering teeth whitening but are concerned about sensitivity, it is essential to understand the causes of sensitive teeth and the necessary precautions to ensure a successful and pain-free treatment.
In this article, we will delve into the world of sensitive teeth and teeth whitening, highlight essential factors to consider, and explain how Pickering Dental Services can help achieve a brighter smile without discomfort.
Causes of Sensitive Teeth

Understanding why teeth become sensitive will help find a solution that can lead to a more confident smile. There are several reasons for sensitive teeth, including:
1. Tooth Decay and Damaged Teeth: Cavities, cracks, or chips in the teeth can expose the underlying dentin layer, harbouring nerve endings. This exposure can lead to sensitivity and pain.
2. Gum Recession: Gums can recede for various reasons, such as periodontal disease or overzealous brushing. This recession can expose tooth roots, which are not protected by the tooth enamel, leading to sensitivity.
3. Enamel Loss: The protective enamel layer can wear away over time due to consuming acidic foods and beverages or using a hard-bristle toothbrush. The loss of this protective layer can expose dentin and lead to sensitivity.
4. Bruxism (Teeth Grinding): Grinding or clenching the teeth can wear away enamel, fracture teeth, and cause sensitivity.
Precautions to Take Before Teeth Whitening Treatment
Before undergoing teeth whitening treatment, addressing any underlying dental issues that may cause sensitivity is crucial. Some steps to take before undergoing teeth whitening include:
1. Consult a Dental Professional: Discussing concerns regarding teeth sensitivity with a dentist is essential. They will evaluate overall dental health, recommend suitable treatment options, and provide guidance for minimizing sensitivity during and after treatment.
2. Strengthen Teeth: Use toothpaste specifically designed for sensitive teeth. These toothpaste formulations can help remineralize and reinforce tooth enamel, reducing sensitivity. These products must be used consistently for several weeks before teeth whitening to observe the best results.
3. Avoid Highly Acidic Foods and Beverages: Limit consumption of foods and drinks like citrus fruits, sodas, and wine to minimize enamel erosion and reduce teeth sensitivity.
4. Switch to a Soft-Bristle Toothbrush: Using a soft-bristle toothbrush can help prevent enamel damage and gum recession, reducing teeth sensitivity.
Teeth Whitening Options for Sensitive Teeth

Once the causes for teeth sensitivity have been addressed and necessary precautions are taken, it is essential to discuss teeth whitening options with a dental professional. Some options to consider include:
1. In-office Teeth Whitening: Dental professionals use safer, controlled methods to ensure minimal sensitivity during treatment. At Pickering Dental Services, our skilled team will assess each patient’s unique situation to ensure a comfortable and successful treatment.
2. Custom-Fit Whitening Trays: Custom-made trays from a dental professional ensure optimal teeth coverage, minimizing potential sensitivity compared to over-the-counter options.
3. Desensitizing Gel: Some teeth whitening systems include a desensitizing gel that can be applied before and after whitening to minimize discomfort.
