How to Deal with Sensitive Teeth After Teeth Whitening in Cambridge?

Dec 01, 2023

Teeth whitening, a popular cosmetic dental treatment, is renowned for improving smiles and elevating self-esteem. The desire for a brighter, more radiant smile has led many individuals to explore professional teeth whitening in Cambridge, ON. However, despite the many benefits of teeth whitening, it’s not uncommon to experience tooth sensitivity as a post-treatment side effect. In this blog post, we’ll delve into the factors that contribute to tooth sensitivity after teeth whitening at Cambridge Dental Art Clinics, offer valuable advice on immediate post-whitening care, and provide home remedies to alleviate discomfort.

Causes of Tooth Sensitivity After Whitening:

  1. Whitening Agents Used: Teeth whitening gels, typically containing ingredients like hydrogen peroxide, work by breaking down and lifting stains from the enamel. While this process leads to a brighter smile, it can temporarily irritate the tooth nerves, resulting in sensitivity.
  2. Pre-Existing Dental Conditions: Individuals with pre-existing dental issues, such as gum disease or cavities, may be more susceptible to post-whitening sensitivity. These conditions can expose the tooth’s inner layers, making it more vulnerable to external stimuli.
  3. Individual Tooth Sensitivity: Some people naturally have more sensitive teeth than others. This inherent sensitivity can make the post-whitening period a bit more uncomfortable for certain individuals.

Immediate Post-Whitening Care:

In the hours and days following a teeth whitening procedure, it’s important to take steps to minimize sensitivity:

  1. Avoiding Hot and Cold Foods/Drinks: While your teeth are most sensitive immediately after whitening, it’s advisable to steer clear of extremely hot or cold items. Opt for lukewarm foods and drinks to reduce discomfort.
  2. Using Desensitizing Toothpaste: Desensitizing toothpaste, often containing potassium nitrate, is a valuable tool for alleviating post-whitening sensitivity. Brushing with this toothpaste can help block the nerve signals that cause discomfort.
  3. Rinsing with Fluoride Mouthwash: Fluoride is renowned for its ability to strengthen tooth enamel. Rinsing with a fluoride mouthwash can bolster your teeth protective layer and reduce sensitivity.

Home Remedies for Sensitive Teeth:

Managing tooth sensitivity at home can be achieved through the following remedies:

  1. Applying Fluoride Gel or Varnish: Your dentist can apply a concentrated fluoride gel or varnish, sealing off tiny channels that may transmit sensitivity. This professional intervention can provide significant relief.
  2. Using a Soft-Bristle Toothbrush: Opting for a soft-bristle toothbrush is a simple yet effective way to prevent further enamel damage. Hard-bristle brushes can exacerbate sensitivity and potentially harm the enamel.
  3. Maintaining Good Oral Hygiene: Consistent oral care, including regular brushing, flossing, and rinsing with fluoride mouthwash, is essential for reducing sensitivity and promoting overall oral health.

When to Seek Professional Help:

While some level of post-whitening sensitivity is normal, there are situations when it’s crucial to seek professional dental care:

  1. Prolonged and Severe Sensitivity: Should your sensitivity continue for a prolonged period or worsen, consulting with a dentist is crucial.
  2. Persistent Pain: Ongoing pain following teeth whitening should be addressed promptly. This could be a sign of an underlying issue that needs attention.
  3. Other Concerning Symptoms: If you experience symptoms like gum swelling, bleeding, or any unusual oral discomfort, it’s advisable to schedule a dental evaluation.

Tips to Prevent Teeth Sensitivity After Whitening:

Preventing post-whitening sensitivity is key to a more comfortable experience:

  1. Consultation with a Dentist: Before embarking on a teeth whitening journey, consult with a dentist at a dental office near you. They can assess your dental health and suggest the most suitable strategy, such as professional teeth whitening treatments.
  2. Choosing the Right Whitening Product: Professional teeth whitening procedures performed by experienced dentists are typically gentler on teeth and yield better results. Opting for high-quality products can minimize sensitivity.
  3. Gradual Whitening Approach: Instead of opting for rapid whitening, consider a gradual approach. This gives your teeth time to adapt and reduces the risk of sensitivity.


Addressing tooth sensitivity after teeth whitening is essential for a positive overall experience. By understanding the causes of sensitivity, practicing immediate post-whitening care, and implementing home remedies, you can navigate this common side effect with confidence. If necessary, seek professional help from local dentists in Cambridge, ON, including Dental Art Clinics – Cambridge.
