How to Whiten Sensitive Teeth

You shouldn't have to compromise on achieving a brighter, whiter smile due to teeth sensitivity issues. With the right approach and products, you can effectively whiten your teeth while addressing sensitivity concerns. In this comprehensive guide, we'll explore how to navigate teeth whitening with sensitivity, ensuring a radiant pearly white smile without discomfort.

Understanding Sensitivity and Whitening

Tooth sensitivity is a common side effect of whitening. The main reason for this discomfort is due to the bleaching agent, typically hydrogen peroxide or carbide peroxide. This causes a chemical reaction on the tooth surface that increases the porosity of the enamel thus making your teeth sensitive. This discomfort can be pronounced or heightened if you have existing conditions like enamel erosion, exposed dentin, or gum recession. However, by adopting the right strategies (and products), you can minimize sensitivity while still achieving noticeable whitening results.

Go Slow and Space Out Treatments

First and foremost, it's essential to approach teeth whitening with sensitivity in mind. Try to avoid in-office treatments or products with high concentrations of peroxide, typically over 10%. These strong formulations can exacerbate sensitivity and cause discomfort. Instead, opt for gentler whitening methods, like some at-home whitening solutions that has a lower concentration of bleaching agent and space out treatments to once every several days. By allowing your teeth time to adjust between sessions, you can mitigate sensitivity and achieve gradual whitening results.

Consistency Is Key

Whitening your teeth when you have sensitivity requires patience and consistency. This journey is not a quick fix but rather a gradual process. Commit to a regular whitening routine and stick to it over time. Consistency is crucial for minimizing sensitivity and ensuring long-lasting results. Remember, slow and steady progress is better than rushing and risking discomfort.

Choosing the Right Products and Ingredients

When selecting whitening products for sensitive teeth, it's essential to prioritize ingredients that address sensitivity while effectively whitening your smile. Look for products that offer these approaches to reduce sensitivity:

  1. Dulling the Nerves: You can choose products containing ingredients like potassium nitrate, arginine and stannous fluoride. These compounds work by desensitizing the nerves in your teeth, reducing discomfort during whitening treatments.

  2. Blocking Access to the Nerves: You can opt for products containing hydroxyapatite, a natural mineral that helps occlude or block the tiny tubules in your teeth. This prevents external stimuli from reaching the nerves, minimizing sensitivity.

  3. Sensitive Toothpaste: You can use a toothpaste specifically geared towards addressing sensitivity issues. For example, Ollie offers a range of oral care products designed specifically for individuals with sensitive teeth. Their sensitive toothpaste combines potassium nitrate and hydroxyapatite, providing dual-action relief for sensitivity while promoting enamel remineralization. After brushing be sure to leave a residue of toothpaste on your teeth (don’t rinse), especially before bedtime, to maximize its effectiveness.

Avoid Ineffective Ingredients

Be cautious of whitening products that claim to be sensitivity-free but lack effective whitening agents. Ingredients like bromelain, PAP, or other alternatives to peroxide may have some whitening effect but may not effectively whiten your teeth and could lead to disappointment. Stick to proven ingredients backed by scientific research for safe and effective whitening.


Whitening your teeth with sensitivity requires a tailored approach and the right products. By going slow, choosing gentle formulations, and prioritizing sensitivity-reducing ingredients, you can achieve a brighter smile without sacrificing comfort. In my opinion, with products like Ollie's whitening strips and toothpaste, you can confidently embark on your whitening journey, knowing that your smile is in safe hands.
