Key points


  • Whitening strips that contain hydrogen peroxide as the active ingredient may cause tooth sensitivity, especially after prolonged use. Hydrogen peroxide has been proven to irritate the gums and teeth, and it can even damage the enamel. 
  • Since this whitening agent destroys the enamel, the layer of yellow-coloured dentin located underneath the enamel could become more visible, making the teeth appear even more yellow over time.
  • If you want to avoid tooth sensitivity and still have a gorgeous pearly smile, you should use high-quality whitening strips such as those sold by the Icy Bear brand. Icy Bear whitening strips are made using the innovative PAP technology. These strips are much more effective than those made with hydrogen peroxide, and they don’t cause any irritation. Icy Bear whitening strips are easy to use, and what’s even better, they dissolve in the mouth on their own. So you can just apply them to your teeth and forget that they are even there.
  • Cutting back on hot and cold foods and beverages may also help reduce tooth sensitivity. Dentists also recommend choosing toothbrushes with soft bristles if you have sensitive teeth. And sonic toothbrushes are the best option if you want to prevent gum irritation and still get your teeth 100% clean every time. 


A perfect bright white smile is something we all crave to have. And what’s even better is that we can make this dream come true by using teeth whitening strips in the comfort of our home. However, not all whitening strips are formulated the same way, and it can sometimes be hard to find a product that won’t harm your teeth. 


If you’ve used home teeth whitening strips before, you may have experienced some tooth sensitivity or discomfort afterwards. That’s because many teeth whitening product manufacturers use hydrogen peroxide as the active ingredient, and it can make your teeth very sensitive. While teeth whitening products have improved over time, and now they are not as abrasive, some of them still contain high concentrations of hydrogen peroxide, which can damage your teeth. This is especially dangerous for people with sensitive teeth, which is why it’s important to choose whitening strips from reliable brands.


In this article, we will explain what causes tooth sensitivity, talk about how you can avoid or minimise the issue, and introduce you to ffective yet safe teeth whitening products that can help your teeth look white and beautiful without causing pain or sensitivity.

Why Do I Feel Pain After Using Whitening Strips?

Many people who use at-home teeth whitening products such as whitening strips complain that their teeth hurt and feel overly sensitive as a result of using these products. Tooth sensitivity usually comes in the form of a sudden rush or wave of pain. It usually occurs when your teeth come into contact with hot, cold or overly acidic foods and beverages. While dentists don’t know exactly why our teeth become sensitive, they are certain that one of the many factors contributing to this issue is worn enamel. 


As mentioned above, hydrogen peroxide is the most common ingredient in teeth whitening products. The corrosive nature of hydrogen peroxide causes damage to the tooth enamel and slowly wears it out. Thus, if you use the wrong whitening products or, what’s even worse, homemade whitening remedies, the enamel will become weak and thin. This phenomenon is known as bleaching sensitivity, and it can occur even in people who have never had an issue with tooth sensitivity in the past. This issue can cause a lot of pain and discomfort and even affect how much you enjoy your favourite foods and beverages, so it shouldn’t be taken lightly.


If hydrogen peroxide seriously damages the enamel, it can expose dentin, which is the sensitive layer of tooth tissue located underneath the enamel. This can cause dentin hypersensitivity. In this case, the mechanosensitive nerve endings in the teeth will be activated, which will result in pain. Additionally, the more dentin is visible – the more yellow our teeth appear, which essentially means that by trying to whiten your teeth with hydrogen peroxide, you make them even more yellow.

How To Avoid Tooth Sensitivity 

Tooth sensitivity is not something we want to experience when we go for a sip of delicious hot coffee or a bite of ice cream. That’s why it’s important to avoid whitening products that contain peroxide and choose safe and effective options like Icy Bear whitening strips. You can find out more about this product below. 

Use Icy Bear Whitening Strips

What makes Icy Bear whitening strips so drastically different from all the other products available in stores and online today is the technology they use. 


PAP, or phthalimido-peroxy-caproic acid, is a relatively new, non-invasive teeth whitening technology which delivers excellent results without damaging the enamel. Most whitening strips available on the market today use hydrogen peroxide to remove teeth stains, which causes tooth sensitivity. However, the PAP technology has been proven to be as effective as hydrogen peroxide but without damaging your teeth.


These whitening strips also dissolve in your mouth a few minutes after you apply them, which makes the teeth whitening process significantly easier and more pleasant, and it also saves your time, as you can just apply the strips and get going. Made for maximum customer convenience, Icy Bear whitening strips can be applied in one step without the need to use extra liquids or gels. 


These strips effectively get rid of common stains on the enamel, such as those from coffee and tea, but also protect your teeth from cavities. They can help your teeth become up to 7 shades lighter just after 14 treatments. And, of course, this product is perfect for people with sensitive teeth since it doesn’t use harsh bleaching agents and doesn’t cause or exacerbate sensitivity or irritation, unlike most other available whitening strips. Icy Bear whitening strips also don’t contain any palm oil or SLS. They are animal cruelty-free, which is a huge bonus. So order our strips today and begin your journey towards whiter and healthier teeth!


And here are some other tips that may help you with tooth sensitivity:

Cut Back On Hot and Cold Foods 

If you have sensitive teeth, it’s a good idea to reduce your consumption of cold and hot beverages as well as acidic foods. Extreme temperatures and acidic foods such as citrus, grapes, and berries may irritate your teeth and gums even more and cause even more discomfort.

Use Soft Brushes

You may be surprised, but hard-bristled toothbrushes can also contribute to tooth sensitivity and irritate your gums. If you use a manual brush, maybe it’s time for you to consider switching to a sonic device instead. Studies have shown that electric toothbrushes are more gentle on the teeth and far more effective in cleaning them than regular manual brushes. For example, the Icy Bear sonic toothbrush delivers up to 40,000 strokes every minute to help get rid of all plaque and staining on your teeth. This smart gadget also prevents you from putting too much pressure on the teeth and cleans even the hardest-to-reach areas without damaging the enamel. 

Use Toothpaste For Sensitive Teeth

Using toothpaste formulated specifically for sensitive teeth may also help alleviate sensitivity and help your teeth go back to normal. For instance, Icy Bear whitening toothpaste has been proven to strengthen the enamel while preventing staining caused by pigmented foods and beverages. It’s very gentle on the teeth and helps you to achieve a pearly white smile without causing irritation.


Does charcoal in toothpaste do anything?

Activated charcoal in toothpaste may help to remove plaque build-up and surface stains caused by coloured foods and drinks from your teeth. However, there’s no evidence to prove that charcoal actually whitens the teeth besides removing stains. In fact, it’s very abrasive and can cause abnormal sensitivity in the teeth and gums.

Do dentists recommend charcoal toothpaste?

No, generally speaking, dentists don’t recommend using charcoal toothpaste. But if you do use this product, you should be extremely cautious because charcoal is very abrasive. Plus, the American Dental Association has not found any evidence to prove that charcoal toothpaste can effectively whiten teeth. In fact, it can scrape away the enamel and make the teeth look even more yellow. This happens because charcoal exposes dentin, the yellowish layer of tissue located underneath tooth enamel.

Does charcoal toothpaste make your teeth whiter?

No, while it may seem like charcoal whitens your teeth, it simply removes plaque and extrinsic stains, just like regular toothpaste. But if you use charcoal toothpaste for a prolonged period of time, your teeth may start looking even more yellow, and you will likely experience tooth pain and sensitivity.

What’s the safest way to whiten your teeth?

We recommend using Icy Bear whitening toothpaste and whitening strips for the safest and most effective at-home teeth whitening experience. These products contain no dangerous chemicals or harsh abrasives, and they can make your teeth up to seven shades whiter while protecting your enamel and taking care of your overall oral health.
