How to deal with tooth sensitivity after whitening

A bright, white smile is something that many of us strive for, and for good reason. Not only does it make us feel more confident, but it can also make us look more attractive and approachable. However, for some people, achieving that perfect white smile comes with a downside – tooth sensitivity. If you’ve recently undergone a teeth whitening treatment and are now experiencing sensitivity, don’t worry – there are ways to deal with it. 

In this blog post, we’ll go over some tips and tricks for managing tooth sensitivity after whitening.

Understanding Tooth Sensitivity

Tooth sensitivity is a common problem that affects many people, especially after teeth whitening. The sensitivity is caused by the removal of the tooth’s protective layer, which exposes the sensitive dentin layer underneath. When this layer is exposed, the nerves in the teeth become more sensitive to hot and cold temperatures, as well as acidic and sugary foods.

It’s important to note that not everyone will experience tooth sensitivity after whitening. Some people may have a higher tolerance for the whitening process, while others may have more sensitive teeth to begin with. Additionally, the type of whitening treatment you undergo can also affect how sensitive your teeth become.

Tips for Managing Tooth Sensitivity After Whitening

Before your appointment, it is important to discuss your options with your dentist or oral surgeon. There are different types of anesthesia available for the procedure, including local anesthesia, IV sedation, and general anesthesia. Your dentist or oral surgeon will help you choose the best option based on your needs and preferences.

  • Use a Sensitive Toothpaste One of the easiest ways to manage tooth sensitivity after whitening is to switch to a toothpaste that is specifically designed for sensitive teeth. These types of toothpaste contain ingredients that help to block the tiny tubules in your teeth, which can help reduce sensitivity. Look for toothpaste brands that contain potassium nitrate or stannous fluoride, as these are the most effective ingredients for reducing sensitivity.
  • Avoid Hot and Cold Foods and Drink As mentioned earlier, tooth sensitivity can be exacerbated by hot and cold temperatures. If you’re experiencing sensitivity after whitening, it’s a good idea to avoid foods and drinks that are very hot or very cold. Stick to room temperature or lukewarm foods and drinks, and avoid anything that is too extreme.
  • Limit Your Consumption of Acidic Foods and Drinks Acidic foods and drinks can also make tooth sensitivity worse. Try to limit your consumption of things like citrus fruits, vinegar, and carbonated beverages. If you do indulge in these foods and drinks, rinse your mouth out with water afterward to help neutralize the acid.
  • Use a Soft-Bristled Toothbrush Using a toothbrush with hard bristles can actually cause more damage to your teeth and gums, and make sensitivity worse. Instead, opt for a soft-bristled toothbrush that is gentle on your teeth and gums. Be sure to brush gently, and avoid applying too much pressure.
  • Consider a Desensitizing Gel If your tooth sensitivity is particularly severe, you may want to consider using a desensitizing gel. These gels contain a higher concentration of the same ingredients found in sensitive toothpaste, and can be applied directly to your teeth to help reduce sensitivity.
  • Talk to Your Dentist If you’re still experiencing tooth sensitivity after trying these tips, it’s important to talk to your dentist. They may be able to recommend additional treatments or procedures that can help reduce your sensitivity and make you more comfortable.


Tooth sensitivity after whitening can be a frustrating and uncomfortable side effect. However, with the right approach, you can manage your sensitivity and still enjoy the benefits of a bright, white smile. By using sensitive toothpaste, avoiding extreme temperatures and acidic foods, using a soft-bristled toothbrush, considering a desensitizing gel, and talking to your dentist, you can minimize your sensitivity and keep your teeth healthy and happy.
