Texas State Board Of Dental Examiners Still Require Dental Offices To Follow COVID Emergency Rules And Still Require Everyone To Wear A Mask Regardless Of Governor Ruling

Picture this: you just got your teeth whitening done, and now you’re looking forward to a picture-perfect smile — only to realize you have increased sensitivity. It is not uncommon to have teeth sensitivity after whitening, but it is only temporary. But why does it happen in the first place? Keep reading this blog to learn more!

Why Do I Have Teeth Sensitivity After Whitening?

When you undergo teeth whitening, the dentist will use gels that temporarily turn your dental enamel permeable. This means your dentin layer is exposed for a short period, where the teeth nerves are present. Slight discomfort and sensitivity after whitening might take place since your teeth are in a vulnerable state.

Teeth whitening procedures also involve bleaching gels, which results in irritation and sensitivity. Moreover, whitening trays are another popular method of attaining a brighter smile, but it exerts a force on your teeth, which causes sensitivity.

How Long Does Teeth Sensitivity After Whitening Last?

Generally, teeth sensitivity after whitening lasts around two days. The resulting discomfort is due to the chemicals and bleaching agents used during teeth whitening treatments. But there is a silver lining: the sensitivity is only short-lived. Two days later, you can feel confident and smile brightly with your enhanced teeth!

Tips to Prevent Sensitivity After Teeth Whitening

Although the teeth sensitivity after whitening is not extreme, some individuals may have a low tolerance for the discomfort. In that case, the following tips might help:

  1. Avoid Hot & Cold Triggers: Exposure to foods and beverages with hot or cold temperatures triggers sensitivity. Thus, take a break from extreme temperatures initially after the procedure.
  2. Steer Clear of Acidic Foods & Drinks: Citrus foods, sodas, and other acidic food content can irritate your teeth and cause discomfort.
  3. Use a Desensitizing Toothpaste: A desensitizing toothpaste or gel can significantly improve the symptoms after teeth whitening.
  4. Brush Gently: Your teeth enamel is already in a vulnerable state; brushing in an aggressive manner only makes things worse. You should practice gentle brushing in general, but more so after teeth whitening.
  5. Invest in Fluoride Products: You can incorporate fluoride in your dental routine, which strengthens your teeth by remineralizing them. This reduced teeth sensitivity after whitening!


You can brighten your smile with teeth whitening, but it might cause sensitivity for a few days. Regardless of the reason, teeth sensitivity after whitening is only temporary and will go away in around two days. If not, you can talk to a dental specialist!
