No, whitening your teeth should not hurt.
Short-term cold sensitivity is normal.
Whitening does not harm your teeth. However, it can make them sensitive to cold liquids in the short term. This sensitivity will go away with time.
If you experience sensitivity, whiten less often.
For patients who are more prone to cold sensitivity, we recommend whitening your teeth less often and for shorter periods of time. If you choose to have professional whitening or bleaching at our office, we will create a customized protocol based on your tooth sensitivity.
Certain toothpastes can help.
Certain kinds of toothpaste, such as Sensodyne, contain fluoride and potassium nitrate which helps decrease tooth sensitivity.
