Some individuals who have their teeth whitened develop temporary tooth sensitivity, which can lead to a feeling of tingling, irritation or even pain. The problem gradually goes away, but it can be aggravating in the meantime. Certain strategies can help you prevent this sensitivity or at least reduce discomfort after whitening.
Use Gentle Products and Shorter Application Times
Rather than a 25-percent or stronger hydrogen peroxide product, use one with 5, 6 or 10 percent instead.
