Can whitening the teeth cause sensitivity?
It some cases, it does. Quick-bleaching processes, particularly the in-office two-hour whitening, can lead to sensitivity. We believe this is due to the tooth getting “dried out” during the process. It is usually transient and there are things that can be done to reduce or relieve it. Anecdotally, it appears that home-bleaching might not result in as much sensitivity, particularly when used properly.
