A history of sensitivity does not automatically rule out whitening. It does mean the dentist should know about it before treatment starts. Sensitivity-management options can include desensitizing products and changes to the whitening approach. Philips also provides products specifically intended to help manage sensitivity associated with Zoom whitening. Its published materials recommend desensitizing toothpaste before some in-office treatments and describe Relief ACP as a sensitivity-management product. A dentist may also take existing sensitivity into account when deciding how the treatment should be performed. The aim is not simply to push for the fastest possible color change. The condition of the teeth and the patient’s comfort both belong in the conversation.
