One of the side effects of teeth whitening is that it can make the teeth feel a little sensitive for a few days post-treatment, especially if the patient already experiences sensitivity in their teeth or gums. Certain foods and drinks that are very hot or cold can bring out sensitivity in the teeth, as can eating very sweet foods.
