If teeth become sensitive during whitening, it can be tempting to push through to the desired shade or switch products without guidance. Neither response establishes why the discomfort is happening. Bleaching-related sensitivity and gum irritation can occur, but a localized or persistent symptom may have another cause that needs examination.
At Cookstown Dental Centre, we review what you are using, how it is applied, and the pattern of discomfort before advising on the next step. This page focuses on comfort during and after an assessed whitening course. It complements the pre-treatment assessment described under Teeth Whitening for Sensitive Teeth; the two titles describe related aspects of care, not different procedures. The goal is a clear response plan that respects both the cosmetic aim and the condition of your teeth and gums.
