A sharp response to cold, discomfort while brushing, or a tooth that aches after whitening can have different causes. Sensitivity is a symptom to assess, not a reason to assume that every bleaching product is unsuitable or that a product labelled gentle will solve the problem. The condition of the tooth and gums determines what should happen before an elective colour change.
At Cookstown Dental Centre, we discuss your symptoms and any previous whitening experience before recommending a method. This page focuses on preparing for whitening when sensitivity already exists. Depending on the findings, the plan may involve treating a dental problem first, adjusting expectations, choosing a supervised approach, or postponing bleaching. Comfort should be part of the initial decision, with clear instructions about what to report if treatment goes ahead.
