The cost of professional teeth whitening at PhD Dental depends on the method you choose (in-office power whitening vs. take-home trays), your initial tooth colour, and whether any preparatory care is needed (such as a cleaning). During your consultation, we’ll assess your smile, recommend the best whitening solution, and provide a transparent cost estimate. While the exact amount varies by location and treatment choice, professional whitening typically offers faster, more reliable results than at-home kits.
