01Oral health
The Canadian Dental Association advises that bleaching is not appropriate for teeth with decay or demineralisation. Other tooth or gum concerns may need attention before an elective whitening decision.
02Pattern and possible cause
Natural ageing, foods and drinks, tobacco, tooth development, medication history, trauma, root canal treatment, and existing restorations can affect tooth colour. Different causes may respond differently or require another approach.
03Existing restorations
Fillings, crowns, veneers, and dentures do not whiten with bleaching. Lightening natural teeth can make a colour difference between the teeth and existing dental work more noticeable.
04Sensitivity and expectations
Tell the team about current or previous sensitivity and the change you hope to see. No exact shade, evenness, speed, or duration of a result can be selected from the website.
