Details.
The procedure consists of four 15-minute whitening intervals. Before treatment, the soft tissues of the mouth are isolated to protect the gums and other areas inside the smile. A bleaching solution is applied to the teeth and activated with blue LED light. Teeth should be cleaned and gums should be in good health before professional whitening to optimise the result. The most common side effect is tooth sensitivity. Maintenance options include custom-made trays with peroxide solution or a Zoom three per cent at-home pen.
