Types of professional whitening
Home whitening uses custom trays made from impressions of your teeth, worn for a few hours a day or overnight for two to four weeks. In-chair whitening is done at the practice in one or two visits. Many practices combine the two.
Is teeth whitening safe?
Whitening by a GDC-registered professional is safe for most people. Temporary sensitivity is common. Whitening does not change the colour of crowns, veneers or fillings, so these may need replacing to match.
About Teeth Whitening
Professional teeth whitening is the safest and most effective way to brighten your smile. Unlike over-the-counter products, professional treatments use higher concentrations of whitening agents under dental supervision.
