Teeth naturally yellow over time. Smoking and consuming drinks such as red wine, tea and coffee can also stain teeth and cause significant discolouration. The process of whitening your teeth is a great way to enhance your smile. Best of all, it’s simple and pain free and can be used in the convenience of your own home. Individual custom made trays are produced from impressions of your teeth. The whitening gel is placed in the trays and worn for an hour a day until the desired results have been achieved. The trays can then be used for top-ups as required.
