Tooth Whitening - FAQTooth Whitening - FAQ
Why do Teeth Darken?Teeth can become darker for a number of reasons including:
Over the counter "bleaching" systems are of questionable value since any bleaching relies on a very closely fitting tray to hold the material to the tooth. DIY systems fail to do this and the bleaching agent may well not have been scientifically tested for safety and effectiveness. Back to Tooth Whitening FAQ What is involved?
Professional tooth whitening systems involve taking very accurate impressions of the mouth. These are then used to make very thin, customised clear plastic trays for use with the bleaching product. A small amount of whitening agent is applied as directed by the dentist. The tray is worn for 30 minutes twice every day.Within 3 to 4 days a noticeable improvement in the shade is achieved, and in 10 to 14 days the teeth are usually several shades lighter.
The process is repeated separately for the upper and lower teeth. It is possible to do the whole mouth at once but the method of doing upper then lower demonstrates the effectiveness of the shade change. Back to Tooth Whitening FAQ Is Tooth Whitening Safe?Extensive research and consumer trials in the USA and Europe have demonstrated that professional bleaching systems are safe to use. As with many procedures, it is not advised during pregnancy. Approximately 1 in 10 people may complain of sensitivity to cold during the bleaching process. This is temporary and is not a contra-indication against the bleaching process. It is important to let us know if you have sensitivity, so we may prescribe a de-sensitising agent and change the regime. It usually entails a slower process but the end result is just as successful. Back to Tooth Whitening FAQ How long does the Whitening effect last for?If your tooth whiteness is 70% of your ideal, after 10 to 14 days of whitening you will have attained ideal white which is 100%. After 2 to 3 years the whiteness may become 80-90% of your ideal. This however, can easily be topped up back to 100% ideal. Topping up can be done using the original tray and remaining bleaching material for 2 to 3 days. The bleaching material has a shelf life of approximately 4 years Back to Tooth Whitening FAQ Does it work for everyone?There are some conditions of deep discolouration, or patches of deeply discoloured enamel, that will not change very much in bleaching. This process will not whiten old fillings or porcelain work, only the original tooth. We will undertake a full assessment of your needs and advise you accordingly.
