There are several techniques for teeth whitening but in the last decade the "at home" method of whiteneing has become the most widely used and most successful. This technique utilizes a plastic tray, which is made by the dentist to fit comfortably over the patient's teeth for 2-3 hours per day, for several weeks, as the effects of the whitening process takes place.
Several whitening kits can be bought over the counter, But it must be realised by the patient that the dental professional will not directly supervise the majorty of the whitening activities. Because of this, anyone bleaching their teeth must be certain that the specific whitener they are using is safe and that they know how to use this product. Failure to use the correct product or follow the instructions could result in damage or harm the teeth and/or gums.
WHO CAN PERFORM TOOTH WHITENING
Teeth whitening is a form of dentistry and should only be performed by a dentist or another regulated dental professional, such as a dental hygienist or dental therapist, on the prescription of a dentist.
