Dental Whitening is a cosmetic and conservative treatment that allows the degradation of dental chromogens, recovering a lighter color. This is a safe and effective procedure that can be obtained from a professional dentist. There are two types of teeth whitening: in-office teeth whitening and home teeth whitening. In office teeth whitening, a dentist applies a whitening solution to a patient’s teeth and, using a special light source, activates the solution to speed up the whitening process. In home teeth whitening, the dentist takes measurements of the patient’s teeth and creates a custom-made device, known as a “tray”, into which a whitening solution is applied. The patient wears the tray for a few hours a day for a specified period of time, usually two to four weeks, until the desired degree of whitening is achieved. Before undergoing teeth whitening treatment, it is important to consult a dentist for an assessment of your dental condition and general health. Your dentist can help choose the type of whitening that is best for each patient and ensure that it is performed safely and effectively.
