To enable the patient to perform tooth whitening at home themselves, an impression of the teeth will have to be made during the first visit to the dentist in order to produce the trays. Mouthguards will be made to individual order at a technical dental laboratory. For more information on the manufacturing of trays, read here.
After manufacturing of the tray, the dentist shall select the dental whitening agent that suits the patient’s teeth and issue a written permit for purchasing the agent. Mainly, they are special whitening gels that contain hydrogen peroxide. Hydrogen peroxide releases oxygen radicals that migrate between the prisms of the enamel, destroying the molecules that cause internal staining of the teeth.
Before going to bed, the patient presses the whitening cream into the tray to align it along the external surfaces of the teeth and inserts it in the mouth above the teeth.
The tray must be removed in the morning and the teeth must be cleaned.
One tooth whitening course usually contains up to 10 whitening sessions, which means that this procedure must be performed for 10 consecutive nights. Usually, the tooth whitening procedure must be repeated once every 1 – 2 years, when the initial tone of the teeth is restored. Increased sensitivity of teeth, which reduces within 24 hours, is common after tooth whitening.
