First, the dental stones of the patient who will be whitened are cleaned and polished. If the patient has cavities, fillings are applied to those teeth (the chemicals used for whitening will cause extreme sensitivity and pain in the decayed tooth, so prior treatment is essential), but it should not be forgotten that the colors of fillings, porcelain crowns or bridges will not become white with the bleaching process.
After the bleaching process, these restorations in visible areas of the mouth may need to be changed. After the patient's mouth is cavity-free and free of tartar and plaque, the physician determines the patient's tooth color with the help of scales, takes photographs and creates a record (to see how white the patient has become at the end of the procedure).
Then, a retractor (cheek-lip separator) is placed in the patient's mouth. ) is attached. In order to protect the gums, a 3-5 mm thick light-curing barrier (protector) is applied to the area where the teeth and gums meet (gingival-gum barrier). Afterwards, the active bleaching chemical agent prepared outside (hydrogen peroxide or carbamide peroxide, depending on the brand) is applied to the teeth.
The patient and the physician wear glasses to avoid being affected by the light source to be used. Then, the light device is turned on to emit light into the patient's mouth. Although it varies depending on the brand, the applied chemical is generally renewed every 12-20 minutes or mixed and irradiated again from the light source. This process is repeated 3 or 4 times. Afterwards, chemical agents on the teeth are cleaned with the help of an aspirator. The patient is asked to rinse his mouth thoroughly. Tooth color is checked.
The whitening effect will continue until 24 hours later. For this reason, it is necessary to wait 1 day to see the real effect. If necessary, other sessions are planned according to the patient's tooth color and expectations.
