1. Before whitening teeth, it is necessary to prepare related items: the main items to be prepared are: water for mouthwash, paper towels, strong suction, perforated towels and towels for disinfection. Mainly used for cleaning before whitening and disinfection after whitening.
2. Debugging of the sandblasting machine for whitening: This is an important step before whitening. The doctor needs to determine whether the sandblasting machine is suitable for the patient before whitening. You can mainly use your palm to perceive the intensity of sandblasting. It should be noted that the amount of sand in the sandblasting machine must be sufficient, and the ratio of water and sand must also be moderate, so as to achieve the best whitening effect.
3. Determine the key parts of sandblasting: the sensitive parts of the patient are mainly the lip surface of the upper front teeth and the lingual surface of the lower front teeth. To target these two sensitive parts, the sandblasting machine needs to be aimed at the key injection.
4. Sandblasting teeth cleaning: Before the formal teeth cleaning, the handpiece and the long axis of the teeth should be at a 45-degree angle, and sandblasting should be performed towards the incisal end and maxillofacial surface of the teeth, and it should be done without interruption, 2-3 minutes. It will end after that. After cleaning, the doctor can ask the patient to wash his face with a towel in order to keep it clean.
