The work of 'tooth washing', that is to say, 'ultrasonic cleaning', relies on the high-frequency vibration of ultrasound to break the calculus, which has no cutting function. In addition, the doctor should constantly move the working head during operation, without pressure, and only touch the calculus gently, which will not damage the teeth. However, if the operation is improper, fine scratches will be left on the tooth surface. Generally, fine rough surfaces can be seen under the microscope. Such scratches can be made up by polishing.
2. Tooth sensitivity after tooth washing: temporarily eat less supercooled and overheated food
In addition, some patients will have tooth sensitivity after tooth washing. This is mainly because before scaling, the exposed root is surrounded by calculus, cutting off the hot and cold stimulation. In order to reduce the pain, we can avoid contact with supercooled and overheated food in a short period after scaling, so that the teeth have an adaptive process, and the symptoms will be relieved.
3. Bleeding during tooth washing: due to the stimulation of plaque and calculus
Many people have bleeding in the process of tooth washing, which is because plaque and calculus stimulate gingival inflammation. The more serious the inflammation, the more obvious the gingival bleeding. If you usually brush your teeth when bleeding, that gingivitis is not light. Only perfectly healthy gums do not bleed when they are cleaned. Therefore, it is necessary to brush teeth carefully and clear away the plaque and other irritants after tooth washing, so as to reduce gingival bleeding.
In fact, it's a 'return' of poor oral hygiene habits over the years. The original normal space of teeth is filled by gingival papilla, but due to the long-term accumulation of calculus, the gingiva will shrink, the root of teeth will be exposed, and the crevices will gradually be covered by calculus, and the crevices will be very large after removal. Once there is a gap in the teeth, it is more difficult to clean, but it is also more important. Otherwise, it is easy to attach plaque and calculus, which will further stimulate the expansion of the gap.
