Nowadays, more and more people are aware of the importance of “scaling” for dental health, but in clinical practice, many people will ask doctors whether there will be “tooth damage”, “tooth sensitivity”, “bleeding gums” and “larger gaps” after scaling. However, in clinical practice, many people ask doctors whether there will be “tooth damage”, “tooth sensitivity”, “bleeding gums” and “larger gaps” after scaling. In fact, the ultrasonic scaling head itself does not have any cutting function, it relies on the high frequency vibration of ultrasonic waves to break the tartar, and the doctor has to keep moving the head when operating, and there is no pressure, but only gently touching the tartar, so it will not damage the teeth. However, if the operation is not proper, such as pressure or staying on the tooth surface for too long, it will leave tiny scratches on the tooth surface, which is usually visible under the microscope as a fine rough surface, and such scratches can be made up by polishing. Some people will feel soreness of teeth during scaling, which is mainly due to root exposure, which is a typical manifestation of periodontal disease. Tooth roots are more sensitive to cold, hot, sour, sweet and other stimuli. Therefore, the more severe the periodontal inflammation, the more obvious the root exposure may be, and the more obvious the soreness in the treatment will be. Tooth sensitivity after scaling: temporarily eat less cold and hot food In addition, some patients may also experience tooth sensitivity after scaling, which is mainly due to the fact that before scaling, the exposed tooth roots are surrounded by tartar, isolating hot and cold stimuli. To reduce the pain, avoid contact with too cold or too hot food for a short period of time after scaling, so that the teeth have an adaptation process, and the symptoms will be relieved. Bleeding during scaling: due to stimulation from plaque and tartar Many people have bleeding during scaling, which is due to inflammation of gums stimulated by plaque and tartar, etc. The more serious the inflammation is, the more obvious the gum bleeding is. If you bleed when you brush your teeth normally, it means that the gum inflammation is not light. Only completely healthy gums will not bleed during scaling. Therefore, if you insist on brushing your teeth carefully after scaling to remove plaque and other irritants, you can reduce gum bleeding. The problem of larger gaps after scaling also distresses many people, but in fact, this is the “reward” of poor oral hygiene habits over the years. The normal gap between teeth is filled by the gum papillae, but due to the long-term accumulation of tartar, resulting in gum atrophy, the root of the tooth is exposed, and the gap is gradually covered by tartar, which will appear to be a large gap after removal. Once teeth have a gap, cleaning is more difficult but also more important, otherwise plaque and tartar will easily attach and stimulate the gap to become further larger.
