The technical term for scaling is called scaling, which uses ultrasound or manually to remove tartar and plaque from around the teeth (tartar and plaque are the main causes of bleeding gums and periodontal disease,) and also makes the mouth visually clean and odor-free (which is one of the signs of civilization), so scaling must be done once every six months to a year, and it is mandatory by insurance in the United States, so 50% of the work of dentists in the United States is to do scaling. In our country, there are now more people doing regular cleanings, but many people still have concerns that ultrasonic scaling is damaging to their teeth, and some people have the experience of tartar accumulating faster after scaling. This is because ultrasonic scaling will leave shallow scratches on the tooth surface, if not polished, it will be easy to accumulate tartar, so you must polish with a rubber cup with polishing paste after scaling, many unregulated clinics or hospitals do not do polishing. In conclusion, scaling is good for the health of your teeth and not bad, but always remember to have your dentist polish your teeth after scaling.
