Teeth cleaning is a common method of oral health care in life, which can not only help us remove stubborn tartar, but also plays a role in preventing oral diseases. However, there are still many people who are not very familiar with teeth cleaning, and even there are some misunderstandings. In view of this situation, let's introduce the common sense of teeth cleaning.
    1、 The teeth are hard to avoid dead corners
    No matter how good you brush your teeth, it is inevitable that there will be dead corners where the calculus will be formed in for a long time, especially for some people with uneven teeth, long-term smoking or tea drinking. Once the calculus is formed, it is easy to accumulate pathogenic bacteria, and then cause periodontitis. After a long time, it will affect the health of the body due to periodontitis. Therefore, it is better to clean the teeth once a year, and the patients with periodontitis who are prone to having calculus are better to clean their teeth once every six months or even three months.
    2、 Loose teeth is not caused by teeth cleaning
    This kind of situation is easy to appear in patients with more calculus. In fact, the loose teeth are not caused by teeth cleaning. These patients have serious periodontal disease, while their alveolar bone has been absorbed, their periodontal fiber has been destroyed and their teeth have been loose. Because of the splint effect of the calculus,the teeth are temporarily supported so that they are not loose at ordinary times. After the calculus is washed out, the teeth become isolated, and then you can feel the loose teeth. In fact, teeth cleaning is to remove the factors leading to teeth loosening, and then further periodontal treatment should be taken for the loose teeth.    
    3、 Pain during teeth cleaning.
    Generally, there are two kinds of pain: one kind of pain is in the process of teeth cleaning . Calculus is often gathered in the gingival margin and the neck of tooth , and the neck of the tooth is relatively weak and close to the tooth nerve, so when cleaning the teeth, you will feel pain. The other one is that after cleaning the teeth for a period of time, some people will feel hot and cold stimulation. After removal, these sensitive factors directly stimulate the dental nerve through some channels in the tooth structure, which will cause sensitive symptoms, but the symptoms are temporary and will disappear after a few days or a week or two.
    4、 Correct operation will not damage teeth
    The head of the ultrasonic cleaning machine will not damage the teeth. However, if the operation is improper, such as raising the pressure or staying in one part of the tooth for too long, slight scratches will appear on the teeth. After teeth cleaning, polishing is generally required to fix some rough surface, otherwise it is easy to have pigmentation or deposition of calculus.
