Gingiva has a special tissue structure. The gingival margin is not closely attached to the tooth surface, but there is a shallow groove with a depth of 0.5-2 mm, which is called gingival sulcus. Normal elbows, gums and tooth surfaces are close together, showing a closed state. The gingival sulcus is easy to accumulate food residue and plaque, which is a good area for anaerobic bacteria to grow and reproduce. Because it is closed and difficult to clean, it often leads to periodontitis. In addition, it is difficult to thoroughly clean the area below the abutment of teeth, and it is impossible to completely remove foreign bodies by brushing teeth alone, which may easily lead to periodontal disease. Some people think that it is wrong to brush your teeth carefully every day. Because new dental plaque will form within half an hour after the teeth are thoroughly cleaned, it can reach the maximum amount within 30 days, and it will turn into dental calculus over time, which can cause gingivitis, periodontitis, bleeding, bad breath, and finally lead to tooth loosening or even falling off. Therefore, if adults have not cleaned their teeth, they should go to the hospital as soon as possible to have their teeth cleaned, preferably once every six months.
What people commonly call "tooth cleaning" is medically called "tooth cleaning". The so-called "cleaning" means removing dental plaque such as bacteria, tartar and pigment from the tooth surface; And "treatment" means that it is one of the basic methods to treat periodontal disease. Inflammation of gingivitis and periodontitis can be relieved by tooth washing, but periodontal disease cannot be cured by simple tooth washing. To eradicate periodontal disease, further diagnosis and oral professional treatment should be carried out after tooth washing. So the main purpose of tooth washing is to prevent and treat oral diseases, not just to look good.
In developed countries, tooth washing has become a very popular routine oral health care, and people regularly go to the dentist to wash their teeth once or twice a year. After tooth washing, if periodontal disease is found, the dentist will conduct professional oral treatment in time to maintain oral health.
Tooth washing is a highly professional technical work. In stomatological hospital, it takes about three hours for medical staff to wash their teeth with manual instruments, and it takes about one hour to wash their teeth with ultrasonic dental scalers. According to patients, it only takes 10 minutes to clean teeth in some dental clinics or beauty salons. Practice has proved that it is very harmful to wash teeth in irregular places. First, only visible tartar is removed, leaving deep tartar with the strongest pathogenic effect, which can not achieve the purpose of preventing and treating periodontal disease. Second, the damage to the gums, especially the root exposure after tartar removal, can not be further treated in time, which not only leads to unbearable pain for patients, but also aggravates the condition of periodontal disease. Third, it is easy to cause cross-infection and bring undue regret to people. Therefore, we should carefully choose the place to wash our teeth, and go to a regular hospital to find a strictly trained medical staff to wash our teeth.
So why do teeth feel strange or allergic after tooth cleaning? After tooth cleaning, the gap between teeth is wide, will the teeth loosen? Actually, tartar is like a big cotton-padded jacket. Once you take off your teeth and expose them to a "long-lost" environment, you will have all kinds of strange feelings. If it is healthy teeth, after a period of time, the strangeness will disappear. If the gap between the teeth is large, it means that you have periodontal disease and the gums have shrunk, giving people the illusion that the gap between the teeth has widened after removing calculus. This is not caused by treatment, but the cause of periodontal disease itself. If the tartar is not removed in time, the gums will further shrink, leading to loose teeth.
