Clean teeth good? 8 Why about cleaning teeth

Question: Why is it said that cleaning teeth can prevent periodontal disease?
As we all know, dental caries (that is, tooth decay) and periodontal disease (often manifested as bleeding from brushing teeth, loose teeth, etc.) are the two most important oral diseases that plague human beings, both of which are mainly caused by plaque bacteria. Because some people do not develop good oral hygiene habits, do not brush their teeth in the morning and evening or do not brush their teeth in the correct way, the food residues in the mouth will combine with the inherent flora in the mouth to form plaque on the surface of the teeth. If it is not cleaned in time, plaque will combine with calcium and phosphorus ions in human saliva and calcify into calculus. The two are the main culprits of most toothaches, bad breath, bleeding gums, loose teeth, etc.
For the plaque and calculus that have already formed, brushing can do nothing. Tooth cleaning can remove the plaque, calculus and pigment deposited on the tooth surface attached to the junction of teeth and gums, so as to remove local pathogenic factors, stop the development of gum damage and restore to a relatively healthy state.
Second question: Why is it said that cleaning the teeth is basically harmless to the teeth?
Generally speaking, the enamel and cementum on the surface of the teeth are very hard. Whether it is manual mechanical scaling or ultrasonic scaling, the calculus can be easily removed with appropriate force or strength, and no strong removal is required. Therefore, it will not harm the teeth. People who have problems with their teeth should actively receive dental restoration treatment after cleaning their teeth.
In addition, the working head of ultrasonic scaling itself does not have any cutting function. It relies on the high-frequency vibration of ultrasonic waves to break the calculus, and the doctor has to move the working head continuously during operation, and there is no pressure, but only lightly touch the calculus. Will not damage teeth. However, if the operation is improper, such as pressing or staying on the tooth surface for too long, it will leave small scratches on the tooth surface. Generally, the fine rough surface can be seen under the microscope. This kind of scratches can be compensated by polishing.
Three questions: Why choose a regular hospital for teeth cleaning?
In the process of cleaning teeth in informal hospitals, the gums may be damaged, especially if further professional treatment cannot be carried out in time when the roots of the teeth are exposed after removal of tartar, which not only causes unbearable pain for patients, but also aggravates the condition of periodontal disease. In addition, it may only remove the visible tartar, leaving the deepest tartar with the strongest pathogenic effect, which cannot achieve the purpose of preventing and treating periodontal disease. More importantly, it is easy to cause cross-infection, which brings undue regret to people.
In regular oral medical institutions, the diagnosis and treatment equipment is generally “one person, one use and one disinfection”, and the chances of patients contracting diseases are very small. Therefore, the place to clean your teeth should be chosen carefully, and you should go to a regular hospital to find a strictly trained medical staff to clean your teeth for you.
Question 4: Why do I need to polish my teeth after cleaning?
Because after scaling, the surface of the teeth is not smooth, and there are often leftover pigments and tiny calculus that are difficult to distinguish with the naked eye. Under the catalysis of calcium salts in saliva, the calculus will be deposited faster than before, and it must be polished with The device polishes the tooth surface and makes the teeth bright, in order to achieve the purpose of delaying pigmentation.
In order to save costs, informal dental clinics usually only do preliminary cleaning work, and save the step of polishing the tooth surface. Therefore, informal tooth cleaning is generally cheaper, but it is very easy to produce calculus again.
Five questions: Why do some people choose to use laughing gas when cleaning their teeth? The scientific name of “laughing gas” is nitrous oxide, which is a colorless and sweet gas, and can make people laugh, hence the name “laughing gas”. This gas does no harm to the human body. It is a good analgesic and anesthetic and is very suitable for oral treatment. It has a history of more than 150 years in Western countries. Now 76.5% of oral institutions in the United States have oral “laughing gas”. Pain relief system. When using the “laughing gas” pain relief device, just wear a mask and inhale lightly, basically just like we normally inhale oxygen. The effect is fast, generally 30 seconds after inhalation of nitrous oxide, and the best effect can be achieved in 5 minutes.
After inhaling nitrous oxide, it can quickly produce analgesic effect and relieve anxiety. The patient can be sedated, stay awake, relaxed and comfortable throughout the treatment process, respond to verbal instructions, cooperate with mouth open, and actively cooperate with treatment, and then cooperate with anesthetics. It can be painless, making the treatment process more humane and safer. For cleaning teeth, it is very suitable for patients with a lot of dental calculus or emotional tension and fear.​​
Sixth question: Why should women have a dental cleaning before preparing for pregnancy?
New research has found that the importance of pregnant women’s oral health is reflected in the impact on the next generation. Studies have shown that unhealthy oral health of pregnant women can harm the fetus, and periodontal disease can lead to premature and low birth weight babies. In addition to periodontal disease, pregnant women are also susceptible to dental caries during pregnancy.
Under normal circumstances, after pregnancy, the frequency of meals increases, sweets and delicate foods increase, and the pH in the oral cavity changes. If you do not pay attention to oral hygiene, it is easy to develop caries. Therefore, oral examination and preventive treatment should be done before pregnancy. The teeth that should be treated are cured, the teeth that should be extracted are pulled out, and the teeth that should be inlaid are inlaid.
Therefore, it is very important to clean your teeth. It is recommended that women should clean their teeth in advance before pregnancy to prevent oral problems from being passed on to the baby.
Seven questions: Why is it not suitable for cleaning teeth during menstruation?
In menstrual women, blood coagulation is reduced, and heavy bleeding may occur if teeth are cleaned. In addition, women during menstruation are more sensitive to pain and have poor resistance. At this time, dental treatment is more painful and prone to infection.
Eight questions: Why is not everyone suitable for teeth cleaning?
People with bleeding disorders, such as patients with thrombocytopenia and leukemia, have poor blood coagulation mechanism and are prone to bleed more after cleaning and are not suitable for cleaning. People with acute infectious diseases, such as active acute hepatitis, tuberculosis patients, etc., should wait until the disease is stable before going to the hospital for cleaning.
Patients suffering from infectious diseases such as hepatitis and tuberculosis should truthfully explain their situation to the medical staff before cleaning their teeth, and doctors can give special care to such patients. Patients with active angina pectoris, myocardial infarction within six months, and uncontrolled hypertension and heart failure are not suitable for routine dental cleaning. If the heart is equipped with an artificial pacemaker, it is not suitable for ultrasonic cleaning.
