Tooth washing, also known as tooth cleaning, refers to the use of cleaning equipment to remove calculus, plaque and stains on the gum, and polish the tooth surface to delay the deposition of plaque and calculus. Plaque and calculus are the main local stimulation factors of periodontal disease. Scaling is the most effective method to remove supragingival plaque and calculus. So is tooth washing harmful? How much is a tooth wash
1. Note that the main purpose of tooth washing is to prevent and treat tooth diseases, not just to look good.
The porous structure of dental calculus is also easy to absorb a large amount of bacterial toxins, and dental calculus will hinder brushing. If it is not removed for a long time, it may cause gingivitis, periodontitis, gum bleeding, halitosis, and finally tooth loosening or even falling off. Therefore, tooth washing plays a protective role.
2. Because of eating some food and colored drinks, some pigment will accumulate on the teeth. In people who smoke for a long time and like to drink dark drinks, the deposition of pigment is especially obvious, which has a great adverse effect on the appearance of teeth. These pigments are also removed during supragingival scaling. However, because the tooth surface is not as smooth and smooth as the mirror surface, it is impossible to completely remove the pigment. There will always be some pigment residues on the denture of the tooth surface.
Polishing is a necessary step in tooth washing. After cleaning, it is necessary to polish the tooth surface with rubber cup and polishing paste, so as to slow down the attachment of plaque and the formation of calculus.
3. So, how to wash your teeth?
Teeth washing can be divided into manual cleaning and ultrasonic cleaning according to the different instruments used. Manual cleaning is to use different types of manual cleaning machine for operation, while ultrasonic cleaning is to use ultrasonic cleaning machine for operation.
4. Hand cleaning
The disadvantage of hand cleaning is obvious, that is, it takes time and effort. It usually takes about 3 hours to complete the manual cleaning of the whole teeth. For patients with particularly many calculus, they even need to complete it in several times. In this process, patients need to keep their mouth open. Long time mouth opening is very uncomfortable for patients, and long time operation is a kind of torture for doctors. Therefore, in clinical practice, the application of manual scaling is less and less, instead of ultrasonic scaling.
However, hand cleaning has its advantages. For doctors, the hand feeling of hand cleaning is better, and the existence of calculus can be more truly felt. The power of hand cleaning is soft, and there is no water spray during the operation, so the patients will not have strong discomfort, and the chance of cross infection in the diagnosis room will be reduced.
5. Ultrasonic scaling
The ultrasonic cleaning machine is composed of an ultrasonic generator and a transducer. The generator sends out electromagnetic vibration and amplifies the power. The transducer converts high-frequency electric energy into ultrasonic vibration. The vibration frequency reaches 20000-45000 Hz. The calculus attached to the tooth surface is removed by the high-frequency vibration of the working head on the transducer. The working head of ultrasonic dental cleaner has many shapes, such as sharp round type and flat type.
In addition, there is a sprinkling system on the ultrasonic cleaning machine. When the ultrasonic vibration of the working head is started, the spray system will spray water to the working head and form an aerosol. On the one hand, it will play the role of cooling head, and the other important aspect is the formation of cavitation, that is, there is a thin vacuum bubble collapsing rapidly in the droplet of spray, which produces energy, and produces erosion effects on dental calculus and plaque. The broken calculus and blood washed away.
The advantage of ultrasonic scaling is time-saving and labor-saving. Generally, it can complete the supragingival scaling of the whole teeth in an hour or so.
6、 About the common mistakes of washing teeth:
1. Some people think that if you brush your teeth carefully every day, you don't need to wash your teeth. This is wrong.
2. Some people think that healthy teeth are pure white, just like the teeth of models in toothpaste advertisements. In fact, this is wrong. The structure of normal teeth is a transparent enamel containing light yellow dentin
3. Correct tooth washing is not harmful to teeth.
4. Tooth washing will cause the gap to become larger, which makes many people refuse to wash their teeth. In fact, the accumulation of calculus and gingival inflammation will cause the local swelling of gingiva to fill the gap, and the calculus will be removed after tooth washing, and the gingival swelling will gradually subside, so the gap will become obvious
5. After removing calculus by teeth washing, the teeth will be exposed to the long-term outside environment, which will produce various different feelings. In the case of healthy teeth, this sensitive symptom usually disappears gradually within one to two weeks after tooth washing. So it doesn't cause tooth sensitivity.
Therefore, in the process of tooth cleaning, it does not have the effect of cutting, cutting and grinding, so naturally there is no problem of tooth wear.
7. What is the harm of tooth washing?
As for teeth washing, we must find a professional hospital. Because professional hospitals do not cause harm.
However, non professional hospitals will certainly cause some unnecessary harm.
1. In general, non professional dental cleaning only pays attention to the removal of visible tartar, leaving the deepest tartar with the strongest pathogenic effect, which can not achieve the purpose of prevention and treatment of periodontal disease.
2. It is easy to damage the gums by non professional tooth washing,
3. It is easy to cause cross infection.
8. What's the price of a tooth wash?
If it's a common way to wash teeth, the price of washing teeth in small cities is about 20 to 30 yuan, but it's a little more expensive in big cities, about 100 to 400 yuan
1. The price of ultrasonic tooth washing is generally around 120
2. The price of sand blasting and tooth washing is generally around 160
3. The price of tooth polishing is generally around 100
Matters needing attention
Some patients are not suitable for ultrasonic cleaning. Patients with infectious diseases such as tuberculosis, hepatitis B antigen positive, HIV infection and other patients disable the ultrasonic cleaning machine, because the spray generated will pollute the operating area and surrounding environment.
Remember to go to a regular hospital.
Remember, there is no harm in washing your teeth just like washing your face with water. Of course, irregular operation will cause adverse consequences.
