Will you lose your teeth after washing your teeth? Does washing your teeth hurt your teeth? Introduc

Tooth washing is a way to protect teeth, which is not harmful to teeth. The technical term supragingival scaling refers to the use of scaling instruments to remove calculus, plaque and color stains on the gums, and polish the tooth surface to delay the re deposition of plaque and calculus. Dental plaque and dental calculus are the main local irritants of periodontal disease. Scaling is the most effective method to remove supragingival plaque and dental calculus.

Methods and advantages and disadvantages of tooth washing:

According to the different instruments used, tooth washing can be divided into manual scaling and ultrasonic scaling. Manual scaling is operated by different types of manual scalers, while ultrasonic scaling is operated by ultrasonic scaler.

1. Manual scaling

The disadvantage of manual scaling is obvious, that is, it takes time and effort. Usually, it takes about 3 hours to complete the manual scaling of the whole mouth of teeth. For patients with a lot of calculus, it even needs to be completed in several times. In this process, patients need to keep their mouth open. Long time mouth opening is undoubtedly very uncomfortable for patients, and long-time operation is a kind of torture for doctors. Therefore, in clinical practice, manual scaling is less and less used, and ultrasonic scaling is replaced.

However, manual scaling also has its advantages. For doctors, manual scaling feels better and can more truly feel the presence of dental calculus. The power of manual cleaning is relatively soft, and there is no water spray during the operation, so the patients will not have a strong sense of discomfort, and the chance of cross infection in the clinic will be reduced.

2. Ultrasonic scaling

The ultrasonic tooth cleaning machine is composed of an ultrasonic generator and a transducer. The generator emits electromagnetic oscillation and amplifies the power. The transducer converts high-frequency electric energy into ultrasonic vibration with a vibration frequency of 20000 to 45000 Hz. The calculus attached to the tooth surface is removed through the high-frequency oscillation of the working head on the transducer. The working head of ultrasonic dental cleaning machine has a variety of shapes, such as sharp circle type and flat type. The appropriate working head can be selected according to the size and position of dental calculus.

In addition, there is a sprinkling system on the ultrasonic cleaning machine. When the ultrasonic vibration of the working head is started, the water spraying system simultaneously sprinkles water at the working head to form an aerosol. On the one hand, it plays 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. And wash away the shattered dental stones and blood stains.

The advantage of ultrasonic scaling is time-saving and labor-saving. Generally, the supragingival scaling of whole teeth can be completed in about an hour.

After ultrasonic scaling, the probe shall be used to carefully check whether there are missing dental calculus. If there are some small dental calculus and adjacent dental calculus, it shall also be removed with manual instruments.

In addition, some patients are not suitable for ultrasonic scaling. 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.

Patients with respiratory diseases should not use ultrasonic scaling machines, such as patients with respiratory depression and patients with chronic lung disease. Generally, patients wearing cardiac pacemakers are forbidden to use ultrasonic dental cleaning machine to avoid arrhythmia and other symptoms caused by interfering with the work of pacemakers.
