Mouthwash cannot handle tartar. Tartar is not easily removed by mouthwash when it forms and must be professionally scaled in a hospital. There are two types of scaling: supragingival scaling and subgingival scaling. 1. Supragingival scaling is the main way to remove plaque and tartar from the gums. There are two types of cleaning methods, including hand scalers and ultrasonic scalers. This method removes fine calculus debris from the surface of the teeth and reduces the re-attachment of plaque and calculus to the surface of the teeth. 2. Subgingival scaling is used to remove subgingival plaque and tartar. This method can remove bacteria and tartar from periodontal pockets. It is always recommended to go to the hospital for further examination in time, according to the results of the examination and under the guidance of the doctor.
