If it is food residue or other soft tartar with low adhesion that exists on the tooth surface, patients can use mouthwash, brushing and flossing to remove it. However, for stubborn tartar and calculus, it is difficult to remove them by oneself, so it is recommended to go to the regular hospital dentistry department for removal in time. If it is tartar attached to teeth for a long time, it may mineralize and form calculus, and calculus attached to teeth or around teeth for a long time may cause gingivitis, bleeding gums, periodontal disease and other oral diseases, so it is recommended that patients regularly go to the dental hospital for scaling and cleaning to remove calculus, such as using instruments or ultrasonic waves to clean teeth. At the same time, scaling can also whiten the teeth and improve certain aesthetic appearance. Patients are advised to pay attention to oral hygiene and to brush or rinse their teeth reasonably and correctly in the morning and after meals to reduce the retention of tartar on the surface of the teeth. All aspects of the teeth and between the teeth should be cleaned at ordinary times to reduce the generation of calculus. Patients are advised to minimize the consumption of coffee, strong tea, acidic beverages and other beverages that may cause harm to the teeth, and to avoid smoking as much as possible to reduce the formation of calculus. Sweeter or more sticky foods are more likely to adhere to the surface of the teeth, increasing the possibility of calculus production, and need to be reduced.
