The way to deal with dental calculus is to brush your teeth in a reasonable way, eat a reasonable diet, and clean your teeth regularly. 1. Reasonable brushing: Brush your teeth in the morning and evening, and rinse your mouth after meals. Recommend the Pasteur brushing method, each time brushing for 3 to 5 minutes, can assist the use of dental floss. 2. Reasonable diet: Eat more vegetables and fruits, and pay attention to the combination of coarse and fine ingredients. Avoid hard and sticky food. 3. Regular scaling: Adults can have their teeth scaled once or twice a year. Scaling includes supragingival scaling and subgingival scraping. Supragingival scaling is used to remove plaque and tartar from the gums. Subgingival scaling is used to remove subgingival plaque and tartar. The two commonly used scaling techniques are hand scaler and ultrasonic scaler. It is recommended that patients go to the hospital in time for examination and reasonable treatment under the guidance of the doctor.
