Tartar cannot be removed at home by yourself, especially do not use baking soda or rubbing agent to rub the surface of the tartar vigorously, which will lead to excessive scratches on the surface of the teeth, but instead cause the tartar to continue to increase. The best way to remove tartar is to go to the hospital and have a professional dentist perform an ultrasonic cleaning. Ultrasonic cleaning requires a certain technical approach from the doctor, and it is not something that can be done by the patient at home, nor is it something that can be done by a non-professional instead. This is because some of the tartar is located in the gingival sulcus, which requires a certain technical approach. If tartar remains on the surface of the teeth for a long time, it may cause the gums to recede. If the patient himself has excessive tartar, he must go to the hospital in time for treatment.
