Yunnan Baiyao toothpaste is not able to remove tartar. In fact, there is no toothpaste that has a better effect on the removal of calculus. Calculus is a long-term mixture of bacteria, food debris and saliva in the oral cavity and the deposition of calculus-like substances, it will be firmly attached to the tooth surface, especially in the gingival sulcus, except for professional scaling, there is no 1 way to remove calculus can achieve very satisfactory results. This is due to the fact that calculus is firstly very tightly attached, and secondly its main presence is very hidden, and it is very difficult for patients to detect calculus located in the gingival sulcus itself. Therefore, to remove calculus, patients should not have too many illusions that they can remove it on their own by applying toothpaste or flossing, which is currently unrealistic. To remove calculus, it is still recommended that patients go to a professional dentist every six months to a year for a professional scaling treatment, which is what we usually call supragingival scaling, which can clean the plaque and calculus of the periodontium better through ultrasonic waves.
