It can’t! There is actually no toothpaste or other daily oral product on the market that can remove tartar. Tartar is a stone-like substance that is deposited by bacteria, food debris, and saliva in the mouth over time, and it adheres to the tooth surface and even to the root of the tooth below the surface. At present, except for professional scaling and cleaning, there is no method to remove dental calculus can achieve very satisfactory results. Because calculus is very tightly attached, and its secondary site is very hidden, located in the gingival sulcus of the calculus is difficult to be detected by the patient himself, so want to remove calculus patients do not hold too many illusions, the application of toothpaste or water flossing or self-electric products can be removed on their own calculus. This idea is still unrealistic at this time. It is still recommended that patients go to a professional dentist every 0.5-1 years to have a professional cleaning, also known as supragingival cleaning, which can clean the plaque and calculus of the periodontium better through ultrasonic waves.
