For tartar, no toothpaste can be used to remove tartar. Tartar is a tartar-like substance that is deposited layer by layer by plaque in the mouth and adheres closely to the tooth surface, especially in the gingival sulcus. The best treatment at present is scaling treatment, and the generally said brushing application of dental floss, toothpicks, and the current hotter water floss cannot achieve a better removal of calculus. Because calculus is very strong and located within the gingival sulcus, which is difficult for patients to reach on their own, it is important not to have illusions about removing calculus, but to go to a professional dentist for dental scaling treatment.
