Tartar cannot be removed on its own, but when it becomes a large piece, you may be able to pick it off, but it is easy to damage the gums and may cause periodontal diseases, so it is recommended to go to the dentist to remove the calculus.
Tartar is generally very hard and cannot be removed directly by brushing.
Individuals with large pieces of calculus may be able to remove it on their own, but it is easy to cause damage to the gums and infection, and it is not clean. Remaining calculus can scrape the tongue, and also stimulate gum recession and inflammation, and there may be some periodontal effects.
Tartar should be removed with scaling to benefit periodontal health, and regular cleaning and treatment at the dentist is recommended.
