Tartar removal is the act of removing tartar, composed essentially of calculus, which is formed by plaque in the mouth. It is performed by a dentist and can be done on the teeth, or also on the gums where the deposits are not visible: this is called sub-gingival tartar removal. Different techniques permit the ablation of this tartar, and are generally painless. This procedure prevents various afflictions of the gums, such as gingivitis, an inflammation of the gums. Sub-gingival tartar removal also combats bad breath and tooth loss. Even despite impeccable dental hygiene, tartar accumulates on the teeth or under the gums, which explains the necessity of a yearly checkup at the dentist to manage dental health and undergo this tartar ablation.
