What's the best dental cure for a teeth full of tartar?

A full mouth debridement may be advised. If there is bacterial infection and gum disease, scaling & root planing may be advised.

Deep Clean: See your dentist for an exam and a good cleaning to get the calculus (tartar) off. It will not come off with brushing alone. It is calcified plaque, mineral, and food debris that allow colonization of bacteria and will lead to periodontal disease which is bone loss and recession.
