Glossary Term: Dental Calculus or Tartar

By Janet Tobiassen Crosby, DVM, About.com

Definition: Pronunciation Key: Tar'-Ter

Tartar is a hard, yellowish deposit on teeth. It is composed of mineral salts, food, and other debris that has hardened over time. Tartar cannot be brushed off. It has a rough surface, attracting more debris and food particles, causing a repeating cycle of tartar formation and buildup.

If your pet has tartar on the teeth, your veterinarian will likely recommend a thorough dental cleaning to remove the tartar and polish the roughened tooth surfaces.
