The buildup of plaque can trap stains on the teeth, and it is also the primary factor in gum disease. Fighting plaque is a life-long part of good oral care.

Plaque begins forming on teeth 4 to 12 hours after brushing, which is why it is so important to brush at least twice a day and floss daily.

Tartar, also called calculus, is a crusty deposit that can trap stains on the teeth and cause discoloration. It creates a strong bond that can only be removed by a dental professional. Tartar formation may also make it more difficult to remove new plaque and bacteria.

Individuals vary greatly in their susceptibility to plaque and tartar. For many of us, these deposits build up faster as we age.

The photographs show the degrees of tartar (or calculus) formation.

There are many stages and forms of periodontal disease, including:

UNDERSTANDING CALCULUS
Calcium and phosphate bind to form crystals on the teeth. These calcium phosphate crystals eventually harden within plaque, forming calculus. Certain types of chemicals called pyrophosphates help to decrease calculus buildup by stopping the growth of crystals on the tooth surface and preventing new crystals from forming.

• Having your teeth cleaned professionally every 6 months, or more frequently as recommended by your dentist or hygienist
• Brushing with a toothpaste that contains pyrophosphate, such as Crest® Tartar Protection, which adheres to the tooth surface and inhibits the formation or growth of calculus crystals
• Brushing with Crest® Pro-Health or Crest® Vivid White, which contain sodium hexametaphosphate, a pyrophosphate specially formulated to not only inhibit calculus, but also loosen and break the bonds of extrinsic stains for powerful whitening and a protective barrier to prevent future stains
