WHAT’S THE DIFFERENCE . . .

...between plaque and tartar?

-

BOTH tartar and plaque build up on the teeth and cause gum disease, but they are different substances.

Plaque is a soft, sticky film that coats tooth enamel and gums after eating.

It contains millions of bacteria which, if not properly washed away during daily brushing or flossing, will interact with food to produce acid. This can erode the tooth enamel and cause gum disease and cavities.

Tartar is hardened calcium that accumulate­s below and above the gum line when plaque is not removed. Signs of it include yellowish or brown staining on teeth.

It can cause the gums to recede, and is much tougher than plaque, requiring removal by a dentist.
