Dental Calculus
Calculus, also called tartar, is plaque that has hardened on the teeth. Plaque is a soft film of bacteria that forms every day, and when it is not removed by brushing and cleaning between teeth, minerals in saliva can harden it into a rough, yellowish or brownish deposit. Calculus is most often found near the gum line and behind the lower front teeth, where saliva glands are close by.

What to know about Dental Calculus
Calculus cannot be removed by brushing at home once it has hardened. A dentist or hygienist removes it with scaling instruments, then checks the gums for irritation or early gum disease. Regular cleaning helps prevent new calculus from building up, and it also gives a dentist a chance to spot gum problems early.

Frequently asked questions about Dental Calculus
What is the difference between plaque and calculus?
Plaque is a soft film that brushing can remove. Calculus is plaque that has hardened, and it needs professional removal.
Can I remove calculus at home?
No. Once plaque has hardened, home brushing will not remove it, and scraping at it can injure the gum.
Does calculus cause gum disease?
Calculus itself irritates the gum and makes cleaning harder, which can contribute to gum problems over time.
