Calculus is a type of hardened plaque that forms on teeth. This plaque is made up of food debris, bacteria, and saliva. Over time, calculus can build up and become difficult to remove. If not removed, calculus can lead to gum disease and tooth decay.

Dental calculus forms when plaque is not removed from teeth. Plaque is a sticky film of food debris, bacteria, and saliva. When plaque is not removed, it hardens and becomes calculus. Calculus can be yellow or brown in color and is usually found along the gumline. If not removed, calculus can lead to gum disease and tooth decay.

Types of Calculus:

There are two types of calculus: supragingival and subgingival.

1. Supragingival Calculus  is the type that forms above the gum line, on the visible surfaces of your teeth. 

2. Subgingival Calculus  forms below the gum line, in the pockets around your teeth where you can’t see it. 

Both types of calculus can cause problems if they’re not removed.

Supragingival calculus is easier to remove than subgingival calculus because it’s more accessible. Your dentist or dental hygienist can usually remove supragingival calculus during a routine cleaning. Subgingival calculus is more difficult to remove and may require special instruments or procedures.

How to remove Calculus from teeth:

There are many ways to remove calculus from teeth without going to the dentist.

  • One way is to use a toothbrush designed to remove calculus. These toothbrushes have special bristles that are able to reach into small spaces and loosen plaque. There are also toothpastes and mouthwashes that can help remove calculus.
  • Another way to remove calculus is to use home remedies. Home remedies can include using baking soda, hydrogen peroxide, or vinegar. These substances can help break down plaque and calculus.


If you have calculus on your teeth, it’s important to see a dentist or dental hygienist for regular cleanings. They can remove the calculus and help you prevent future build-up.
