What is the cause of dental calculus?

summary

Dental calculus is mainly on the surface of our teeth, which seriously affects our beauty. If we want to say goodbye to dental calculus thoroughly, we must first find out what causes dental calculus.

What is the cause of dental calculus?

First, saliva: saliva contains soluble acid calcium phosphate and acid calcium carbonate. When saliva is secreted into the mouth, carbon dioxide escapes, saliva becomes alkaline, the surrounding environment of plaque and soft scale alkalizes, and pH rises, soluble calcium salt becomes insoluble calcium salt and deposits.

Second, the increase of phospholipase: the normal gingival tissue contains phospholipase. When inflammation or trauma occurs, the enzyme content increases. Plaque and exfoliated epithelial cells can also release phospholipase to deposit phosphate in saliva; There is also a carbonic anhydrase, which makes saliva emit carbon dioxide and promotes the deposition of insoluble calcium salts.

Third, gel like protein escape: there is a gel like protein that exists in our saliva. It can play the role of binding calcium and phosphorus ions, and can make our phosphate maintain supersaturated state. When the colloid settles and the supersaturated state can no longer be maintained, calcium phosphate is deposited

matters needing attention

With dental calculus, to often brush teeth, it is best to develop a good habit of flossing, usually with a soft toothbrush.
