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: normal gingival tissue contains phospholipase. When inflammation or trauma occurs, the enzyme content increases. Dental plaque and exfoliated epithelial cells can also release phospholipase to deposit phosphate in saliva. There is also a carbonic anhydrase that releases carbon dioxide from saliva to promote insoluble calcium deposition.

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, making 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.
