Wisdom tooth caries symptoms?

summary

Dental caries is a medical term that refers to tooth decay or decay. Dental caries is caused by the erosion of enamel by acidic substances. There are many different types of bacteria in the mouth. These bacteria (together with saliva, food residue and other natural substances) constantly gather on the surface of teeth to form a layer of mucous membrane, which is called dental stains.

Wisdom tooth caries symptoms?

Shallow caries, also known as enamel caries, is limited to enamel. In the early stage, the plaque was chalky due to demineralization on the smooth surface, and then it was yellowish brown due to coloring. The pit and fissure were infiltrated and diffused. Generally, there was no obvious caries cavity, only rough feeling when probing. In the later stage, there were shallow holes limited to enamel, no self-conscious symptoms, and no response to probing.

The caries of the middle caries has reached the superficial layer of dentin. There are obvious caries holes in clinical examination, and there may be pain probing. There may be pain response to external stimuli (such as cold, hot, sweet, acid and food embedding). When the stimulus source is removed, the pain disappears immediately, and there is no spontaneous pain.

Deep caries has reached the depth of dentin, generally manifested as large and deep caries cavity, or the entrance is small and deep with extensive damage. The response to external stimulation is more serious than that of moderate caries, but after the removal of stimulation source, it can still relieve pain immediately without spontaneous pain.

matters needing attention

Drug therapy is a method to inhibit the development of dental caries on the basis of grinding caries. It is suitable for the shallow caries of permanent teeth and the shallow and medium caries of deciduous anterior teeth. Commonly used drugs include silver nitrate and sodium fluoride.
