This kind of defect is composed of two inclined plane intersect a "groove", defect is neat, hard, smooth surface, like a wedge, thus known as "wedge-shaped defect.
The formation of the teeth "scar" with brushing way closely related. Because, the tooth neck of tooth enamel and bone at the junction of the structure of the organization is relatively weak, and the transverse equivalent mechanical friction brushing your teeth, like a see-saw, long-term cause tooth wear. Plus the exudation of acid corrosion in gingival sulcus, creates this kind of like a wedge shaped defect.
In old people more opportunities to form a wedge-shaped defect, because as we age, oral degenerative change, gingival recession lead to tooth neck exposed, "battleground" just this area more friction.
According to the characteristics of the wedge-shaped defect formation, must stress damage, the higher the possibility of big teeth.

This is one of the reasons for the elderly of, so we should pay attention to the correct method of brushing your teeth.
Cai Huaxiong reminds, wedge-shaped defect prevention is the most important is to choose the suitable toothbrush, and master the correct method of brushing your teeth. Toothbrush bristles not too hard, the diameter of the brush head with a coin size advisable, cutting-edge best through grinding processing. When brushing your teeth up and down movement of the vertical brush method, absolutely avoid horizontal brush forever.
