summary

Wedge shaped defect is a kind of dental disease, which happened not long ago. So, what is wedge shaped defect? Let's talk about it.

What is wedge-shaped defect

First of all, the wedge-shaped defect is the defect caused by the slow consumption of the hard tissue in the neck of the labial buccal side of the tooth. There are many reasons for this kind of disease, mainly due to not paying attention to the correct brushing posture at ordinary times. At the same time, it is directly related to the habit of using teeth in daily diet.

Secondly, typical wedge-shaped defects are formed by intersection of two planes, some of them are composed of three planes, and a few of them are oval. The edge of the defect is neat, and the surface is hard and smooth. Generally, it is the natural color of the tooth tissue, sometimes with varying degrees of coloring. According to the degree of defect, it can be divided into three types: shallow, deep and medullary. Shallow and deep forms may be asymptomatic, and dentin hypersensitivity may also occur. Depth is not necessarily proportional to symptoms. There are pulp disease, periapical disease and even transverse fracture of teeth.

Finally, wedge-shaped defect occurs in the first premolar, which is located in the most protruding part of dental arch arc. When brushing teeth, the force is large and the number of times is large, and gingival retraction is common. Wedge shaped defects tend to increase with age. The older the age is, the more serious the wedge shaped defects are.
