What is the difference between cracked teeth and cracked teeth

summary

First, cracked teeth, also known as incomplete teeth or teeth micro crack, refers to the surface of the crown of non physiological small cracks, often not easy to be found. Cracked teeth often penetrate into the dentin structure, which is one of the causes of toothache. The weak link of tooth structure, the large inclined plane of tooth tip and the traumatic force are the causes. Tooth fracture often occurs in the pit and fissure area of molars. It is the calcified junction area during tooth development. The tooth structure is weak due to incomplete calcification, which reduces the fracture resistance of teeth.

Second, the weak link of tooth structure is the predisposing factor of cracked teeth. These weak links not only have low anti cracking strength, but also are the stress concentration parts when teeth bear normal force. Incisors (i.e. incisors) are located in the front of dental arch, which are often cracked by external force. Wedge shaped defects often occur in the neck of lower anterior teeth and bicuspid teeth due to occlusion and cross brushing with a saw. If the more serious cases are not treated in time, it is easy to cause fracture in the neck of teeth when biting hard and tough food. The causes of the two are different, the symptoms will be different, especially in peacetime will have different performance, we must pay attention to these two situations.

Difference 3. The superficial cracked teeth often have no obvious symptoms, while the deep cracked teeth are sensitive to hot and cold stimulation, or have discomfort when occluding. Deep cleft because of the deep dentin, more chronic pulpitis symptoms, sometimes acute attack, and appear fixed-point masticatory pain. Tooth fracture is the protective reflex of the oral and maxillofacial system. It refers to the central system integration to determine the most appropriate mandibular movement without injury or with the least injury to the existing occlusion. However, in the case of pathological wear, even if there is protective reflex, it will also cause trauma due to abnormal occlusion relationship or uncoordinated occlusion force, which is bound to cause tooth fracture Cryptoschisis or tooth fracture.

matters needing attention

Teeth are very important organs in our daily life. We should pay attention to the protection, especially the habit of using teeth and hygiene. We should develop the good habit of brushing teeth in the morning and evening and gargling after eating. We should check and treat in time when there is a problem.
