The tooth jaw root should be the tooth palatal root, the cause of which may be related to the excessive occlusal force, palatal root machine expansion root canal treatment, palatal root into the staking nail.
1. Excessive occlusal force: because the molar teeth bear almost all of the masticatory occlusal force, so in the exercise of the masticatory function, there will be uneven force, which can lead to the maxillary molar palatal root fracture phenomenon.
2. Palatal root machine expansion root canal treatment: clinically, when the tooth suffers from apical inflammation, it is often necessary to carry out root canal treatment. Nowadays, a large number of machine-expanded instruments are used to accelerate the speed of root canal preparation, but they also remove too much tooth tissue and change the normal root canal curvature of the tooth root, which can easily cause palatal root fracture in the exercise of mastication.
3. Staking in the palatal root: Sometimes the defect is too big to be repaired directly, so a staking is often done in the palatal root, which is covered with resin material to fill the restoration. In the process of chewing, the palatal root may be loosened and broken due to the excessive twisting force of chewing.
There are other reasons why the palatal root of the tooth breaks, you should consult a doctor in time, improve the examination, by the stomatologist to carry out targeted treatment.
