What's the most harmful effect of biting each other at night? What's the most harmful effect of biting each other at night. Children's nocturnal molars are common, which may play a certain role in occlusal construction, promote normal growth and development, adjust and form a good occlusion.
1. The effect on the tooth and pulp tissue
Bruxism is the most direct effect of bruxism, which causes extensive loss of tooth tissue, destruction of tooth shape and sharp edge. It can often stab the soft tissue of lip, cheek and tongue, shorten 1 / 3 of the face, and age, which affects the beauty and pronunciation of patients.
2. The effect on temporomandibular joint was as follows
Temporomandibular joint, masticatory muscles and occlusal teeth are a functional whole. Bruxism destroys the morphology and function of the occlusal system. It can also cause masticatory muscle dysfunction, such as masticatory muscle hyperfunction, spasm, fatigue, pain and so on. Imbalance of muscle contraction, abnormal occlusal position, change of vertical height between jaws, and maladjustment of disc process position also directly affect the normal morphology and function of temporomandibular joint, showing abnormal mandibular movement, joint bounce, and muscle pain.
3. Head and face pain:
Bruxism patients often have facial pain, headache, as well as maxillofacial muscle fatigue and other reactions. Severe patients may have persistent pain, even chewing, biting, yawning, speech pain.
