There are dental and bony types of deviated jaws, which usually need to be determined by dental examination and taking X-rays. Deviation refers to the asymmetry between the left and right sides of the upper and lower jaws, and in some cases, the teeth may be skewed, causing facial asymmetry and affecting chewing, pronunciation, and so on. There are both dental and bony deviations. Usually it needs to be determined by dental examination and taking X-rays. If the dental examination reveals that the upper and lower jaw teeth centerline deviates from the maxillofacial centerline, and the X-ray film shows that the left and right sides of the jawbone are symmetrical, then it is mainly a dental deviation. If the X-ray shows that the left and right sides of the jaws are not symmetrical, then it is mainly a bony deviation. In case of deviation, it is recommended to go to the hospital in time, after completing the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
