Generally, teeth misalignment can be more harmful, 80% of people may have different degrees of gingivitis, bleeding gums and calculus, and in serious cases, pigmentation of the tooth surface, bad breath or tooth decay. This is mainly due to the uneven bite of the teeth, the uneven surface of the teeth, and the poor contact relationship between the teeth, forming areas that are not easy to clean, and these areas tend to hold plaque or food debris, which is not conducive to cleaning. Misalignment can also lead to excessive biting force on individual teeth when chewing, causing an increased periodontal burden, which may lead to tooth fracture and root leakage in severe cases. In addition, it can lead to disorders of the temporomandibular joint, causing pain and popping in the joint area.
