Upper and lower teeth don’t come together, considering antimandibular, retained baby teeth, deep overjet, temporomandibular joint dislocation and so on.
1. Antimandibular: some systemic diseases or bad oral habits can lead to anterior or posterior antimandibular, which is commonly known as circumscribed or pocketed teeth, and the upper and lower teeth don’t come together.
2. Retained milk teeth: If this situation occurs during the teething period, it is considered to be retained milk teeth, which means that the milk teeth have not been lost in time and the permanent teeth have already erupted, which may be due to the fine diet or underdevelopment of the jawbone.
3. Deep overjet: the upper jaw is overdeveloped, the lower jaw is positioned backward, or the destruction of the milk molar reduces the height of the back teeth alveolus, resulting in the upper teeth cover exceeding the normal range, and from the surface, it looks like the upper teeth are blocking the lower teeth.
4. Temporomandibular joint dislocation: If the upper and lower teeth can’t close together suddenly, it is considered to be temporomandibular joint dislocation, which is usually caused by trauma, and it mainly appears that it is difficult to close the mouth, and the speech is not clear and difficult to swallow, etc. The upper and lower teeth may not close together, and it may also be difficult for the upper and lower teeth to close together.
There may be other reasons why the upper and lower teeth don’t fit together, so it is recommended that you go to the hospital in time, complete the examination to clarify the cause of the disease, and then give targeted treatment or standardized treatment.
