What is the reason why teeth can't close together

If you observe your teeth carefully, you will find that your teeth are relatively neat, and the teeth bite together very tightly. However, some people find that their teeth cannot close together, and there will be large gaps between their teeth when they bite together. This is not only inconvenient when eating, but also affects their appearance, so timely correction is needed. So, what is the reason why teeth cannot close together?

The harm of misalignment of upper and lower teeth

1. Impact on oral health: Crowded and uneven teeth make it impossible for teeth to clean themselves, plaque and calculus accumulate, causing caries and inflammation of the gums and periodontium; at the same time, misaligned teeth and abnormal occlusion can also cause periodontal damage; sparse teeth can easily cause food impaction and damage the health of the gums and periodontium.

2. Impact on facial appearance: Various types of malocclusion affect facial appearance to varying degrees, which is also the direct reason why many patients request correction. Such as open lips and exposed teeth, bimaxillary protrusion, long face or short face deformity, etc.

3. Impact on maxillofacial development: During the growth and development of children, many dental and maxillofacial deformities caused by bad habits will affect the normal development of the soft and hard tissues of the maxillofacial region. For example, anterior crossbite, commonly known as "underbite", refers to the deformity of the lower front teeth being located on the lip side of the upper front teeth, which will restrict the development of the maxillary bone. The mandible develops excessively forward due to the lack of normal coordination, thus forming a mid-face depression and excessive protrusion of the mandible. Therefore, the anterior crossbite that affects the development of the upper and lower jaws should be corrected as early as possible to avoid further aggravation of the jaw deformity.

4. Impact on oral function: Severe malocclusion can affect the normal function of the oral cavity, such as open bite of the front teeth (i.e. the upper and lower front teeth cannot bite together) causing abnormal pronunciation, lockjaw of the back teeth affecting chewing function, severe mandibular protrusion causing abnormal swallowing, and severe mandibular retraction affecting respiratory function.

5. Impact on mental health: Uneven teeth seriously affect children's growth and development and cause psychological disorders. Data show that the incidence of psychological disorders increases among adolescents with malocclusion. Not talkative and lacks confidence.

What should I do if my baby's upper and lower teeth cannot bite together?

It is understood that the healthiest tooth arrangement is: both upper and lower teeth are neat; the front teeth cover normally (the upper teeth cover the lower teeth by 1-3mm); the upper and lower teeth have 2mm of overbite; and the occlusion of the back teeth (incisor and molar) is a cusp-to-fossa relationship. Parents are reminded to pay attention to their children's teeth. They should take their children to the hospital for a check-up by an orthodontist every six months so that problems can be discovered at any time and treated in time.

Misalignment of the upper and lower teeth is harmful to children. For the future growth of children, it is recommended that parents should take their children to the hospital for a detailed examination at this time. According to the occlusion of the upper and lower teeth of the child, decide whether to correct the deformity, how to perform the teeth correction, etc., and cannot ignore the growth of the child's teeth.
