Mouth Breathing: Due to various inflammatory or anatomical respiratory system problems, children in the developmental period may begin to breathe from their mouths. As the breathing becomes harder; the child begins to protrude his lower jaw while opening in order to be able to increase the air passage; the tongue is positioned on the lower jaw and the position of the lower jaw rests here. Narrowing of the palate is observed because the upper palate is not supported by the tongue. This prevents the normal development of the teeth. In time, the front teeth cannot close when the child’s back teeth are closed (open bite).
Thumbsucking: Suction impulse is very strong in all newborn babies. Babies who are not satisfied with the need to suck, start to suck their thumb in order to meet this need. It is a condition that can be encountered in every baby, and in normal circumstances, the baby leaves this habit (if not pressed to do so) spontaneously and over time. There is no need to intervene in the early period. The age of intervention should vary depending on the child. If this condition persists for 3.5 to 4 years of age, it should be intervened. Otherwise, position disturbances will occur in the teeth where the finger affects and applies force.
Pacifier: Using pacifier is a normal habit until 1.5-2 years of age. It is also a preferred way to forget the thumbsucking habit. However, it should be left after 1.5-2 years of age, otherwise, it affects the tissues and leads to the position disturbances of the teeth and the tissues.
Early Loss of Deciduous Teeth: The deciduous teeth should be kept in the mouth until the permanent tooth erupts. If it needs to be extracted due to excessive decay, then, space maintainers must be made to preserve the place after extraction. Otherwise, after the tooth is extracted, the neighboring teeth begin to move towards this space and there is no space left for permanent teeth. As a result, it causes the teeth to be positioned perplexed.
Irregularities Related to Gingival Problems: In the advanced stages of periodontal problems, especially the teeth in the front region, begin to move away from each other in the shape of a fan towards the lip. It is possible to correct the position of the teeth with orthodontic treatment after periodontal treatments.
Disorders caused by missing teeth: If for various reasons, the teeth are not replaced after the tooth is extracted, the neighboring teeth begin to tilt or move towards this space. Thus, the alignment of the teeth corrupts. When a prosthesis needs to be made, it is impossible to obtain proper results. In such a case orthodontics is the inevitable solution.
Genetic Causes: Some skeletal closing disorders are caused by genetic factors. Abnormal development of the upper jaw related to the lower jaw or the lower jaw related to the upper jaw may be caused by genetic problems.
