The main method of orthodontic treatment to correct crowded and crooked teeth is through orthodontic treatment. However, there are different approaches for different ages. Orthodontic treatment is mainly the use of braces to correct dental problems. The use of brackets is the most common way to correct malocclusions, these braces are fixed and can only be removed by the doctor and the aligners cannot always be taken out for the best results. Alignment of braces is mainly an alternative to fixed braces, this is a type of appliance that can be removed, this treatment is mainly used to treat malocclusion problems without carrying food debris and plaque, this approach is mainly for adults with slightly spaced teeth and is not applicable to the treatment of children and adolescents. Removable instruments are used to treat children. This type of instrument is best suited to treat children between the ages of 8 and 10 years old, and is mainly performed on the child’s own condition. This approach is not as wide as it should be in the upper arch and often uses palatal dilators. So this approach is mainly used to treat children. Although there is one main approach to treatment, there is still a treatment that will correspond to the age of the patient. So it is important to treat the condition as it is so that the best treatment results can be achieved.
