The best time to treat a geodesic is between the ages of 3 and 4, but the timing of treatment should be considered in the context of the patient’s actual condition. When children are 3-4 years old, they have relatively good bone elasticity. At this time, orthodontic treatment is not only conducive to bending and deformation of teeth and other plastic changes, but also less likely to break or crack during the process of wearing braces. In addition, when the child enters this age, the degree of cooperation with treatment is relatively high, which can better correct the jaw position and achieve more ideal treatment results. However, for patients who have already entered the permanent phase of edentulism, it is recommended that patients can choose to undergo orthodontic treatment around the age of 12-14. During this period, the patient’s roots have stabilized and the dental radiographs allow for better observation of root development and a more appropriate orthodontic treatment plan. During the treatment period, the patient should pay more attention to oral hygiene and health care, regularly visit the dentist for follow-up examinations, and reduce the consumption of hard, candy and other types of food.
