It takes about 2 years to straighten teeth with braces, and the exact amount of time will depend on each individual’s situation. If the patient is in adolescence or adolescence, this is the best time for orthodontic treatment because the bones and teeth in the mouth are more malleable, so it is easier to correct and may take about 1 year to complete. If the patient who needs orthodontic treatment is older, the bones of the teeth are basically set and it is more difficult to straighten them, which may take 2 years or more. The time needed varies depending on the malformation of the teeth in the patient’s mouth. If only 3 or 4 teeth are malformed and the degree of malformation is not serious, it is faster to correct. If all the teeth in the mouth are severely malformed, it may take longer to correct the malformation as it may require tooth extraction or other procedures.
