Hello, braces usually take about one to three years. The length of time mainly depends on the patient's age and the severity of the dental problem to be solved. Generally, children need less time to correct, and the treatment effect is better, mainly because their teeth are not fixed and are easier to correct. However, because the adult orthodontic teeth have been basically shaped, it takes longer to achieve the same therapeutic effect, and the retainer should be worn for a longer time after treatment to avoid rebound. Another reason is the severity of dental problems. If the teeth are uneven, the treatment time will be longer.
