Fitting braces is a complex and precise procedure that determines how effective the treatment will be. If braces are removed, they cannot be reused and have to be replaced with new ones, which means extra cost. Removing braces also involves cleaning the adhesive off the teeth, which can cause sensitivity. Even taking braces off for a short time can significantly delay treatment, because when they are bonded again it is often necessary to go back to earlier stages of treatment. If there is a pressing reason to remove the braces temporarily, a better option is to switch to treatment with clear aligners.
