The length of time it takes to correct alignment or bite problems with the teeth will depend on what the problem is, only the orthodontist is able to decide when the teeth have been properly corrected. In many cases the length of time that the braces must be worn has been shorten with the new applications. These appliances while unobtrusive are also aggressive when it comes to aligning the teeth properly.
In many cases the amount of time that braces must be worn is much less than with traditional braces, the amount of time they are worn also is less painful than with braces in the past. While they aggressively begin to align the teeth no matter what type of braces they are will still take time to correct the dental problem and even after the teeth are corrected it is often suggested that the braces stay on for an amount of time to ensure that none of the teeth will shift once they are taken off.
Each person that needs their teeth corrected is different and because the teeth are different an orthodontist cannot say that each patient will wear their braces for a certain amount of time. In many cases it will also depend on age as many adults now wear braces and it will take longer to correct the alignment of an adult than it does a child or teenager whose bones are still growing and it will also depend on the problem of the adult teeth or bite.
