No. Serious bite issues usually need traditional orthodontic treatment like braces. Invisalign works best for front teeth but it can solve many problems with crooked teeth, crowding and gaps.
Generally the cost of Invisalign is slightly higher than the cost of traditional metal braces. But the advantages of Invisalign are numerous, including comfort, ease of eating and brushing your teeth, shorter treatment time overall and the nearly invisible look.
Typically the time is closer to one year, and for some people possible a few months longer. But in some cases treatment may be completed in six to eight months.
