Invisalign clear braces are best suited to people with alignment issues such as crowded or gapped teeth. Invisalign is also suitable for both teens and adults. Considering that the teeth aligners are transparent, they might also be suitable for individuals who are self-conscious about wearing traditional metal braces. If you have severe teeth alignment issues, it is advisable to head down to a full-service clinic to determine if you are a good candidate for Invisalign treatment.
