The following are some of the issues that, depending on the brand, can be corrected with clear aligners:

Overcrowding of the teeth (overlapping teeth)

Overbites (upper front teeth overlap with the lower front teeth)

Underbites (lower front teeth overlap with the upper front teeth)

Diastema (small or large gaps between the teeth)

Open bites (front upper and lower teeth slant outward and do not touch when the mouth is shut; a rare type of malocclusion)

Baby teeth that are crooked or misaligned in their sockets (phase I orthodontic treatment; children between 6 and 10 years of age are candidates for this treatment)
