Can clear aligners fix crowded teeth?

Many spacing cases can be treated with braces or aligners, but the cause of the gap matters. Missing teeth, tooth size differences, gum health and bite relationships can change the plan. A gap between the upper front teeth, for example, can be linked to a low-attached frenum, and teeth that are small for the arch leave generalised spacing. Closed gaps have a tendency to reopen, so a retainer is an important part of the plan, and some patients are also offered tooth-coloured bonding to even out tooth widths.

Adults can usually have orthodontic treatment if their teeth, gums and bone support are healthy enough. Adult plans may need closer attention to gum health, existing dental work and long-term retention. Adult teeth move more slowly than a teenager's because the bone is denser and growth has finished, so treatment can take somewhat longer, and gum disease must be controlled before it starts. Many adults choose aligners or ceramic or lingual braces because they are less noticeable at work.
