There are many types of problems with the teeth and bite that orthodontic treatment can greatly improve. Usually patients will have a combination of several problems. Here are some examples of the most common orthodontic problems.
The jaw is too small or the teeth are too large to be aligned. Teeth may be turned or blocked out of the arch.
Gaps appear between the teeth.
The bite relationship is off in a horizontal manner with the upper teeth being more forward than the lower teeth. People sometimes refer to this condition as "overbite" although technically overbite refers to a vertical problem.
The bite relationship is off in a horizontal manner with the lower teeth being more forward that the upper teeth. This is also referred to as underbite and frequently patients will have a crossbite as well.
The bite relationship is off in a vertical manner and the upper teeth overlap the lower too much.
The bite relationship is off in a vertical manner and the teeth in the front do not overlap at all.
In a normal relationship, the upper teeth rest slightly on the outside of the lower. In a crossbite, an upper tooth is pushed inside the lower arch.
Anterior and Posterior
When teeth are missing, the surrounding teeth may lean into the space so that replacement of the tooth with a dental restoration is impossible. With orthodontic treatment, the teeth are ideally aligned so that the space can be restored by the dentist with a bridge
or an implant.
Sometimes orthodontic treatment can close the space and substitution of natural teeth can be used to create a pleasing and low maintenance result.
Some teeth fail to erupt and orthodontic treatment is necessary to bring them in after exposure.
