Extractions in Orthodontics

Recommended tooth extractions for orthodontic purposes is a familiar method to help treat common orthodontic problems. There are multiple reasons as to why Dr. Mir may recommend extractions performed in conjunction with orthodontic treatment. Extractions can help achieve the desired outcome in many different orthodontic cases.

Crowding:

Crowding becomes apparent when there are too many teeth for the size of a patient’s dental arch. Extracting specific teeth is a common method to gain more space in the arch, allowing remaining teeth to move into the correct alignment. This method is also common when there is not enough room in a patient’s jaw for teeth to erupt.

Supernumerary (extra) Teeth:

Supernumerary teeth are extra teeth that appear in addition to the regular number of teeth. These teeth can cause impaction, meaning other regular teeth cannot erupt. This can appear in any area of a patient’s mouth and there can be single or multiple, depending on the patient.

Wisdom Teeth:

This is one of the most common extractions. Some patients dental arches simply do not have enough room for their wisdom teeth to erupt or due to the small amount of room, the teeth erupt in a crooked position. This can be harmful to surrounding teeth or cause problems with a patient’s bite. In some cases, wisdom teeth extractions may be recommended to facilitate braces. Depending on the patient’s treatment plan, extractions could be done before, during or after orthodontic treatment.

Camouflage Correction:

Like it says in the name, this method is to simply camouflage/hide skeletal deformities for patients with class 2 or class 3 malocclusion. For certain patients, this is an alternative option to skeletal repositioning. The goal of this procedure is to correct the teeth alignment without correcting the skeletal problem.

Class 2:

The objective of this treatment is to correct either severe crowding, an overbite or overjet. This is done by extracting teeth in the upper arch, allowing orthodontic treatment to move upper teeth back. This will result in a matching position of the lower teeth

Class 3:

The objective of this treatment is to correct an underbite. This is done by extracting teeth in the lower arch, allowing orthodontic treatment to move the lower teeth back.

Once again, this treatment only hides and does not actually correct the skeletal problem. Orthognathic surgery is recommended to properly correct the skeletal problem.

Age is taken into consideration when determining if extractions are a necessary part of a patient’s treatment plan. Canadian Association of Orthodontics recommend that children should have an orthodontic evaluation no later than age 7.This is because when problems are detected earlier on, the chance of needing extractions may be much lower. Dr. Mir can use other methods with fixed appliances, allowing arch expansion on younger children. Working with jaw growth and making space before teeth erupt can help avoid tooth extractions. Adults on the other hand, do not have as many options. Because their jaw has already fused, arch expansion with fixed appliances cannot be considered. Due to simply not enough room in the dental arches, it is not uncommon for adults to need 2-4 teeth removed prior to applying braces.
Dr. Mir always focuses on other treatment options before considering and presenting patients with the plan to extract teeth. If another method will provide the same outcome as extractions, Dr. Mir will always try to complete the orthodontic treatment without removal of patients teeth.
