Short answer: In orthodontic treatment, tooth extraction is often considered when the teeth do not have enough room in the jaw or when the front teeth and profile need to be drawn back. Not every case of crowding requires extraction; a non-extraction plan is possible for many patients. The decision is made by the dentist after evaluating records such as an intraoral examination, X-rays and photographs together.
Why does extraction come up?
The fit between the size of the teeth and the space provided by the jawbone is the basis of an orthodontic plan. If there is not enough room for the teeth, there are three routes: making small reductions between the teeth to create space, widening the dental arch, or extracting some teeth.
- Marked lack of space: When the teeth are very crowded and the jaw is small
- Protruding front teeth: When the plan is to draw the front teeth and lip profile back
- Bite relationship: When some space is needed to bring the lower and upper arches into harmony
- Poorly positioned teeth: When there are impacted or unhealthy teeth that are difficult to keep
Which teeth are extracted?
Most often one or two of the premolars (small molars) are planned, because these teeth are close to the front teeth and it is easy to make use of the space left when they are removed. In some patients an unhealthy molar or a different tooth may be chosen. Which tooth is to be extracted is determined by radiographic assessment.
How is non-extraction treatment possible?
- Interproximal reduction (IPR): Very small, controlled amounts of enamel are reshaped; for details, see our article on IPR
- Arch expansion: A narrow dental arch can be widened in suitable cases to gain space
- Distalising the back teeth: In selected cases it can be planned with mini-screw support (orthodontic mini-screws)
These methods may not provide enough space in every patient. Insisting on non-extraction in severe crowding can cause the teeth to move beyond the boundary of the bone and lead to gum problems; for this reason the limits are kept in view by the dentist.
Comparing extraction and non-extraction plans
- Space gained: Extraction provides more space, while non-extraction plans provide a limited amount of space
- Profile: With protruding teeth, extraction may allow the front teeth to be drawn back; in a non-extraction plan the teeth stay in the same position or may come slightly forward
- Duration: Because of the space closure phase, extraction treatments may take longer, but this is not true for every patient
- Reversibility of the decision: An extraction cannot be undone, so the plan is made carefully
For the factors that affect treatment duration, you can look at our article on how long orthodontic treatment takes. Our page on crowded teeth may also help with the types of crowding and treatment options.
How is the decision made?
The dentist evaluates tooth sizes, jaw width, facial profile, gum condition and growth potential together. When needed, digital scanning and a panoramic X-ray are used. The advantages and limits of the plan are discussed with the patient; in most cases more than one option is decided on together.
How does the process work after an extraction?
When an extraction is planned, it is usually carried out at the beginning of orthodontic treatment or during the preparation phase. The space that results is then closed by slow, controlled movement of the teeth. Fixed brackets or aligners can be used at this stage; if needed, supporting elements such as mini-screws come into play. For the extraction site to heal, oral hygiene should be carefully maintained and check-up appointments should not be missed.
Common concerns about extraction
- “Will my face look hollow?” Profile change depends on the bone structure and lip support; it is assessed during planning using profile photographs and X-rays
- “Will chewing become weaker?” The aim is to achieve a balanced bite after the extraction as well; plans are made accordingly
- “Will treatment take much longer?” The duration varies from person to person, so the dentist shares an estimated range after the examination
The decision to extract is made not only according to aesthetic expectations but with the health of the teeth and bone in mind.
Clear aligners and extraction
Extraction may also be needed in clear aligner treatment. Aligners can be used to close extraction spaces; however, planning this process requires care, and aligners alone may not be sufficient in every case. The dentist may suggest attachments or additional supporting elements depending on the type of movement. The decision is again made individually.
When can a second opinion be sought?
If a recommendation to extract leaves you in doubt, it is a common practice to share your records (X-rays, photographs, digital scan) with another orthodontist and get their view. What matters is understanding the reasons for the decision and being able to weigh up the options.
Frequently asked questions
Is orthodontic treatment possible without extracting teeth?
It is possible for many patients; however, if the need for space is large, a non-extraction plan may not be sufficient. This decision is made after the examination and records have been evaluated.
Will there be gaps in the teeth if an extraction is done?
The space left after an extraction is planned to be closed by moving the teeth during orthodontic treatment. The aim is for the teeth to settle into a proper bite by the end of treatment.
Does wisdom tooth extraction count as an orthodontic extraction?
It is generally a separate matter. Wisdom teeth are assessed separately because of space or position; extractions in an orthodontic plan are mostly chosen from among the premolars.
How can you find out what suits you?
The information here is general; the right plan for you is determined through an examination and the dentist's assessment. At our clinic in Oran, Çankaya, Ankara, we discuss your questions with you during the first orthodontic examination.
