Is there any harm in getting teeth extracted for orthodontic treatment?

Why do you have to pull out perfectly good teeth in order to straighten teeth? Will the other teeth become loose after a tooth is pulled out? Can the teeth be aligned without pulling any teeth? The debate over whether or not teeth need to be pulled out for orthodontic treatment has long been a focus of concern for many people. Some people who originally planned to undergo orthodontic treatment back out once they hear that teeth will need to be pulled, giving up on the opportunity for correction and even missing the appropriate time for treatment. Whether or not teeth are pulled, whose opinion counts? Let's take a look at how the experts explain it, so you don't get stuck on the issue of tooth extraction in orthodontics.

Firstly, these questions related to tooth extraction often make parents hesitate about whether their children should receive treatment during consultations for orthodontic correction. In fact, this is not something to worry about. Tooth extraction for orthodontic purposes has been tested by clinical practice throughout the history of the development of orthodontics. Teeth are removed to provide enough space to align the teeth. If there is severe crowding and no teeth are removed while trying to force alignment, the corrective effect will be very unstable. Even if the teeth are aligned, they are likely to revert to their original deformity. Tooth extraction in orthodontic treatment is not done blindly; it requires comprehensive consideration of factors such as the arrangement of the teeth, the upper and lower jawbones, facial appearance, and analysis based on data provided by dental models and X-rays. Especially among Asian populations undergoing orthodontic treatment, tooth extraction is quite common due to the characteristic protrusion of the mid-face in Asians. Sometimes, tooth extraction can provide space to help align the teeth neatly while also improving the overly prominent appearance of the mid-face.

Secondly, parents often worry about whether the other teeth will become loose after a tooth is extracted. Healthy normal teeth are each independent and will slowly move under the influence of corrective forces. This is a process of biological remodeling and will not harm the teeth, similar to how wounds naturally heal. If there is tooth looseness, it is due to the tooth's own disease, mainly periodontitis, and not caused by tooth extraction.

Finally, within the field of orthodontics, there have always been two views regarding tooth extraction. Whether supportive or opposing, both are only targeted at those borderline cases where extraction may or may not be necessary. Doctors who support tooth extraction believe that extracting teeth can achieve better jaw shape and stability of treatment effects, while those who oppose extraction believe that through methods like palatal expansion accompanied by alveolar bone remodeling, good results can still be achieved. With the advancement of modern corrective techniques, especially the use of osseointegrated implants, an increasing number of borderline cases can be corrected without tooth extraction and achieve ideal results. Considering various factors such as the degree of crowding of the teeth, the aesthetics of the jaw face, doctors will analyze and choose a reasonable plan. One thing that will not change is the treatment goal of orthodontics: perfect tooth alignment, stable corrective effects, and good chewing function.

Additionally, another important point is the removal of wisdom teeth after orthodontic treatment is completed. Wisdom teeth, which are the third molars at the end of the tooth row, generally erupt after the age of 16. If there is insufficient space when they erupt, it can lead to impacted wisdom teeth, a phenomenon that is relatively common among today's youth. Impacted wisdom teeth can exert continuous forward pressure on the tooth row, potentially causing misalignment, especially re-crowding and displacement in the lower front tooth area. Therefore, early removal of wisdom teeth is not only crucial for maintaining the results of correction but can also prevent the occurrence of pericoronitis.
