[Gwangjin-gu Dental Clinic] 3 Stages of Orthodontic Treatment for Oral Health and Well-Aligned Teeth

Hello, this is Gwangjin-gu Dental Clinic, S (S) Leader Dental Hospital.

One of the factors that shapes a first impression is a smile. But what makes that smile shine even more is not simply appearance, but healthy, well-aligned teeth. When teeth are evenly arranged, brushing becomes much easier, which helps prevent cavities and gum disease, reduces unnecessary strain on the temporomandibular joint, and allows chewing to function properly.

On the other hand, when teeth are not aligned, small inconveniences can build up and lead to gum bleeding, tooth wear, jaw pain, and even speech problems. For this reason, orthodontic treatment is not just a procedure done “to look better,” but an important choice for protecting oral health throughout life.

So, how does orthodontic treatment proceed?

It is completed through three major stages: diagnosis, tooth movement, and retention.

Precise diagnosis and customized treatment planning

The beginning of orthodontic treatment is a “thorough diagnosis.” It is not possible to judge simply by looking at crooked teeth with the naked eye. In addition to the patient’s tooth alignment, the position of the jawbones, the relationship between the upper and lower teeth, and harmony with facial features must all be analyzed to establish the right treatment direction. During this process, X-rays, oral photographs, dental impressions, or data collected with a 3D oral scanner may also be used.

In particular, adolescents who are still growing require even more detailed analysis because it is necessary to predict how the jawbones will develop, whether extractions are needed, or whether growth control appliances would be beneficial. For adults, jaw growth has stopped, so the range of tooth movement must be calculated in detail, and the condition of the gums and the health of the tooth roots must also be considered.

At this stage, the orthodontist creates a customized treatment plan that reflects the patient’s lifestyle, occupation, and aesthetic preferences. For example, if the patient has many public-facing activities and prefers not to wear noticeable appliances, clear aligners may be suitable. If more precise movement is needed, bracket-based orthodontics may be recommended. In this way, the diagnostic stage is the blueprint for orthodontic treatment, and the entire process can proceed stably only when this foundation is solid.

The process of appliance attachment and tooth movement

The second stage is the core of orthodontic treatment: tooth movement. At this point, various appliances are selected depending on the patient’s condition, such as metal brackets, ceramic brackets, self-ligating brackets, or clear aligners. Once the appliance is attached, the teeth gradually move within the bone thanks to the bone’s remodeling process. The bone in the direction the tooth is moving is resorbed, while new bone forms on the opposite side, allowing the tooth to slowly shift to the desired position.

During this period, patients usually notice the greatest changes. When first wearing the appliance, the gums may feel pulled or pressured, and chewing may feel uncomfortable. However, most patients adapt within a few days, and during regular visits, the medical staff makes fine adjustments to tooth movement. The important thing is oral hygiene management.

Because orthodontic appliances structurally make it easy for food particles to get trapped and create an environment where bacteria can multiply, more thorough brushing than usual is necessary. Use orthodontic toothbrushes, interdental brushes, and dental floss to care for them carefully, and if needed, fluoride solution can be used to further help suppress bacteria.

Also, lifestyle habits should be handled carefully during this period. Hard or sticky foods should be avoided because they can damage the appliance, and habits such as nail biting or teeth grinding can interfere with the orthodontic effect, so caution is recommended.

Retention appliances and aftercare that complete orthodontics

The final stage is “retention.” Many patients think treatment is over once the orthodontic appliance is removed, but in fact, that is when the most important process begins. Because teeth have a tendency to return to their previous positions, a retainer must be used to hold the newly established alignment in place.

Retainers can generally be divided into removable retainers and fixed retainers. Removable retainers are transparent plastic appliances that can be taken out and put back in conveniently, but their effectiveness depends on how consistently the patient wears them. Fixed retainers, on the other hand, involve attaching a wire to the back side of the teeth, so they are less noticeable and can maintain a steady effect.

The retention period varies from person to person, but it usually requires at least 1 to 2 years, and in some cases, retainers must be worn for a longer period. What matters at this stage is regular checkups. Aftercare should be carried out by periodically checking whether the tooth alignment remains stable and whether there is any strain on the gums or the temporomandibular joint. Only by following this process well can the results of orthodontics last for a long time, allowing you to enjoy healthy teeth and a proper bite throughout life.

Precise diagnosis to aftercare: orthodontics you can trust

Orthodontic treatment is only complete after going through these three stages: diagnosis, tooth movement, and retention. It is not simply about creating straight teeth, but about protecting oral health and delivering a confident smile.

S Leader Dental Hospital carefully analyzes each patient’s teeth and jawbone condition, and based on extensive clinical experience, establishes the optimal orthodontic plan. Even after treatment is finished, we work together through ongoing aftercare so that patients can maintain healthy teeth and a smile for a long time. If you are considering orthodontics, it would be a good idea to receive an accurate consultation at a clinic equipped with expertise and a systematic system.
