Protruding Teeth
Protruding teeth usually refer to the upper teeth that stick out and can be classified into dental protrusion and skeletal protrusion.
-
Dental protrusion involves flaring of the front teeth and can often be effectively corrected with conventional orthodontic treatment.
-
Skeletal protrusion occurs when the upper jaw itself is protruded rather than just the teeth. Traditionally, this type required surgical intervention for correction.
With advancements in dental technology, even skeletal protrusion can now be improved through non-surgical aesthetic orthodontic techniques. This approach not only eliminates the need for complex surgery and avoids cutting into the upper jaw, but also reduces the risks associated with general anesthesia.

When is the Right Time for Orthodontic Treatment?
Non-surgical aesthetic orthodontics differs from traditional methods, as it focuses on both the teeth and jaw structures.
The effectiveness of treatment primarily depends on the current condition of the teeth, rather than age.Generally, the optimal age for orthodontic treatment is around 12 years old.
However, the most important factor is whether the individual—or their parents—feel there is a problem; a dental examination should be scheduled as soon as concerns arise.Nowadays, the proportion of adult orthodontic patients is increasing.
Compared with children, adult treatment requires special attention to periodontal health. As long as the gums and supporting tissues are healthy, orthodontic treatment can be performed.Other factors, such as bone structure and age, should also be considered.
Therefore, adult orthodontics differs from pediatric treatment and requires careful planning and evaluation. -
The term periodontal disease may not be unfamiliar, but it is worth explaining in detail.
“Periodontal” refers to the tissues surrounding the teeth—the structures that support and stabilize them. These include:
-
Gums (gingiva)
-
Periodontal ligament – fibers that attach the tooth root to the alveolar bone
-
Alveolar bone – the bone that houses the tooth sockets
-
Cementum – the calcified tissue covering the tooth root, allowing attachment of the periodontal ligament
If any of these tissues are affected, it is referred to as periodontal disease.
Regular dental cleaning helps reduce the risk of periodontal disease. After orthodontic treatment, maintaining good oral hygiene habits not only keeps teeth clean but also lowers the risk of cavities and periodontal problems.

Causes of Periodontal Disease
There are many factors that can lead to periodontal disease, which can be broadly categorized as follows:
1. Systemic Factors
Hormonal imbalances (e.g., pregnancy), nutritional deficiencies (e.g., vitamin deficiencies), metabolic disorders (e.g., diabetes), blood disorders (e.g., leukocytosis), medication effects, genetic predisposition, and psychological or emotional stress can all affect the periodontal tissues and contribute to the development of periodontal disease.2. Local Irritation Factors
Poor oral hygiene can lead to accumulation of food debris, dental plaque, tartar, staining, and other irritants. Improper dental treatments, such as poorly shaped fillings or restorations, can directly irritate periodontal tissues, create hard-to-clean areas, trap food debris, and promote bacterial growth, all of which may cause periodontal problems.3. Local Functional Factors
-
Mouth breathing can dry out the gums, leading to tissue damage.
-
Habitual tongue thrusting can loosen periodontal tissues.
-
Teeth grinding (bruxism) places excessive load on the periodontium.
-
Malocclusion or misaligned teeth can cause bite-related trauma.
-
Improperly shaped restorations, incorrect occlusal height, or poor contacts with adjacent teeth can injure the periodontal tissues.
Symptoms such as bad breath, red or bleeding gums, recurrent abscesses, discomfort or weakness when biting, sensitivity to temperature changes, and loose teeth are all indicators of periodontal disease.
