Overjet refers to the horizontal distance between the upper and lower front teeth when the jaws are closed — a common orthodontic condition where the front upper teeth extend too far beyond the lower ones. While a slight gap of overjet is normal and healthy, an excessive overjet can cause functional problems, make the front teeth more vulnerable, make eating uncomfortable, and even undermine self-confidence due to appearance-related anxiety.

Overjet can stem from a variety of causes. Hereditary factors are often key, meaning the skeletal framework of the face can be passed down through families. Additional triggers involve prolonged thumb sucking, extended bottle or pacifier dependency, which can push the top teeth outward while retracting the mandibular dentition. Mouth breathing due to nasal congestion can also alter facial growth patterns. In certain cases, tooth loss in the lower arch or a retrognathic mandible may exacerbate or cause the condition.

Treatment strategies for overjet depends on the severity of the case and the developmental stage. For young patients, early intervention is typically most effective. Braces and clear aligners are standard tools to align the dental arches. When dysfunctional jaw development is involved, functional appliances such as facemasks or palatal expanders may be recommended to encourage mandibular advancement or restrict excessive upper jaw growth.

For adults with severe overjet, non-surgical correction may be inadequate to achieve optimal results. In such cases, maxillomandibular osteotomy may be necessary to properly realign the jaws. This procedure is used in tandem with orthodontic treatment to achieve ideal occlusion.

The length of treatment varies widely, depending on the complexity of the malocclusion. Slight protrusion can often be resolved in 12–18 months, while complex cases may require two years or more. Frequent orthodontist visits are vital to track progress and prevent setbacks.

If you or your child exhibits signs of overjet, it is highly advisable to seek expert evaluation. A preliminary screening, ideally around the age of 7, allows the orthodontist to detect potential issues early and prevent more serious complications. Treatment doesn’t just enhance appearance — it also improves functional stability by optimizing bite mechanics.

Maintaining excellent oral hygiene during treatment is vital. Orthodontic devices can trap food and plaque, so consistent brushing and flossing, along with professional prophylaxis, are critical for avoiding cavities and periodontal issues. Once appliances are removed, following retainer protocols is mandatory to prevent relapse.

Knowing the options for overjet correction empowers individuals and caregivers to make confident, informed decisions. With expert-guided care, nearly all patients can be successfully corrected, resulting in better chewing ability, increased ease of use, 東京 前歯矯正 and long-term emotional well-being.
