Mouth breathing can have a profound impact on dental alignment, especially in growing individuals whose skeletal framework are still forming. When a person breathes through their mouth, the tongue does not rest in its natural position against the maxillary arch. This lack of normal tongue pressure can lead to a constricted maxilla and limited arch width for the teeth to grow straight. Over time, this may result in dental crowding.
In addition, mouth breathers often develop what is known as an anterior open bite, where the maxillary and mandibular incisors do not occlude during closure. This happens because the lingual posture tends to rest in the anterior gap instead of on the maxillary arch, exerting persistent thrust that pushes the teeth apart. The lower jaw may also develop in a retruded position instead of forward, contributing to a recessed chin and an distorted facial aesthetics.
Persistent oral respiration is often linked to nasal congestion caused by environmental sensitivities, tonsillar hypertrophy, or a deviated septum. These contributing factors need to be treated to avoid long-term orthodontic complications. Prompt treatment by a pediatric specialist can help reverse developing malocclusion before they become severe. In many cases, treating the root cause of the mouth breathing—such as reducing hypertrophic tissue or 墨田区 部分矯正 administering antihistamines—can allow the jaw and teeth to develop more normally.
Orthodontic treatment alone may not be enough if the dysfunctional pattern remains uncorrected. Without correcting the breathing pattern, teeth can shift back even after braces are removed. Myofunctional therapy, which restores proper neuromuscular function, is often integrated into comprehensive care to ensure stability.
Guardians should watch for red flags for airway issues in children, such as nocturnal snorting, dry lips, frequent throat infections, or a mouth-open posture. Intervening promptly can prevent not only dental misalignment but also enhance systemic wellness and sleep quality. Nasal respiration is evolutionarily designed and supports proper facial growth, so promoting nasal breathing is one of the most important steps in ensuring optimal oral health.
