Fluctuations in hormone levels can have a surprising impact on dental alignment, even though most people associate orthodontic issues with genetics or poor oral habits. During critical phases like adolescence, gestation, and perimenopause, the body experiences significant shifts in hormone levels that can affect the gums, bone structure, and the ligaments holding teeth in place. These changes can lead to gradual or perceptible changes in tooth placement.

During the teen years, increased levels of estrogen and progesterone can cause the gums to become more sensitive and reactive to plaque. This heightened sensitivity can lead to gingivitis and tissue enlargement, which may disrupt the natural anchoring of dentition. Over time, this can contribute to minor tooth movement, especially in individuals who already have a genetic tendency for tight or gapped teeth.

Pregnancy is another period where hormonal fluctuations play a role. The rise in progesterone and estrogen not only affects gum health but can also cause the supporting tissues and alveolar bone to relax. This natural process helps the body prepare for childbirth, but can also trigger subtle tooth migration. Many women experience perceived mobility in their dentition during pregnancy. In most cases, these changes are temporary and resolve after delivery, but in the absence of diligent hygiene they can lead to lasting alignment issues.

During the post-reproductive phase, when circulating estrogen diminishes, the periodontal deterioration and osteoporosis accelerate. Weakened maxillary and mandibular structure can compromise the support for teeth, 東京 部分矯正 causing them to drift outward or become more spaced apart. This is most frequently observed in the anterior region and may be confused with post-braces recurrence.

Crucially, hormones are seldom the primary cause of severe malocclusion, but they can act as accelerants. If someone has a past corrective dental intervention, hormonal changes can undermine retention efforts. flossing, and nightly retainer wear during times of physiological flux can help maintain alignment.

Clinicians must account for hormonal influences when evaluating dental changes. For women experiencing pregnancy or menopause, more frequent evaluations are recommended. Understanding this relationship empowers individuals to take proactive steps to protect their dental health during life stages that might otherwise be overlooked as unrelated to oral structure.
