During pregnancy, hormonal changes, especially higher levels of estrogen and progesterone, influence how gingival connective tissue behaves. These hormones alter the activity of gingival fibroblasts and immune cells, shifting the balance of how the extracellular matrix is produced and broken down. A key part of this shift is a decrease in collagenase activity, which means less breakdown of collagen in the gingiva. This change in connective tissue turnover interacts with the heightened inflammatory response to dental plaque, contributing to common oral health changes like gingival swelling, increased bleeding, and gingivitis seen in pregnancy. Enamel mineralization is a developmental process set before birth, so pregnancy hormones don’t dynamically change enamel mineralization. Salivary flow can be affected by various factors, but it isn’t the central mechanism behind the pregnancy-associated gingival changes. Dentin sclerotization is an aging-related process and isn’t a feature driven by pregnancy hormones.
