Bad breath during pregnancy may be caused by the following factors:
1. Elevated estrogen and progesterone levels during pregnancy lead to significant hormonal fluctuations, contributing to halitosis.
2. Poor oral hygiene—such as infrequent toothbrushing—during pregnancy.
3. Constipation, which commonly occurs during pregnancy and can also cause bad breath.
4. Changes in taste preferences during pregnancy, leading to increased consumption of pungent or spicy foods.
