Can pregnancy cause mouth ulcers?

During pregnancy, women may develop mouth ulcers. This is primarily due to significant hormonal changes following pregnancy, which may affect the metabolism of oral mucosa, leading to inflammatory reactions and the formation of ulcers. Additionally, during pregnancy, the fetus's increased nutritional demands may lead to nutritional imbalances if the mother's nutrient intake is insufficient, causing deficiencies in various vitamins, minerals, and trace elements, which can trigger mouth ulcers. To prevent mouth ulcers during pregnancy, pregnant women should maintain a pleasant mood, supplement nutrients appropriately, ensure a balanced diet, and maintain good oral hygiene. If mouth ulcers have already developed, some natural remedies such as honey rinses or honey application may be considered to relieve symptoms. Moreover, if the ulcers are severe or do not heal promptly, timely medical consultation is recommended, and treatment should follow the doctor's advice.
