(1) Hormone changes: During pregnancy, due to the increase of estrogen and progesterone in the body, the endocrine system has undergone great changes, which makes the capillaries of the gums dilate, bend and weaken their elasticity, leading to blood stasis and increased vascular wall permeability. Women during pregnancy are prone to gum bleeding, swelling, bad breath and gingivitis. Moreover, due to the changes of hormones during pregnancy, it will aggravate the original inflammation of gums and cause acute attacks.
(2) Deterioration of dental caries: For example, pulpitis or periapical periodontitis generally develops from dental caries.
(3) Eating habits: Pregnant women's food intake and frequency have increased significantly, and they prefer acidic and sweet foods, so they will hurt their teeth. In addition, some pregnant women often feel tired and inconvenient to move, which leads to an increase in the incidence of toothache.

(1) Inflammation of wisdom teeth: Wisdom teeth are more common in pregnant women aged 20-30. Inflammation of pregnant women's wisdom teeth can lead to toothache, and there will be symptoms such as swollen face and inability to open the mouth. When pregnant women have wisdom teeth, they can generally go to the hospital to wash their teeth locally, and cooperate with correct brushing methods and mouthwash to maintain oral hygiene. They can have their teeth extracted after delivery.
(2) Acute pulpitis: If pregnant women have a particularly severe toothache at night, the pain is a sense of jumping and burning, and the pain has always been rotten teeth, which may be acute pulpitis. Acute pulpitis needs root canal treatment and should be carried out according to the doctor's advice.
(3) Gingival pregnancy tumor: After some women are pregnant, a tumor-like thing will grow on the gingival papilla between the two teeth, some of which are particularly red, easy to bleed and soft; Some of them are almost the same color as normal gums, are not easy to bleed and are hard, but all of them have a tiny pedicle attached to the gums. The occurrence of this small tumor is related to pregnancy, which gradually increases with the development of pregnancy, but it is not infinite. When the diameter reaches about 1 cm, it will not increase any more. If this happens, there is a pregnancy tumor in the gums.
