Introduction

Generally, pregnancy itself does not directly cause tooth pain. However, physical changes and altered habits during pregnancy may indirectly lead to dental discomfort. If tooth pain occurs, prompt medical attention is recommended. Pregnant women experiencing tooth pain should seek timely care at the dental department of a正规 hospital, inform the doctor of their gestational age, and undergo safe diagnostic procedures and treatments under medical guidance, avoiding self-medication.

Generally, pregnancy itself does not directly cause toothache, but bodily changes and altered habits during pregnancy may indirectly lead to dental pain. If toothache occurs, prompt medical attention is recommended. The detailed explanation is as follows:

Pregnancy does not directly trigger tooth pain. However, increased levels of estrogen and progesterone during pregnancy can cause capillary expansion in the gums, making them more sensitive to irritation—minor plaque buildup may lead to redness, swelling, and pain in the gums. Some pregnant women consume more sugary or sticky foods and fail to clean their teeth promptly, accelerating plaque accumulation and leading to cavities, which may result in toothaches. Morning sickness and fatigue might reduce oral hygiene practices, allowing food debris to accumulate and worsen inflammation. Additionally, reduced saliva secretion weakens the natural buffering and protective effect on teeth, increasing tooth sensitivity and sharp pain. These physiological changes combined with altered behaviors contribute indirectly to dental discomfort.

If tooth pain occurs during pregnancy, it is important to seek timely care at the dental department of a reputable hospital. Inform the dentist about the gestational age and follow medical guidance for safe diagnostic procedures and treatments—avoid self-medicating. Maintain daily oral hygiene by brushing teeth twice a day with a soft-bristled toothbrush, rinsing with warm water after meals, limiting intake of sweets and sticky foods, and undergoing regular dental checkups to prevent oral health problems proactively.

Locally applied medications considered safe during pregnancy can usually be used under medical guidance, while drugs containing harmful ingredients or those not evaluated by a doctor are not recommended.

Can menstruation-inducing drugs cause miscarriage?

Whether a menstruation-inducing drug can cause miscarriage generally depends on whether the woman is pregnant and the type of medication used—it cannot be generalized. If the woman is not pregnant, using menstruation-inducing drugs as directed will not lead to miscarriage; however, if she is pregnant, certain types of such medications may trigger miscarriage. Therefore, when menstrual delay occurs, it is important first to undergo medical evaluation to confirm whether pregnancy is present, and then use menstruation-inducing drugs only under the guidance of a healthcare provider.

Will low progesterone in a subsequent pregnancy occur after a miscarriage due to low progesterone?

In general, having low progesterone levels during a miscarriage does not necessarily mean that progesterone will be low in the next pregnancy. Whether low progesterone occurs again depends on the physical condition during each pregnancy and the specific underlying causes, so it cannot be directly assumed. Women with a history of miscarriage due to low progesterone are advised to undergo relevant medical examinations before planning the next pregnancy, to identify the cause of the previous low progesterone and receive targeted treatment or调理 (regulation).

Can hepatitis B virus cause fetal malformations?

The hepatitis B virus itself usually does not directly cause fetal malformations; its primary risk is transmitting the virus to the fetus. To reduce the risk of mother-to-child transmission, pregnant women who are hepatitis B surface antigen positive should receive antiviral interventions under medical guidance, including appropriate use of antiviral medications during pregnancy and timely administration of hepatitis B immunoglobulin and the first dose of hepatitis B vaccine to the newborn after birth.
