1. Pre-pregnancy (the first three months of pregnancy): This period is a critical period for the development and formation of embryonic organs. Brain nerve, cardiovascular system, head and face, oral teeth, limbs and other organs are all formed at this stage, so they are most vulnerable to external influences. Improper use of drugs or high-dose X-ray irradiation can lead to abortion or fetal malformation. If pregnant women experience dental pain and anxiety during this period, it may have adverse effects on both the fetus and pregnant women, so doctors do not recommend dental treatment during this period unless it is an emergency.
2. The second trimester of pregnancy (fourth to sixth month): If teeth must be treated, this period is a more appropriate and safe treatment opportunity. It is recommended to do only temporary treatment, such as dental caries filling. If tooth extraction is needed, temporary dentures can be installed for beauty.
3. Late pregnancy (third trimester): Pregnant women in this period are not suitable for long-term dental treatment. First, the sensitive uterus is prone to premature contraction due to external stimuli; Furthermore, when the patient is in prone position during treatment, the weight of the fetus will compress the inferior vena cava, reduce blood reflux, cause postural hypotension, and at the same time reduce cardiac output, resulting in hypoxia in mental work, which may lead to syncope. It is recommended that pregnant women take the left lateral position to reduce weight oppression or occasionally change their posture.
Matters needing attention in dental treatment of pregnant women
1. drugs: in the treatment of dental diseases, local anesthetics are mostly used to relax patients. Pregnant women should avoid deep anesthesia. Other drugs, such as painkillers, sedatives and antibiotics (cyclosporine can cause fetal malformation during pregnancy), although most dental drugs are amber, they should be used with caution under the guidance of doctors.
2.x-ray irradiation: The dose of any dental radiation examination is very small, and it is far from the lower abdomen, so it should be within the safe range, but pregnant women should try to avoid it. However, if pregnant women need X-rays for emergency treatment, they must wear protective lead clothes and cover their lower abdomen. Pregnant dentists and assistants should also pay attention to their own protective measures. Women who have experienced abortion or premature delivery, are ready to get pregnant or are likely to get pregnant, should first let the doctor know about your situation so as to consider whether to modify the treatment plan or do preventive treatment first.
