Is it safe to use surgical anesthesia for wisdom tooth extraction during pregnancy?


I am currently about 27 weeks pregnant and have a horizontally impacted wisdom tooth that is causing unbearable pain.
I hope to have it extracted, but after filling it, the pain persists.
The dentist advised me to consult first: is it safe to use "surgical anesthesia" during pregnancy? If it is, he will proceed with the extraction, as he is concerned that it may be less suitable to perform the wisdom tooth surgery later in the pregnancy.
I would greatly appreciate the pharmacist's guidance on this matter!

Hello: It is very important to be cautious about medications during pregnancy, which are classified into five categories: A, B, C, D, and X.
Medications classified as C, D, or X require special caution.
There are many types of anesthetics, especially those used during tooth extraction, but I am not aware of which anesthetic you are using.
The use of anesthetics can have different effects depending on the stage of pregnancy—early, mid, or late.
Some may pose risks during the late stages of pregnancy but not during the early stages.
Since you are in the mid-pregnancy stage, it is still advisable to be cautious with medication.
Wishing you safety and happiness.
Thank you for your guidance.

When it comes to dental procedures during pregnancy, particularly wisdom tooth extraction, there are several important factors to consider. As you are currently 27 weeks pregnant and experiencing significant pain from a wisdom tooth, it is understandable that you are seeking a solution.
Firstly, it is generally accepted that dental treatment, including the extraction of wisdom teeth, can be safely performed during pregnancy, especially during the second trimester (weeks 14 to 27). This period is often considered the safest time for dental procedures because the risk of miscarriage is lower, and the fetus is less vulnerable to potential complications that may arise from anesthesia or medications.
Regarding the use of anesthesia, local anesthesia is typically deemed safe for pregnant women. The most commonly used local anesthetics, such as lidocaine, have been studied and are classified as Category B by the FDA, indicating that they are generally considered safe for use during pregnancy. These anesthetics work by blocking nerve signals in the area where they are administered, allowing for pain-free procedures without affecting the overall consciousness of the patient.
However, it is crucial to communicate openly with your dentist about your pregnancy and any concerns you may have. Your dentist will likely take extra precautions, such as using the lowest effective dose of anesthesia and monitoring your condition throughout the procedure. Additionally, they may want to consult with your obstetrician to ensure that all aspects of your health and the health of your baby are considered before proceeding with the extraction.

It is also important to address the pain you are experiencing. Dental pain can lead to stress and discomfort, which may have indirect effects on your pregnancy, such as increased uterine contractions or anxiety. Therefore, managing this pain is essential not only for your comfort but also for your overall well-being during pregnancy.

If you are considering delaying the extraction until later in your pregnancy, it is important to weigh the risks. As you approach the third trimester, certain positions during dental procedures may become uncomfortable, and the risk of complications may increase. Therefore, if your dentist recommends extraction now, it may be in your best interest to proceed.

In summary, wisdom tooth extraction during pregnancy, particularly in the second trimester, is generally safe when performed with appropriate precautions. Local anesthesia can be used effectively without significant risk to the fetus. However, it is essential to have a thorough discussion with both your dentist and obstetrician to ensure that all safety measures are in place and that you are comfortable with the decision. Your health and the health of your baby are paramount, and addressing the dental issue promptly can help alleviate pain and stress during this important time in your life.
