I would like a Dr. to tell me what is the best stage during pregnancy to get any type of dental care. Thanks

I am 13 weeks pregnant and have two molars that are bothering me, and i am afraid that i may have to have a root canal. I know that you have a limited selection of medications you can take for pain, but i know, that the infection in my molars will only go away if they treat it. How bad will the procedures affect me and the baby.

If you want a Dr. to tell you something, please don't ask these questions here, otherwise, here is something I found: Most obstetricians and dentists prefer that dental treatment take place during the second trimester, if possible. Many physicians and dentists agree that dental care during the first trimester should be kept to a minimum. The first trimester is the time when most of the fetal organs are developing. While dental treatment may not necessarily harm these organs, it is best to minimize any potential risk. During the second half of the third trimester, dental care should also be minimized. This is mostly due to the comfort of the expectant mother. When laying back in the dental chair during the late stages of pregnancy, the uterus can place pressure on the inferior vena cava (the main vein which returns blood to heart from the lower extremities). Not only is this uncomfortable, but it can also create a loss of consciousness.
