How can you safely have a root canal done in the beginning of the third trimester of pregnancy?

Yes: The alternative is to wait, but if the tooth gets infected, if you get swollen, and if you have severe pain, it will be more difficult to treat you rather than treat you now. Have your dentist talk to your obgyn.

Safe is relative -: Root canal treatment always caries some risk when provided to pregnant patients. However the relative risk is minimal in the second and third trimester. It would be a good idea if your endodontist discuses your treatment with your OB to customize the treatment to your special needs. Not treating the infection caries risks as well and must be weighed in the decision process. Best of luck.

Yes: If dental work is necessary, do it. Local anesthetic is safe. X-rays to the mouth will not cause harm to a baby, and your belly will be shielded, anyway. Sometimes a dentist or endodontist will ask for a note from your obstetrician.

Normally yes: The middle trimester is usually the best time for endodontic treatment. However, the beginning of the third trimester should not pose any problem. A better questiom would be, "what is the risk of waiting until after the birth?" if the answer involves continuing pain, infection or further loss of tooth structure then wisdom points toward completing the procedure.
