Root Canal- 3rd Trimester?

Natasia

Has anyone had a root canal in their 3rd trimester? Is it safe? Was baby ok? I am just worried about the X-ray and anesthetic they use. I have a tooth that is acting up again and the dentist told me next time it happens I will need a root canal. I am 30 weeks pregnant and not sure if I should get it done or tough it out till baby is born...
