Can my pregnant sister get a radiograph taken for her tooth?

Q: My sister is pregnant and she needs a root canal filling for her molar tooth. Can she have a radiograph taken for the tooth by wearing a lead apron? Please explain.

A:Yes, she can have it done after protection with lead apron. Alternatively, along with lead apron protection, she can get it radiographed with digital radiography which requires less radiation andstill safer(RVG).
