You should see your obstetrician and advise him or her of the incident. They may want to do additional testing.
I would recommend you contact your obstetrician to further discuss this with him or her. So the answer again is unlikely. I hope this was helpful.

You should be fine.
Good luck with your pregnancy!
Most dentist will place an abdominal shield on patients regardless.
Nevertheless, if it was not placed on your stomach the xray beam is focused
to the head and teeth, well above the reproductive organs. The likelihood
of causing a miscarriage or fetal effects are extremely remote. You should
have noting to be concern about your dental xray and pregnancy.
