Is it safe to have an X-ray during pregnancy?

hi. im a dentist. yup true the dental xray radiation is not harmful enough for the fetus as very very low radiation is used and only localized at jaw area. but usually we did xray for cases that really requiring or in need of the xray becoz still we want to minimize exposure as lowest as possible to the mother. but it is by far not harmful. if the cases really really need xray, some dentists usually just did it but not too frequent at a time. that's from my experience as a dentist. as for me i usually try to avoid taking the xray unless the case is really for emergency such as for acute minor oral surgery procedure.
