Patient Safety
From this, we can see dental x-rays rank as the lowest exposures a patient might receive as part of their medical treatment.

Incidental Notes:

Gonadal protection may be of limited benefit to dental patients, but it may provide psychological comfort. Refer to your department policy to determine how you wish to address patient shielding issues.

As with all x-ray procedures, irradiation of pregnant patients must be done only when it is in the interests of maintaining maternal health.
