If your daughter has been somewhat behind the average for other physical developments, the fact she has no teeth yet may not be a major concern. Except for dental emergencies, I do not normally recommend x-rays for infants. This is because it's often difficult to get the child to cooperate.
Many dentists also like to be ultra cautious about exposing developing bone to x-rays.
It may be difficult to convince your infant daughter to cooperate with this procedure. One way to improve cooperation would be to have your daughter sit on your lap so you can hold her still. Both of you should wear the lead shields. Discuss this plan with your family dentist. You should not rely on this information as a substitute for personal medical attention, diagnosis or hands-on treatment.
