Are dental X-rays safe?

Modern digital dental X-rays use very low doses. Still, imaging should be justified by diagnostic need, especially for children and pregnant patients (with appropriate precautions).

Why do some offices X-ray every six months?

High-risk patients (recurrent decay, many restorations) may need closer monitoring. Low-risk adults often need bitewings less frequently. Ask what risk category you are in.

You can decline, but the dentist may limit treatment decisions or refuse certain procedures without diagnostic images. Discuss alternatives rather than silent refusal.

Should I transfer old X-rays to a new dentist?

Yes. Recent images can reduce duplicate exposure and help a new office understand your history faster.
