A dental x-ray is a useful diagnostic tool for detecting cavities in teeth, bone and gum disorders.

As for record keeping, a dentist may recommend x-rays to have a baseline to identify any changes later. Specific x-rays may be taken before treatment is done.

X-rays are safe but they need a low level of radiation exposure. Therefore , the risk of a harmful effect is low but real. X-ray equipment in Singapore are checked and require an annual licence to possess in order to ensure safety to the public.

Personal protection gear like a lead apron and thyroid shield are used to protect the patient.

For pregnant women, x-rays are usually avoided. But if the need is critical, use of leaded apron and/or thyroid shield will offer protection against radiation exposure.X-rays can be taken for breastfeeding mothers and women trying to get pregnant.
