Dental X-Rays: How They Work and How Safe They Really Are
Many patients at our DLF Phase 2, Gurugram clinic ask the same question before treatment: are dental X-rays really safe? It is a fair concern, especially for parents bringing in children or women who are pregnant. This article explains how dental X-rays work, how much radiation they involve, and how often they are actually needed.
How Dental X-Rays Work
A dental X-ray sends a small burst of radiation through your teeth and jaw onto a digital sensor or film. Teeth, bone, and fillings absorb the rays differently, creating an image that shows things not visible during a regular check-up, such as decay between teeth, bone loss, infections, impacted teeth, and problems below the gum line.
Most clinics, including Cliniva Dental Clinic, now use digital X-rays instead of traditional film. Digital systems produce an image on a screen within seconds and use significantly less radiation than older film-based methods.
How Much Radiation Is Involved
The radiation dose from dental X-rays is very small. To put it in perspective, here is a rough comparison of common radiation exposures.
| Source | Approximate Radiation Dose |
|---|---|
| One dental bitewing X-ray | Very low, comparable to a few hours of natural background radiation |
| Full mouth series (18 images) | Roughly equal to one to two days of natural background exposure |
| A round-trip flight (Delhi to Mumbai) | Similar order of magnitude to a few dental X-rays |
| Daily natural background radiation | We are exposed to this constantly from soil, air, and sunlight |
These figures are approximate and meant only to give a sense of scale. The actual dose depends on the type of X-ray, the equipment used, and how many images are taken. Modern digital sensors and lead aprons further reduce exposure during the procedure.
Are Dental X-Rays Safe for Pregnant Women?
Dental care, including necessary X-rays, is generally considered safe during pregnancy. A lead apron with a thyroid collar is used to shield the abdomen and neck area, and the radiation dose is very low. That said, our dentists at Cliniva Dental Clinic always ask about pregnancy beforehand and avoid X-rays unless they are genuinely necessary for diagnosis or urgent treatment. Routine, non-urgent X-rays are usually postponed until after delivery as a precaution.
Are Dental X-Rays Safe for Children?
Children's teeth and jaws are still developing, so X-rays can be important for spotting problems early, such as crowding, missing teeth, or hidden decay between baby teeth. Paediatric dental X-rays use a lower dose suited to a child's smaller size, and protective aprons are always used. Dentists generally take fewer and less frequent X-rays for children compared to adults, based on individual risk of cavities and development stage.
How Often Should You Get Dental X-Rays?
There is no single rule for everyone. Frequency depends on your oral health, age, and risk of dental problems. General guidance often followed by dentists includes the points below.
- New patients usually need a full set of X-rays to establish a baseline record of teeth and bone.
- Adults with good oral health and low cavity risk may only need bitewing X-rays every 12 to 24 months.
- Patients with a history of cavities, gum disease, or ongoing treatment may need X-rays every 6 to 12 months.
- Children may need X-rays more often during growth years to monitor developing teeth and jaws.
- Before procedures like root canals, extractions, or implants, a fresh X-ray is usually necessary regardless of when the last one was taken.
At Cliniva Dental Clinic, we do not take X-rays as a routine formality. Our dentists review your history and current condition each visit and recommend imaging only when it will genuinely help with diagnosis or treatment planning.
Simple Ways We Minimise Exposure
- Using digital sensors instead of traditional film wherever possible.
- Using lead aprons and thyroid collars during every X-ray.
- Taking only the number of images needed for your specific concern.
- Keeping a record of your previous X-rays to avoid unnecessary repeats.

Frequently asked questions
Can I get a dental X-ray if I am breastfeeding?
Yes. Dental X-ray radiation does not affect breast milk, so breastfeeding mothers can safely have X-rays taken when needed.
Do dental X-rays hurt?
No. The process is painless. You may feel mild pressure from the sensor or film placed in your mouth for a few seconds, but there is no pain involved.
How long does a dental X-ray take?
A single X-ray takes only a few seconds to capture. A full set for a new patient at Cliniva Dental Clinic usually takes about 10 to 15 minutes.
What if I recently had a medical X-ray or CT scan?
Mention this to your dentist. It is unlikely to cause any issue since dental X-ray doses are very small, but sharing your history helps us plan care sensibly.
