Dental x-rays are a routine part of oral care, yet many patients express concern or anxiety about the risks of these procedures. Let us clarify common myths and address the most common concerns with facts and expert advice.
Myth 1: Dental X-Rays Emit Dangerous Amounts of Radiation
In reality, the dose from a standard dental x-ray is extremely low, about 0.005 millisieverts per image. For comparison, the average person who receives a chest x-ray at the hospital can deliver up to 1,000 times more radiation than a dental x-ray. Advances in imaging have reduced exposure further, making dental radiology one of the safest diagnostic tools available. Digital radiology, when paired with tools like our Tarsier X, reduces the risk even further.

Myth 2: Dental X-Rays Cause Cancer
The risk of developing cancer from dental x-rays is negligible. Modern dental x-rays use minimal radiation, and strict guidelines ensure they are only taken when necessary. The benefits of early detection, such as catching cavities, infections, or bone loss, far outweigh the minimal risks. Studies have not found any causal link between dental x-rays and cancer at the doses used in dental offices.
Myth 3: X-Rays Are Only Needed If There’s a Problem
Some patients believe X-rays are unnecessary unless they have symptoms. However, many dental issues like cavities between teeth, bone loss, or impacted teeth are invisible to the naked eye and cause no pain until they are advanced. Regular X-rays help dentists detect problems early, preventing more complex and costly treatments down the road.
Myth 4: Dental X-Rays Are Unsafe for Children or Pregnant Women
Dental x-rays are safe for children and pregnant women as well. Dentists try to minimize doses and subsequent exposure by using protective measures like lead aprons and thyroid collars. It is important to notify your dentist when you’re pregnant so that extended measures can be taken for your safety.

Myth | Fact |
X-rays emit dangerous radiation | Modern dental x-rays use extremely low, safe doses of radiation |
X-rays cause cancer | No evidence links dental x-rays to cancer at standard doses |
Only needed if you have symptoms | X-rays detect hidden problems before symptoms arise |
Unsafe for kids or pregnant women | Safe when used appropriately, with added protections |
Bottom line
Dental x-rays are a safe, essential part of preventive dental care. If you have concerns, talk to your dentist. They’re committed to your safety and will only recommend X-rays when truly necessary.
