Many people fear dental X-rays because of “radiation” — but modern dental X-rays actually use extremely low radiation levels.
In fact, a full-mouth series of modern digital dental X-rays may expose you to less radiation than a short airplane flight. Modern digital systems also use up to 80% less radiation compared to older film-based X-rays, while helping dentists detect problems much earlier and more accurately.
Dentists also follow strict safety guidelines called the ALARA principle, which stands for “As Low As Reasonably Achievable.” This means X-rays are only taken when truly necessary and with the lowest radiation dose possible. Additional protective measures may include lead aprons, thyroid collars, digital sensors, and very fast exposure times.
For pregnant patients, dental X-rays are generally considered safe when needed and properly shielded, but it’s always important to let your dentist know if you are pregnant or think you may be.
The small amount of radiation from dental X-rays is usually far outweighed by the benefit of finding infections and disease early — before they become painful, dangerous, or expensive to treat.
