It’s necessary to balance the benefits of getting the information we need with minimizing any potential risks from radiation exposure. Dental X-rays are usually super safe, especially with modern equipment that keeps radiation levels low.

How many dental X-rays are safe depends on your age, dental health, and why you need the X-rays in the first place. Usually, for adults with good oral health, X-rays every 24-36 months are considered safe.

Can Too Many Dental X-rays Be Harmful?

Repeated radiation exposure is prone to causing cancer in the head and neck region, especially the thyroid gland. The level of radiation from dental X-rays is relatively low, and the risk of harm is considered minimal when X-rays are used correctly. To mitigate potential risks, dentists typically use lead aprons and thyroid collars to shield other body parts from radiation.

They also adhere to the principle of ALARA (As Low as Reasonably Achievable), meaning they use the lowest possible radiation dose necessary to obtain the required diagnostic information.

How Often Is It Safe to Get Dental X-rays?

The safety of the number of dental X-rays varies with your dental health. Individuals with healthy gums and teeth can take them once every 6-18 months. But if you have dental issues, like gum disease or dental decay, your dentist will need frequent dental X-rays to monitor it.

How Much Radiation Is Safe?

For dental X-rays, the radiation dose is relatively low compared to other medical imaging procedures. The effective dose from a dental X-ray is usually measured in millisieverts (mSv), with a single dental X-ray with a tiny dose, often less than 0.01 mSv. In perspective, the average annual background radiation exposure from natural sources in the United States is about 3 mSv.

In short, the risks associated with dental X-rays are considered minimal when performed according to recommended guidelines. However, it’s necessary to limit radiation exposure whenever possible, especially for vulnerable populations such as children and pregnant women.

Which Conditions Need Dental X-rays?

Dental X-rays are a modern tool for diagnosing numerous dental conditions that are impossible to spot with the naked eye. Following are some situations where dental X-rays are a dire need:

  • Detecting Tooth Decay: X-rays can reveal cavities between teeth or beneath existing fillings. These cannot be visible during a visual examination.
  • Assessing Gum Disease: X-rays help dentists see the extent of gum disease. As they show bone loss around teeth.
  • Monitoring Tooth Development: X-rays are used to monitor the development of permanent teeth in children and adolescents.
  • Assessing Tooth and Jaw Position: They can determine the position of impacted teeth, evaluate jaw alignment, and assist in planning orthodontic treatment.
  • Diagnosing Infections: X-rays can detect abscesses, cysts, or other infections in the jawbone or around teeth.
  • Planning Dental Procedures: X-rays provide valuable information for planning procedures such as tooth extractions, dental implants, or root canal therapy.
  • Evaluating Trauma: X-rays assess dental injuries resulting from trauma or accidents, such as fractures or dislocations.
  • Checking for Tumors: X-rays can help identify tumors or abnormalities in the jawbone or surrounding structures.

Final Verdict

Nobody can deny that radiation is harmful. You can’t completely avoid them, but consult a dentist for “How many dental x-rays are safe?” Most dental practices use the right frequency of radiation during dental X-rays to keep you safe.
