Dental X-Rays: Safe, Smart & Essential for Oral Health | MI Dental Kitchener

Discover how modern digital X-rays help detect hidden dental issues with minimal radiation exposure. Learn about safety during pregnancy, after cancer treatment and why X-rays are key, even when there is no pain.

When it comes to your oral health, seeing is believing—but sometimes, what needs to be seen is hidden beneath the surface.

That’s where dental X-rays come in. Far from the outdated systems of the past, modern digital dental X-rays are faster, safer and incredibly precise. They help us uncover what the naked eye simply cannot see and they do so with minimal radiation exposure.

Are Dental X-Rays Safe?

Yes, absolutely! Modern dental X-rays are extremely low in radiation, especially with today’s digital imaging technology. In fact, the radiation dose from a set of dental X-rays is often lower than what you are exposed to during a short flight or from simply living your life over the course of a day. For example:

  • A set of 4 BiteWing X-rays = about 0.005 millisieverts (mSv)
  • A Panorex X-ray = around 0.01 mSv
  • Compare this to:
    • A cross-country flight = 0.03 mSv
    • Background radiation we receive daily = 0.01 mSv per day

So, yes, dental X-rays are safe and essential.

Why Do We Need X-Rays at All?

A visual exam gives us only a partial view. The spaces between teeth, under fillings and around roots are hidden from direct view. Dental X-rays help detect:

  • Cavities between teeth
  • Infections at the root tip
  • Bone loss due to gum disease
  • Jawbone conditions and cysts
  • Developing teeth in children
  • Position and health of wisdom teeth
  • Root length and shape before extractions or root canals
  • Bone quality and volume before placing dental implants

Without X-rays, much of modern dentistry would be guesswork and that is not good enough when it comes to your health.

Types of Dental X-Rays We Use

  • Bitewing X-Rays
    Taken once a year, these are the go-to images for detecting cavities between teeth, especially in those tight contact areas that toothbrushes and even floss sometimes misses.
  • Panoramic X-Ray (Panorex)
    Recommended every 3 years, this X-ray gives us a big-picture view of your entire mouth: upper and lower jaws, jaw joints (TMJ), sinuses and developing or impacted teeth, especially useful for assessing wisdom teeth and jawbone pathology.

Special Considerations

Pregnancy

We generally avoid X-rays during pregnancy, especially in the early months. However, in emergencies, they can be safely taken with proper lead apron shielding over the abdominal area. If you are pregnant and in pain or have an infection, we will take every precaution to ensure your safety while getting you the care you need.

After Radiation Therapy (Cancer Treatment)

If you have recently undergone radiation therapy, please let us know. We will:

  • Consult with your oncologist
  • Review your treatment details
  • Minimize radiation exposure
  • Proceed only when medically necessary, using the lowest effective dose and digital sensors that require significantly less exposure than traditional X-rays.

Children

X-rays are safe for children and in fact, they are essential for:

  • Monitoring jaw development
  • Ensuring permanent teeth are developing properly
  • Catching issues early before they become bigger problems

“But I Don’t Feel Any Pain—Why Do I Need an X-Ray?”

We hear this often and it is a great question. But here’s the thing: pain is a late-stage symptom in dental disease. Cavities, infections or bone loss can progress silently for years before you feel anything. By the time a tooth hurts, the damage may already have advanced. X-rays help us catch problems early, before they hurt and before they become more complicated and costly to fix. Absence of pain is not a good yardstick to ascertain the health of a tooth. 

When X-Rays Are Non-Negotiable

  • Before placing a filling – to assess the depth of the cavity
  • Before a tooth extraction – to see the root shape and angle
  • During a root canal – to monitor canal cleaning and length
  • For implants and dentures – to evaluate bone quality and structure

In short, X-rays are not optional in quality dental care, they are an integral diagnostic tool.

In Conclusion

Modern dental X-rays are safe, low-radiation and incredibly valuable in helping us detect issues early, plan treatment accurately and deliver care confidently. They are tailored to your individual needs and used only when necessary with your safety as our top priority.

If you have questions or concerns about dental X-rays, talk to us, we are here to help you make informed decisions for your health and peace of mind.
