As we age our teeth and overall health becomes more important. Our bodies are affected by illness, medication and the aging of cells. Getting dental x-rays (Radio-graph) can help dentists identify issues within the mouth. This includes hidden structures, bone loss and small root cavities.

Understanding how safe, necessary and useful x-rays are can help give confidence to seniors.

Why Do Seniors Need Radiography?

As we age, there are specific changes within the mouth. Seniors can often have hidden issues.

  • Hidden Cavities – As gums recede, the root of the tooth becomes exposed. Bacteria will attack this area quickly causing deep cavities.

  • Bone Loss – Periodontal disease causes the jawbone to slowly deteriorate. X-rays can show if there has been a change in the jaw bone height. This allows dentists to treat patients with periodontitis before teeth become loose.

  • Old Fillings/Bridges/Crowns – Over time fillings, bridges and crowns begin to wear away. X-rays can identify small leaks and cavities.

  • Dry Mouth – Many common medications cause dry mouth. Without enough saliva to protect the teeth, decay occurs very quickly between teeth.

  • Jawbone Issues – X-rays can help identify hidden cysts within the jawbone, degeneration of the TMJ joint and unexpected changes.

Are Dental X-Rays Safe for Seniors?

Many older patients are concerned about the amount of radiation. However, digital x-rays are extremely safe to use. The benefits of x-rays outweigh any risks.

  • Very Low Radiation – Digital radiography uses very little radiation. Four bite-wing x-rays emit a small amount of radiation (0.005 millisieverts) which is the same as a few hours of natural radiation from space and the sun.

  • Lead Protection – Dentists will use lead aprons and thyroid collars to protect the vital organs.

  • Digital Sensors – Digital sensors use much less radiation than old films.

  • Following ALARA – The ALARA principal is followed (As Low As Reasonably Achievable). X-Rays will only be taken if necessary.

What Types Of X-Rays Will Seniors Get?

There are different types of x-rays dentists will take depending on the seniors needs.

  • Bite-Wings – These will show the upper and lower back teeth. Dentists can identify hidden cavities between tight teeth and check the upper jawbone.

  • Periapical – These will show the full tooth from the chewing part to the tip of the root. Dentists can identify deep cavities and nerve damage.

  • Panoramic – A panoramic x-ray uses a machine to rotate around the head to show a wide 2D x-ray of the whole mouth. This shows the joints, sinuses and any root fragments.

  • 3D CBCT – Cone Beam Computed Tomography provides detailed 3D images of the bone and nerves. This is vital to safely plan dental implants and complex operations.

What Considerations Should Seniors Know Before Having X-Rays?

Some patients may have health issues, mobility and cognitive issues that need to be considered.

  • Mobility – Modern dental practices will have accessible x-ray rooms. Wheelchair users can easily have panoramic or mobile x-rays.

  • Gag Reflex – Some seniors may have increased sensitivity or dry mouth causing them to gag when biting onto the sensor. Dentists can adjust the sensor or use comfortable external x-rays.

  • Joint Replacements – Seniors will be able to have x-rays safely. X-Rays will only affect a small area and will not cause any issues to joint replacements or pacemakers.

  • Cognitive – Seniors with dementia or Alzheimer’s will be treated gently by the dental team. Fast digital sensors will be used.

How Often Will Seniors Have X-Rays?

Dentists will not have a strict schedule for x-rays. They will tailor the amount of x-rays based on the seniors risk of cavities.

  • High Risk – Seniors with high risk of cavities ( lots of crowns, lots of dry mouth or active decay) will usually have bite-wings every 6-12 months.

  • Low Risk – Seniors with a healthy mouth and excellent hygiene will usually have bite wing x-rays every 18-36 months.

  • New Patients – If you are a new patient, the dentist will usually have a full mouth x-ray or panoramic x-ray.

What Are the Top Tips For Seniors Before Having X-Rays?

There are some tips you can do to make your x-ray as comfortable as possible.

  • Medical History – Tell your dental team about any medical conditions, recent operations and medications you are currently taking.

  • Dry Mouth – Tell your dentist if you suffer from dry mouth.

  • Lead Apron – Always ask for a lead apron and thyroid collar.

  • Discomfort – Tell the dental technician if the intraoral sensor is causing discomfort to your gums or causing you to gag.

  • Ask Why – Ask your dentist why they need to take any new x-rays.

What Are the Frequently Asked Questions About Dental X-Rays for Seniors?

Are Dental X-Rays Safe for Seniors With Medical Implants?

Yes! Dental x-rays are extremely safe for seniors with medical implants, joint replacements, heart stents or pacemakers. The x-rays will only use a targeted low dose of radiation and will not affect any metal joint replacements or heart devices.

How Can X-Rays Help Seniors With Missing Teeth?

X-rays will help identify the density and health of the jawbone. This will ensure your jawbone is healthy enough to have a partial denture, bridge or single tooth implant.

Will Medicare Cover the Cost of X-Rays?

Generally Original Medicare does not cover preventative dental, however many medicare advantage plans (Part C) will provide full dental coverage including 2 yearly diagnostic x-rays.

Can I Decline to Have X-Rays?

Yes! Every patient has the right to refuse any medical or dental treatment. However, if you refuse to have x-rays it will not be possible for the dentist to identify any hidden cavities, bone loss or deep infections.

Dental x-rays are a safe, low dose way to help keep seniors teeth healthy. X-rays can help identify hidden root cavities, check jawbone hold and check old dental work.
