7 Signs Your Dental X-Ray Sensor Needs Repairs

Like any piece of equipment, dental X-ray sensors can wear down over time, leading to performance issues that disrupt your workflow. If you’ve ever wondered when a dental sensor needs repair, recognizing the early signs can help you avoid unexpected downtime and costly replacements. Here are seven signs that indicate your dental X-ray sensor may need repair.

How to Know When a Dental Sensor Needs Repair

1. Sensor Works Part-Time 

The most common issue with sensors needing repair is intermittent function. Sometimes it works, and sometimes it does not. For example, the device can still get good images, but it can’t get through an FMX without problems. Or it auto-triggers before being exposed to radiation.  

2. Poor Image Quality

Another common sign of sensor trouble is a decline in image quality. Because poor image quality can affect diagnostic accuracy, repairing this issue is crucial. Your sensor may have internal damage, faulty wiring, or another issue in need of repair if you notice any of these signs:

  • Blurry or distorted images
  • Unusual lines, artifacts, or dead pixels
  • Inconsistent brightness or contrast

3. Physical Damage

Physical damage can lead to performance issues and may cause the sensor to fail completely. Seek professional repairs immediately if you notice visible signs of damage, such as:

  • Cracks or dents on the sensor body
  • Frayed, bent, or exposed wiring
  • Loose or damaged sensor housings
  • Broken or bent USB connector

4. Overheating or Malfunctioning

Sensors that become unusually warm during use or behave erratically may have internal component issues. Ignoring the problem can lead to permanent sensor failure, so it’s best to schedule maintenance as soon as possible. Your sensor may need repairs if:

  • It shuts off unexpectedly
  • Error messages appear during use
  • You need to restart it frequently

5. Electrical Arcing

Sparks or unusual flickering within the sensor system can indicate serious electrical problems. Your sensor will need immediate repairs to prevent further damage. Signs of electrical arcing include:

  • Unusual flashes or sparks near the sensor connections
  • Burning smells or discoloration around the cables
  • Unstable image quality or sudden shutdowns

6. The Sensor Won’t Turn On

First, check the power connections and software settings. If the device still won’t turn on, you’ll need to call in a technician. Failure to start could be caused by:

  • A damaged power supply or faulty wiring
  • Internal circuit board failure
  • Software glitches 

7. Your Sensor Is Nearing the End of Its Lifespan

Newer dental X-ray sensors only last around eight years. However, older models last longer and are more repairable, making them worth the investment. 

Signs that your sensor may need repairs due to age include:

  • Slower performance or response times
  • Frequent glitches or connection issues
  • Incompatibility with software updates

We highly recommend Erik and DSRex.com!  They were helpful, kind, knowledgeable and very professional.  Not only did Erik get us the sensor we needed, he helped get our old one fixed so we could have a back up.  They went above and beyond any other company that we tried  to locate a sensor or fix our broken one! Great company and great customer service!

Over the past couple of years our office has sent in several Schick sensors and cables for repair. I have found Erik to be very upfront about what his team is able to do and whether or not the item is even worth repairing. DSRex is very diligent and will work hard to source items needed for the repair process. They communicate well throughout the process and are attentive to the customer’s timeline for repair.  

Being the owner of a busy dental practice I only trust Dental Sensor Repair Experts. Dental Sensor Repair Experts have quickly and effectively fixed my dental sensors on several occasions. Their customer service is top notch and their prices are very fair. Additionally, the turn around time has always been very fast allowing me to resume my normal radiology as quickly as possible.

I was referred to Dental Sensor Repair Experts a year ago when I had a few sensors quit on me. In a pinch, they repaired all of them quickly, and saved me thousands! It’s been a year now, and all my sensors are still working with no problems! Great company, great people!
