When we use professional PBM units, we’re basically using specific light wavelengths to tell the cells in the dental tissue to stop stressing out and start repairing themselves. It’s great tech, but here’s the real challenge: how do you actually know it’s working? That’s where infrared thermography comes in. We use it as our eyes. Finding the “Hot Spots” Inflammation is noisy. When gums or ligaments are irritated, blood rushes to the area, which makes it warmer. An infrared sensor picks that up instantly. Instead of guessing where the problem is most acute, we map the temperature. By comparing the “hot” inflamed spot to the healthy tissue around it, we get a clear starting point. No more guessing. No more “I think this area looks a bit red.” We have the numbers. Did it actually work? The whole point of PBM is to calm that inflammatory response down. So, after a session, we scan again. If the surface temperature drops, we know the inflammation is easing and the blood flow is stabilizing. It’s a relief to see that shift on the screen. But if the map doesn’t change? Then we know the dosage is off or the light isn’t hitting deep enough. We can pivot right then and there. The tricky part It’s not perfect. These sensors are incredibly sensitive. A draft from the AC or even the patient’s own breath can mess with the readings. If the room temperature is swinging all over the place, your data will drift. You can’t just take one quick photo and call it a day; you need a stable average to get the truth. At the end of the day, the sensors aren’t the treatment—they’re the feedback. It takes the conversation away from “the patient says they feel better” and turns it into a measurable temperature drop. It lets us tweak the intensity on the fly, making the whole process feel a lot more precise.
