I'll admit that when I first heard about using red and near-infrared light in connection with dental implant healing, I was skeptical. “Red light therapy” is one of those phrases that has become so common in consumer wellness that it's easy to dismiss it before looking at the biology behind it.
Then I started learning about photobiomodulation, or PBM. What caught my attention wasn't the device or the light itself, but what researchers are investigating at the cellular level.
