The End of the Dental Drill? How Red & Infrared Light Can Kill Pain, Speed Healing, and (Maybe) Regrow Teeth
The dental drill may be the most iconic sound in healthcare—but this deep dive argues it doesn’t have to be the future. Drawing from a 2026 review paper (“Photobiomodulation in Dentistry”) in the International Journal of Advanced Research, we break down how “cold” red and near-infrared light (PBM) can donate energy to oral tissue, boost ATP production via mitochondrial cytochrome-c oxidase, and trigger repair signaling—without heat, cutting, or drugs.
We explore why a temporary ROS spike can be helpful (hormesis), how PBM can reduce pain by calming nerve excitability and inflammation, and why…
