If you've had chronic sinus problems and every ENT tells you nothing is wrong -- watch this. The maxillary sinus sits directly above the upper back teeth. In many people, the roots of those teeth actually extend into the sinus floor. Now imagine one of those teeth is root canal treated. Chronically infected. Silently inflamed. The sinus membrane directly above it stays permanently irritated. Blocked nose. Pressure. Recurring inflammation. No obvious cause on a standard scan. So what happens? The ENT does what ENTs are trained to do -- they go in from the side, open the sinus, and clear the inflammation. More invasive. Temporary fix. Because the source is still there. In Biodentistry 3.0, we ask a different question first: what is sitting below that sinus? Remove the infected tooth. Clean the dental focus. Address the actual source. And in most cases -- the sinus clears on its own. The membrane reduces. The inflammation resolves. Without touching the sinus at all. My honest estimate: 80% of chronic, recurring sinus inflammation has a dental origin that nobody is looking for. Not because it's hidden. Because no one is asking the dentist and the ENT to talk to each other. Cheers, Dr. Dome - @drdomeofficial
