@drjoedamiani: 🦷 Got sensitive teeth? You’ve probably been told it comes from brushing too hard, acid reflux, or clenching… but that is not the whole story. There are 3 surprising causes no one really talks about, and the tricky part is they might not even be coming from your teeth. 1. Muscle spasms 💥 The two strongest chewing muscles, the masseter in your cheek and the temporalis at your temples, connect into the same nerve network that supplies your teeth. These are branches of the trigeminal nerve, specifically V2 and V3. When those muscles spasm or stay tight, they can irritate the nerve endings and the brain cannot tell if the pain is coming from the tooth or the muscle. That is why a perfectly healthy tooth can feel sore or sensitive. 2. TMJ issues 🦴 The jaw joint itself is supplied by the auriculotemporal nerve, which is another branch of the trigeminal nerve. If the joint becomes stiff, inflamed, or overloaded, it irritates that nerve and creates pain that feels like it is coming from the teeth. Many people feel a sharp zing or toothache that has nothing to do with enamel or cavities, but everything to do with the jaw joint. 3. Neck tension 💆‍♀️ The nerves from the upper neck, especially C2 and C3, plug into the same brainstem hub as the trigeminal nerve. This hub is called the trigeminal cervical complex, and it acts like a relay station for head, face, jaw, and tooth pain. When the neck nerves get irritated, the brain can misread the signal and make your teeth feel sensitive, even though there is nothing wrong with them at all. So if you keep trying dental fixes and nothing is working, it might not be your enamel. The real cause could be your muscles, your jaw joint, or your neck. #sensitiveTeeth #toothpain #tmjdisorder #jawpain #neckpainrelief
