Dr. Gelb and his staff are amazingly professional and compassionate. I had an extreme case of TMJ, pain daily, unable to even yawl naturally, and at times, I could barely open my mouth. Within three months of wearing the appliances, (I had my doubts that they would help), I am basically pain free and it is a delight to be able to yawl, eat a salad, and be pain free. I am still wearing my day appliance for activities that are stressful and I wear my night guard every night. Three weeks of feeling great.
