This book describes major sources of traumatic and idiopathic adult chronic pain and provides an outline for successful treatment and relief of chronic pain symptoms - no matter their duration or severity. The treatments are focused on restoring comfortable and healthy jaw functioning patterns. Dr. Cameron describes the methods he used to successfully treat his patients over the past forty years through their stories. These stories are vastly different but have an underlying level of simplicity and sameness to them. After treating thousands of pain patients, patterns have emerged. The grouping of symptoms became similar, the diagnosis straight forward, course of treatment standardized and the outcomes, generally, predictable. Many of the standard dental thoughts on chronic pain are brought into question. Based on his work, Dr. Cameron proposes and describes a simple premise which leads to an elegant theory - namely - 'The Relatively Simple Theory of Jaw Function'. 'The Relatively Simple Theory of Jaw Function' places the general dentist, with his basic procedures, at the nexus of the treatment of chronic pain and dysfunction symptoms. From the stories in this book, the readers will see that the dentist has a significant influence on the comfortable function of the muscles and joints of the head and neck and, sometimes, throughout the body as well.
