Most patients that are referred to my office have already received some form of treatment as the cause of their problems have not been corrected.  Over the last 30+ years I have developed, tested, utilized and have patented many of the methods you will find on this website.  These were developed because "conventional" methods did not prove sufficient to meet the patient's needs. 

Temporomandibular joint dysfunctions involve much more than just the jaw joints.  Headaches, neck pain, upper back pain, earaches, facial pain and tooth pain are just a few of patient's complaints.  It has taken years to develop examination and diagnostic methods and to incorporate them into a multi-professional treatment regimen that we provide.   

Bacteria living in the mouth live in biofilms that are not easily treated by brushing and flossing.  The Perio Protect Method has been shown to manage and control the bacteria associated with periodontal (gum) disease, decay and which have also been associated with multiple other disease such as; cardiovascular disease, Type II diabetes, pregnancy complications, Alzheimer's disease, arthiritic joint changes and other inflammatory problems.  
Philosophy of Practice
Successful recognition and interception can help prevent further degenerative changes and tissue damage.  It is our personal and professional goal to assist our patients in any means possible to obtain optimal health, healing and recovery using the treatment methods which have proven most effective and proficient that optimize long term stability at reasonable costs.
