Koala Center for Sleep & TMJ Disorders Wausau Welcome to the Koala Center for Sleep & TMJ Disorders of Wausau Wisconsin! Dr. Rod Willey treats snoring, sleep apnea and TMJ pain.

Our provider Dr. Rodney Willey DDS, D.ACSDD, D.ASBA is a Diplomate with the Academy of Clinical Sleep Disorder Disciplines and American Sleep and Breathing Academy. His career path has taken him from general dentistry, to the study of functional orthodontics at the U.S. Dental institute, to Neuromuscular Occlusion from the prestigious Las Vegas Institute for Advanced Sleep Studies, to the treatment of Obstructive Sleep Apnea with Oral Appliance Therapy. He is the founder and developer of the Koala Center for Sleep & TMJ Disorders franchise. Brenda Mittelsteadt has been a Board Certified Family Nurse Practitioner for over 23 years. Her background is diversified, as she has specialized in emergency medicine, acute/urgent care, general and vascular surgery (specializing in bariatric and varicose veins), occupational health, and family practice. She completed her Bachelor and Master of Science degrees at the University of Wisconsin, Eau Claire. She holds national board certification with the American Nurses Credentialing Center (ANCC) and also holds a Driver of Transportation (DOT) certification. She delivers personalized, high-quality patient care with compassion and an emphasis on educating the patient while building a therapeutic relationship built on trust and evidence-based practice. Her philosophy on care is patient-centered, using a team approach, and she thrives on helping people navigate through their health concerns towards health promotion and maintenance. She believes her success as a nurse practitioner requires her to have continual dedication to help impact and improve the lives of her patients through a lifelong pursuit of knowledge and personal growth. As she has experienced the impact of obstructive sleep apnea (OSA) and temporomandibular joint disorders (TMD) in patients through primary care, she has recently switched her interest to focusing on helping these patients. In her spare time, she enjoys spending time with her family and friends, vacationing, being outdoors, and watching her son play hockey.

Relax Your Jaw: Check Throughout the Day That Your Teeth Are Apart and Muscles Are Loose. (Koala Center for Sleep Disorders)

Practice "Active relaxation" throughout the day by checking that your teeth are slightly apart and your facial muscles are loose. This simple habit helps reduce the cumulative muscle tension that often leads to nighttime clenching and morning jaw pain.

Why Do I Feel “Locking” or “Popping” in My Jaw First Thing in the Morning? (Koala Center for Sleep Disorders)

Popping and clicking are often caused by the cartilage disc inside your jaw joint slipping out of place due to nighttime muscle tension or clenching. If left untreated, this displacement can progress to "locking," where the jaw becomes stuck or has a significantly limited range of motion.

Is your jaw trying to tell you something? Call Koala® Center For Sleep & TMJ Disorders or visit us online to book a professional evaluation.

Alcohol Helps You Sleep Better If You Have Apnea. (Koala Center for Sleep Disorders)

While alcohol may help you fall asleep faster, it actually acts as a muscle relaxant that causes the throat muscles to collapse more easily. This significantly worsens airway obstructions and leads to more frequent breathing interruptions throughout the night.

How Does an Imbalanced Bite Contribute to Facial Pain and Headaches? (Koala Center for Sleep Disorders)

When your teeth don't align properly, your jaw muscles must constantly overcompensate to chew and swallow, leading to muscle fatigue and inflammation. This strain often radiates outward, causing chronic facial pain and morning headaches that are frequently mistaken for migraines.

Don't let an imbalanced bite control your day; reach out to our team at Koala® Center For Sleep & TMJ Disorders for lasting relief.

Why “Morning Headaches” Are Often a Jaw or Airway Signal? (Koala Center For Sleep & TMJ Disorders)

Do you Wake up with a dull, throbbing headache that fades as the day goes on? At Koala® Center For Sleep & TMJ Disorders, we find that morning headaches are rarely "just a headache." They are often caused by the jaw muscles working overtime to keep your airway open or by the strain of TMJ Disorder. By using a custom oral appliance to bring your jaw into a harmonious, relaxed position, we can help eliminate the root cause of the tension - so you can wake up pain-free and truly refreshed.

Fact: It is a systemic cardiovascular and metabolic health risk. Untreated sleep apnea puts immense strain on your entire body. It is closely linked to serious systemic issues like hypertension, cardiovascular disease, and type 2 diabetes, making it a medical priority rather than just a nighttime nuisance.

Why Is Snoring Often More Difficult to Diagnose in Women than in Men? (Koala Center For Sleep & TMJ Disorders)

Women frequently experience "atypical" symptoms such as insomnia, morning headaches, and exhaustion rather than just loud snoring. Because their symptoms don't always match the traditional "loud snorer" profile, their sleep disorders are often overlooked or misdiagnosed.
