According to Dr. Iwona, dental acupuncture is listed as the proven successful treatment for pain in dentistry. This modality can be used for acute or chronic dental pain, dental anxiety, nausea or gag reflex, and dry mouth. She mainly uses dental acupuncture for myofascial pain and any pain in the facial region.

Helping to alleviate patients’ pain is of paramount importance to Dr. Iwona. That’s why she participated in the Orofacial Pain Shadowing Program through the University of Kentucky College of Dentistry Continuing Education in Lexington. She earned a Certificate of Completion.

Dr. Iwona participated in seminars, case presentations, literature reviews and patient care activities totaling 40 hours. “I wanted to take part in the program to gain more experience and knowledge in how to diagnose and treat patients in pain.”

The Orofacial Pain Clinic was established in the 70s and was the first in the United States to treat facial pain patients. Its clinical director Dr. Jeffrey Okeson is a pioneer and world leader in the facial pain/TMD field.

Dr. Iwona chose to earn her certificate from the University of Kentucky as it has an excellent reputation. The institution is recognized as being a distinguished research and facial pain university. The biopsy samples that we take at our practice are sent to their oral path lab.
