Oakville dentist | Dr. Agatha Bis

Oakville Dentist, Dr. Agatha Bis, DDS received her Doctor of Dental Surgery degree from University of Western Ontario in 1996. With over 25 years of clinical experience creating beautiful and healthy smiles, Dr. Bis offers a unique approach to dentistry, blending modern dental practices with the use of digital technology to optimize health outcomes.
With thousands of hours in post-graduate training, her unique focus and expertise in treating TMD and providing options in restorative dentistry, along with digital technology has led to helping numerous patients resolve chronic and debilitating dental challenges.

Dr. Agatha Bis has spent nearly 30 years treating complex cases in private practice with a clinical focus on TMJ disorders, occlusion, restorative dentistry, and the systems that make treatment more predictable. She is also the founder of TMJ Whisperer Academy, an educational platform built for dentists who want to understand cases more clearly, diagnose with more confidence, and practice with more control.

Her approach is direct, structured, and clinically grounded. She challenges oversimplified thinking, emphasizes diagnosis before treatment, and teaches dentists to look beyond technique alone. The objective is not to impress with complexity. It is to help dentists see more clearly what is happening in front of them and know what to do next.

She speaks to a problem many dentists feel but rarely say out loud: the discomfort of looking at a case that should make sense and not fully understanding why it is failing. That is why TMJ Whisperer Academy is not simply positioned as continuing education. It is positioned as a place where dentists develop the framework that makes difficult cases more understandable, more predictable, and more satisfying to treat.

"Dr Bis is amazing! Her work is excellent, as is her patient communication. I’ve had some complicated procedures and she has given me great results, and a great patient experience. 5 stars!"
