I had the pleasure of seeing Dr. Sep and his lovely team for an assessment and treatment of TMJ pain and my experience was absolutely amazing from start to finish. The welcoming atmosphere made me feel comfortable right away and the examination was extremely thorough. Dr. Sep was incredibly polite, kind, and patient, he explained everything clearly. I felt genuinely cared for and highly recommend them to anyone looking for exceptional dental care.

My journey in improving my sleep apnea with the lovely team at Root Cause Dental Group took well over two years, but that is no fault of theirs. My body is extremely sensitive to sleep adjustments and they gave me time and grace to work through the changes. With their ongoing in-office treatment and follow-through, my severe sleep apnea is almost non-existent now. Thank you for always being kind, non-judgemental, and in support of making my sleep and quality of life better!

I came to this business because they were referred to me from my Specialist. They gave me a very thorough four hour consultation. I was very impressed with their equipment and assessment tools. They provided a splint for my low bite that was causing lots of pain and headaches for me and it has significantly improved my quality of life. I’m very happy with their service, they’re friendly and very professional. They gave me hope and today I can smile again without pain. Highly recommend them!

Highly recommend the team at Root Cause. Everyone is very knowledgeable and friendly. I see Amanda for my Invisalign and she is incredibly professional and kind. The care team worked with me to come up with an alternate treatment plan for TMJ when the first one wasn’t working. They were very flexible and care about patient outcomes. The front staff are friendly and the office is always clean and tidy. Highly recommended for specialized dental care.

My experience with Root Cause Dental Group has been amazing! I was having significant TMJ issues so I was referred to Dr.Sep by my dentist. Everyone at this location is so warm and welcoming and they know their stuff! The dental appliances that were customized for me have worked brilliantly and I barely have any issues with my TMJ anymore. The level of genuine care that you receive from this team is remarkable. Everyone here is invested in your success and well being. I highly recommend Dr. Sep and the team!!
