Extremely Caring

“Our family loves Dr. Feil and his team! They are extremely caring and create an experience far more impactful than just the process of getting braces. They took the time to help our children understand how to be successful through the process, took the time to get to know their personalities, and on top of that, they provide phenomenal dental work.”

- Jessie B.

Quality Care

"We loved how friendly, patient, and easy to work with all of the team was. We were always seen on time and out just as quickly but still received quality care. When we had an emergency case, they got us in and took care of it. We would highly recommend Feil Orthodontics to anyone in need of treatment!"

Your Bismarck Orthodontist

Meet Blake Feil, DDS, MS

Dr. Blake Feil is an orthodontist, entrepreneur, lifelong learner, and proud Bismarck resident.

He's been asking the community to “Smile with Feil” since opening Feil Orthodontics in 2009 and continues to serve the surrounding communities with locations in Bismarck, Mandan, and Beulah.

Why Orthodontics?

He began his entrepreneurial career in Mandan at age 11, catching and selling turtles, salamanders, frogs, fish, and snakes in a “pet shop” out of his garage.

He then co-owned his own vending machine company, which he ran throughout his years at Mandan High School.

After realizing that snakes and candy are best in small doses, he pursued a degree in orthodontics, allowing him to create smiles—something the world can always use more of.

Education & Experience

Dr. Feil is a strong advocate of lifelong learning and personal growth. He strongly believes that every person deserves to feel confident, capable, joyful, and worthy of a beautiful future. This drives him to help patients reach their personal goals daily as an orthodontist.

Dr. Feil takes pride in making sure his patients receive care consistent with the latest advancements in orthodontics.

Dr. Feil completed his undergraduate studies at the University of North Dakota, received his Doctor of Dental Surgery (DDS) degree at Creighton University in Nebraska, and earned his Master of Science (MS) and Orthodontic Certificate from the University of Colorado.

He has served as president of the longest-running dental education meeting in Colorado. He is currently a member of the American Association of Orthodontists and an active member of Spear Education, an innovative dental continuing education initiative.

Working for a Better World

Dr. Feil is proud to call North Dakota home and is passionate about seeing our state thrive.

He's been a strong supporter of the Bismarck/Mandan community, earning the Prudential Spirit of the Community award, and is proud to be an Eagle Scout from Mandan Troop 54.

Dr. Feil feels passionate about giving back to our community. He serves as a board member for the ND Department of Health Special Health Services and volunteers for the regional Cleft Lip Cleft Palate Clinic, which coordinates care for ND children born with craniofacial anomalies.

Outside of the Office

When he isn’t working with patients in his clinic, you’ll find Dr. Feil reading (a book or three a week), dreaming up new entrepreneurial ventures, planting (hundreds of trees a year) to support ND conservation efforts, hunting, hiking, traveling, and enjoying life with his wife, Tara, and their four wonderful kids.

Bismarck Braces

Traditional braces are one of the most efficient orthodontic tools we have. They're made out of metal or ceramic brackets attached to the teeth, then connected by wires and tiny rubber bands or elastics.

These brackets, wires, and bands work together to apply the gentle pressure that will gradually move the teeth into the positions we want them to be in if you have regular adjustments with Dr. Feil.

Braces are an excellent choice for correcting complex tooth issues. Braces may slightly reduce overall treatment time because they can sometimes work faster at aligning teeth and closing gaps than other treatments.

Braces don't need some of the more complex technology or expensive equipment that newer treatments can, making Bismarck braces a cost-effective orthodontic option.

Bismarck Clear Aligners

Clear aligners are incredibly popular with patients and orthodontists and is the top alternative to traditional braces. Instead of brackets and bands, A clear system uses a series of transluscent, removable aligners to straighten your teeth gradually.

Clear aligners are made of a comfortable plastic material and customized to fit snugly over your teeth.

To keep your teeth moving in the direction you want them to, you'll generally need to switch your invisible trays out every 1-2 weeks for the next in the series.

Clear aligner systems can only work if you follow the recommended guidelines exactly! You should wear aligners 20-22 hours per day throughout treatment. If patients neglect to wear the aligners as directed, it can impede the results and add time to the orthodontic process.

Clear aligner systems are at their most efficient when correcting many of the most common orthodontic issues. For some complex cases, clear aligners may not be a good option. A free consultation with Feil Orthodontics will allow us to determine your clear aligners eligibility.
