I'm So Happy

“Absolutely the best Orthodontics hands down. Dr. Feil is amazing and it shows in his work and his relationship with his clients. I would never recommend anyone else.

Feel Like Their Family

“Our second child just got his braces on and we were worried how he would handle the process but the Feil Orthodontics team was so patient and accommodating. Everyone there is great and makes our entire family feel like their family! We are very happy with the care both our children have received.”

Your Mandan 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.

Mandan Braces

Traditional braces are one of the most efficient orthodontic tools we have at Feil Orthodontics. They're made out of metal or ceramic brackets that are 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. Because they can sometimes work faster at aligning teeth and closing gaps than other treatments might, overall treatment time may be slightly reduced.

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

Mandan Invisalign

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

Invisalign aligners are made of a comfortable plastic material and customized to fit snugly over your teeth. In order 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. The Invisalign system can only work if the recommended guidelines are followed exactly! Aligners should be worn 20-22 hours per day throughout treatment. If patients neglect to wear the aligners as directed, it can impede the results and also add time to the orthodontic process.

Invisalign is at its most efficient when correcting many of the most common orthodontic issues. For some complex cases, Invisalign may not be a good option. A free consultation with Feil Orthodontics will allow us to determine your Invisalign eligibility.
