health • integrity • smiles

NJC Dentistry provides comprehensive care for all of our clients through an honest and personal approach. Our practice at NJC Dentistry is founded on three principles: integrity, health, and smiles.

“Everyone smiles in the same language.”

Comprehensive Dentistry Services

Dr. Nancy Jane Cashman and the team at NJC Dentistry are skilled professionals, covering all  your dental needs from checkups to restoration.


Family Dentistry

Serving you and your family with a smile. Our welcoming atmosphere puts your children at ease, while our professionalism gives you the peace of mind that your family’s dental health is in good hands.

Dental Health

From checkups to whitening, we help you maintain a great smile through routine care and preventative treatments. Our friendly, capable team will help you stay healthy, and flash that smile with confidence.


Emergency Care

It happens. A tooth knocked out while playing sports, a loose filling, a crack or chip. Dental pain can be challenging. We are here to get you back to smiling as soon as possible.


A Perfect Smile

A great smile begins with good dental health. Our cosmetic dentistry services apply when more than a cleaning is needed. We restore more than your teeth, we restore your smile.

“Smile if you want a smile from another face.”

We are a small, non-corporate practice located right where NE Minneapolis meets Columbia Heights, Minnesota at 3844 Central Ave NE. From the moment you walk into our office you will notice a difference at NJC Dentistry.

An Artful Practice

We celebrate our commitment to our community by showcasing local artists throughout our practice. Our art-filled practice is full of light and laughter in comfortable atmosphere that once was a stucco house. We enjoy our work and invite you to sit back, relax and find comfort and ease while we serve you with a smile. As a creative type herself, Dr. Cashman enjoys the fine art of dentistry and creating smiles.

Environmentally Friendly

Our commitment to beauty extends beyond our walls. We are committed to reducing our impact on the environment and are continually seeking ways we can make our practice more environmentally friendly. Paperless charting, digital radiographs (x-rays with less radiation, no toxic developing chemicals, and less materials waste), minimizing mercury exposure to be conscientious of our water/river/streams, and recycling are all important priorities to Dr. Cashman. We use local labs for our cases and our composite white fillings are BPA-free. Patient education and prevention of disease is the key.

“Sometimes your joy is the source of your smile,
sometimes your smile is the source of your joy.”
