A whiter Smile,
your way

Over-the-counter whitening products often promise results but rarely deliver the bright, even smile you’re hoping for. At Saint City Dental, we offer professional teeth whitening that’s safe, fast, and customized for you.

As a trusted St. Paul teeth whitening dentist, we offer two professional options: in-office whitening for fast, noticeable results in a single visit, and custom take-home trays you can use on your own schedule. Both use POLA, a professional-grade whitening system designed to brighten your smile evenly while keeping sensitivity in check.

What's the difference between in-office and take-home whitening?

In-office whitening delivers fast results in about an hour, while custom take-home trays with POLA let you brighten gradually on your own schedule. Many patients choose one or combine both.

What to expect from
whitening treatment

  • Initial consultation to assess tooth shade and goals
  • In-office treatment for immediate results, or custom take-home trays for use at home
  • Professional POLA whitening for even, reliable brightening
  • Guidance on how to maintain brightness between treatments

Amazing - this is where you want to be! They 100% put the patient first, and assure you have everything you need to be comfortable. I'm a nervous patient, and I am telling you these people lead with heart. Make an appointment now!

Dr. Cassi and Saint City Dental are one of the best in the business! I was greeted with friendly smiles from their excellent staff and had a very short wait until they brought me back for my appointment. I would recommend this place to all my family and friends.

- Grant T.

I get quite nervous at the dentist (had bad experiences as a kid), but Dr. Rachel & Kelly help keep my mind off things. They are so gentle and kind…the best team around!

- Bonnie M.

Been coming to this dentist for 8 years, and I love them. I recently had my first dental issue of my adult life and really felt heard. I had mouth pain after a cavity was filled, and the practice listened and tried to help me. It was such a relief to be heard and helped when I was in pain.

- Sarah B.

“I highly recommend this dental practice. They are professional, calm, kind, and practical. I have worked with a variety of hygienists and dentists, and my visits have all been high-quality. It is clear folks here lead with integrity and put the best interest of their patients first.”
