Finances and Dental Insurance

Do We Accept Your Insurance?

The answer is, most likely, YES! We accept almost all major dental insurance plans. Our dental office employs a number of insurance experts to navigate the ever-changing dental insurance landscape and we work hard to maximize your dental benefits. While this requires a significant investment in manpower and continuing education on our part, we know that this service is immensely important to our patients. We will file your insurance claim, track it, and follow up on any delays so that you don’t have to. Of course, at all times, we will provide you and your family with the financial details relating to your treatment so that you can make informed decisions.

No Dental Insurance? No Problem!

For a limited time, we are offering a free, no obligation, new patient experience, which includes consults, a comprehensive exam, and new patient digital x-rays and photos. We are comfortable making this offer, valued at $300, because we are confident that if we show you all that we have to offer, we will have a loyal client for life.

What Sets Us Apart

We aren’t your standard dental office. Our experienced multi-doctor team, state-of-the-art facility, technology, and patient-oriented service approach set us head-and-shoulders above our competitors.

We take great care to remain at the forefront of dentistry, constantly updating our standards and practices to make sure that all of our patients receive the most modern, conservative care possible. This makes your dental visits more effective and efficient.

Dr. William Olafson and Dr. Jacinthe Giroux take great pride in helping our patients achieve optimum oral health and in creating smiles that you can be proud of. Come to our dental office today to learn firsthand just how seriously we take our work at Columbian Square Dental.

Your First Dental Visit

To maintain optimal oral health, we recommend that both children and adults see their dentist at least once every six months. Frequent check-ups allow us to monitor your oral health and to screen you for early signs of any problems like cavities, gum disease, and oral cancer.

First appointments with us generally last about an hour and include a full, comprehensive exam that includes digital x-rays and photos. This will give us the tools necessary to gain a complete understanding of your dental health and will help us to diagnose and treat any existing conditions that you have such as tooth decay or gum disease.

Our friendly doctors and team make first dental visits relaxing, enjoyable experiences. Our modern, patient-focused approach to dentistry keeps our patients coming back to us again and again well after their first visit. To schedule your first visit with Columbian Square Dental, click here!

Flexible Payment Options

Aside from accepting cash, check and all major credit cards, we offer a number of payment options so that paying for treatment is as easy and convenient as the treatment itself. While we make sure that your insurance benefits are maximized, we also offer a number of flexible in-house and third party payment options. Care Credit® offers flexible payment options that many of our patients use so that they can get the smile they want today!

Privacy Policy

At Columbian Square Dental we make it our priority to meet and exceed all state and federal guidelines for the maintenance of our facility and its contents, and our patients take notice. Our attention to detail ensures that our dental office is clean, safe, and organized at all times. We have invested in advanced sterilization equipment and technology to ensure that our instruments are sterile and designated for your exclusive use during each visit. Of course, our treatment rooms are sanitized between each use. However, we know that enlisting state-of-the-art technology is not enough, so we maintain a vigorous auditing and maintenance standard for all of our equipment with the use of spore testing being one such measure to confirm the safety and sterility of our equipment.

Today, more than ever, protecting our patients means more than maintaining the safety of each patient during their visit with us. Have you considered how your electronic information is protected? We certainly have! Our staff and IT systems are audited in real-time and all OSHA and HIPPA regulations and standards are met and exceeded at all times. We utilize a complete array of encrypted and secure IT systems to protect you and your personal health information and we promise not to share it with third parties without explicit permission from our patients or their guardians.
