Welcome to Seven Sails Dental Centre!

We're so happy you're here.


With pristine, state-of-the-art facilities and a central location just a few blocks from Nanaimo's hospital, Seven Sails Dental Centre is one of Nanaimo's top dental clinics.

Our dentists have a combined experience of almost 70 years, and we treat our patients how we'd want to be treated.

Choosing a dental office is a big step. You're hoping to find a clinic you can trust, with highly skilled professionals who communicate clearly.
The people in our shop have decades of experience and will always talk with you as equals. 

Our goal is to help you best care for your teeth, as a beautiful smile that functions optimally is important for health, quality of life, and self-esteem.

Dentists scare you? You're not alone. At least a third of us fear the dentist, and some say much more. We get it. So, Seven Sails takes managing pain and anxiety very seriously. Let us know how you're feeling and what you need, and we'll prove to you that we can make your dental experience better. We have many options available and will do our very best to make sure you're as comfortable and calm as possible.

Let us look after you.

At Seven Sails, your knowledge and understanding are of utmost importance to us.

We believe that knowing what's going on will help you feel more relaxed and confident in our care. So, our workstations are equipped with intraoral cameras and an intraoral scanner for taking pictures of whatever needs attention, at any point in the procedure. When we magnify the images on a computer screen, patients are often 'mindblown,' exclaiming, "Those are my teeth?!" Yup. We love showing you what's going on. And when multiple treatment options are available, we'll break them down together so you can make the best decision for yourself.

Methods of Payment

We accept third-party insurance, MasterCard, Visa, and cash. Note that not all procedures are covered by insurance. However, our exceptional staff can assist you by sending pre-authorizations to your dental plans before your next treatment commences (if required).

Dr. John Olesen

John Olesen completed his basic dental training at UBC in 1983. He has been based in Nanaimo since graduating and now has 40 years of experience, first at Chase River Dental before founding Seven Sails with his wife and dental partner, Dr. Maria Furlong. With Dr. Furlong, he has been involved in many study clubs over the years to further dental training.

Beyond being venerated for his remarkable skill level and speed, with every appointment, John prioritizes patient education. He believes wholeheartedly in ensuring that each patient knows what's being done, how it's being done, and why.

John enjoys learning about each patient's unique story, and is extremely popular for his enthusiasm and fun-loving energy.

Dr. Maria Furlong

Dr. Maria Furlong completed her dental training at UBC before moving to Vancouver Island. She's worked alongside John since then, and has accumulated over 25 years of experience treating patients. She has a special passion for working with children (and has raised four kids with John — one of whom is currently in dental school). Known for her gentle, personable manner and meticulous, careful hand skills, she's an empathetic and sensitive person ... who would probably be afraid of dentists if she weren't one.

Understanding dental fears, Dr. Furlong offers nitrous oxide (laughing gas) and oral sedation to patients who might benefit from its use. She strives to make dental visits a positive experience for each and every patient.
