Dr. Jay Nagamatsu and Dr. Dorothy Sonya

Become a Patient

We work with patients of all ages and backgrounds, and we specialize in working with patients that require a little extra care or attention, including those with special needs. We determine the best course of treatment based on your unique situation, including reviewing your medical and dental history, giving you a clinical examination, and taking digital photos of your face and teeth. We also work closely with your general dentist, and in certain situations with periodontists (gum specialists) and oral surgeons.

We pair each patient with the same assistant throughout the entire treatment. Our patients know that they can call their orthodontic assistant with any questions or concerns they might have, and they know what to expect when they come in for each appointment.Here's how our new patient process works:

Step 1 Consultation & Exam (1 hr)

Your first visit with us is a consultation where we perform a clinical exam and usually take digital photos. We use the information from your exam and images to outline your preliminary treatment plan.

Step 2 Records (1 hr)

After the consultation, the next step is to take diagnostic records to determine the best course of treatment. Complete diagnostic records normally include:

  • A medical/dental history
  • Clinical exam
  • Digital photos
  • Study models of your teeth (in select cases, this includes 3D printed versions) 
  • Digital x-rays

We also use these records to track the progress of your treatment over time.

Step 3 Case Presentation (1 hr)

Once Dr. Nagamatsu or Dr. Sonya have reviewed your case, a Treatment Coordinator will discuss your treatment options and plan in detail, including the cost for your particular case.

Step 4 Appliance Fitting Appointment (1 to 2 hr)

During your first orthodontic appointment, you will get your appliance.

Step 5 Regular Appointments (10 to 40 min)

After you receive your appliance, you'll see us at regular intervals 4 to 8 weeks apart for an adjustment, which takes 10 to 40 minutes. Patients are seen by appointment only, so you’ll need to book your appointments ahead of time.

Fees & Policies

The cost of treatment depends on the complexity your case. We’ll discuss fees and payment options before starting any treatment. We do our best to ensure that your treatment is affordable, and offer different payment plans to suit different budgets.


In an effort to keep orthodontic fees down while maintaining the highest level of professional care, we have established this financial policy:

  • If full payment is made at the onset of treatment, we will offer a fee discount.
  • To fit your individual needs, financial arrangements can be made to extend your payment over a period of months.
  • For your convenience, we accept payment by cheque, Interac, Visa, and MasterCard.
  • In cases of serious delinquency, treatment will be discontinued, although we will make every effort to accommodate patients with temporary difficulties.



If you have insurance, we will help you to determine the coverage you have available. Professional care is provided to you, our patient, not to an insurance company. Thus, the insurance company is responsible to the patient and the patient is responsible to the doctor.

Frequently Asked Questions About Orthodontic Treatment

How often should I see my family dentist during orthodontic treatment?

It’s important to continue to see your family dentist every 6 months for dental cleanings and checkups.

How do orthodontic appointments work?

Regular Orthodontic Appointments

Orthodontic appliances have to be adjusted and monitored every few weeks for treatment to proceed as planned.The length of appointments varies depending on the stage and progress of treatment. Some office visits may conflict with work or school. In order to balance the need for regular appointments with the need to minimize missed school and work hours, we have designed our office schedule as follows:

Short Appointments (15 min)

The majority of appointments will be short and are scheduled throughout the day. In order to see the maximum number of patients after 3 PM during the school year, only short appointments are scheduled. As a result, we cannot use a chair for a long appointment after 3:00pm.

Long Appointments (30 min+)

Appointments requiring 30 minutes or longer are scheduled in the morning or early afternoon. These appointments are less frequent, and we try to minimize the number of times these are needed. We will provide school / work excuses for these appointments.

Emergency Appointments

Emergency / repair visits are available during office hours; however, times may not be open after 3:00pm for these appointments. The doctors are on-call when the office is closed and can be paged by calling our office number and following the prompts.

Late Arrivals

In order to provide the best quality care possible, we make every effort to be on time and see every patient at their scheduled time. We ask that you extend the same courtesy to us. Please note that if you are late, we may not be able to see you right away, or may need to reschedule your appointment to another day.

Missed / Cancelled Appointments

It may be difficult to reschedule you if you miss or cancel an appointment because most appointments are made 4 to 8 weeks in advance. If you cannot keep an appointment,  please notify us immediately. Cancel only if it is an emergency. We'll work with you to find a new time as soon as is possible. We want to stress the importance of a regular appointment schedule so treatment is not delayed.

Appointment Reminders

We provide email reminders 2 days prior to your scheduled appointment. By logging in on our website, you also have 24-hour access to appointment details.

Do I need a family dentist referral to see Drs. Nagamatsu & Sonya?

A person of any age, including adults, can benefit from orthodontic treatment: at White Rock Orthodontic Center, about 40% of our patients are adults.

Orthodontics is the science of moving teeth and jaws that are misaligned. As orthodontists, we use our expertise and a variety of orthodontic appliances to guide your teeth and jaws into the correct position.
