About Cosmo Dental Centre

Cosmo Dental Centre is a family dental clinic that serves as the primary source of dental treatment for all members of a family. We shall place a strong focus on preventative dental treatment in order to protect the dentition and prevent or postpone the onset of new episodes of dental disease. If therapy or treatment services are necessary that we believe are best handled by a professional, we will not hesitate to make a recommendation.

This office's rates are aligned with the current Ontario Dental Association fee guide. We would appreciate prompt payment and we encourage you to discuss any issues or concerns you have about our prices with us directly. We will also help you with the claims forms if you have dental insurance. Please do not hesitate to contact us if you have any more questions.

How We Like to Work?

The initial session is always designated for a thorough oral examination and the appropriate diagnostic data to establish the best treatment plan for each client. An examination will be done in the case of an emergency to identify your acute problem. Our goal will be to relieve your discomfort and restore your sense of well-being. At the second session, we will present you with our results as well as a potential treatment plan and cost estimate. We will also review your oral condition and explain our recommendations.

After your initial treatment, you will be placed on the post-treatment care list. When your appointment is due, you will be contacted and an appointment will be scheduled.

Our Guidelines

Cosmo Dental Centre is here to help you. We make every effort to make your visit as pleasant as possible. Here are the guidelines we adhere to:

  • Our role will be to identify your dental issues, treat them in a timely manner, and teach you how to maintain your oral health at home

  • The office may be closed from time to time to allow the staff to attend continuing dental education classes. Patients benefit directly when we implement the best diagnostic, therapeutic, rehabilitative, and preventative treatment available

  • To avoid misunderstandings and to grant consent for treatment, all children should be accompanied by an adult. These are young people and teens who rely financially on their parents or guardians

  • Please arrive on time for your appointment. To change an appointment, you must give at least 24 hours' notice, or you may be charged. Appointment fees are due at the conclusion of each visit

Please let us know if you have any suggestions. We always appreciate hearing from our patients.
