An Orthodontist is a specialist in dentistry, more specifically in the diagnosis, prevention and treatment of dental and facial irregularities. Orthodontists limit their practice to the treatment of all types of malocclusions (crooked or crowded teeth and/or bad bite or improper jaw relationship) in children, adolescents and adults.

To become a specialist, an Orthodontist first has to be a general dentist and then successfully complete an additional three year full-time specialty residency program, accredited by the Canadian Dental Association (CDA). Then, to be conferred the Orthodontist or Specialist title, the examination by the Royal College of Dentists of Canada must be passed.

Dr. Lavoie, for his part, chose the University of Montreal to carry out his studies in order to evolve in the world of dentistry.

Around the age of 7, the orthodontist should be able to easily identify certain problems that need to be corrected at a young age, which is why we recommend a first consultation at this time. However, no matter how old your child is, it is never too late to consult with Dr. F. Lavoie to prevent any issues that can arise. In any case, the type of treatment suggested will be determined by the severity of your child’s malocclusion.

Absolutely! No matter your age, orthodontics are possible at any time. The only criteria to meet is to have healthy teeth, gums and jawbones. If you respect this condition, you can improve your smile with the help of our various orthodontic treatments.

The cost associated with your orthodontic treatment will depend on the type of treatment received (Invisalign treatment, traditional braces, ClearCorrect treatment, etc.), the type of malocclusion to correct as well as the severity of this malocclusion. To ensure you enjoy the benefits of orthodontics – that is, a bright smile that will last a lifetime – we offer interest-free payment plans that are highly flexible to accommodate your budget.

Plusieurs types de traitements sont disponibles à la clinique du Dr. F. Lavoie. Selon la sévérité de la malocclusion à traiter, l’orthodontiste déterminera avec vous le meilleur traitement à mettre en place. Que ce soit le traitement Invisalign®, le traitement ClearCorrect ou des broches traditionnelles en métal, nous vous garantissons un sourire éclatant et en bonne santé. Discutez avec votre orthodontiste pour connaître le traitement qui s’applique le mieux à votre condition. 

The time required to complete an orthodontic treatment varies greatly depending on the complexity and severity of your condition. During your consultation with our team, Dr. F. Lavoie will be able to assess the estimated duration of your treatment, in addition to guiding you towards the best option according to your oral situation. In general, orthodontic care can take up to 24 months, or 2 years.
