Declaration of Emergency - Toronto Mayor John Tory:

Dear Valued Patients, Parents, and Families:

In light of the current COVID-19 pandemic; in keeping with our priority to maintain the absolute safety of our staff, patients, and parents; and with recommendations from our regulatory body (Royal College of Dental Surgeons of Ontario - RCDSO), we at Richmond Hill Orthodontics and Dr. Jeffrey Tse have decided to postpone all non-essential office visits.  As such, ALL previously scheduled appointments are hereby cancelled until further notice.

The announcement by the RCDSO to immediately stop all non-essential and elective dental procedures was made on March 15, 2020, with the ultimate goal to slow down the spread of the COVID-19 virus as outlined by the Chief Medical Officer of Health for Ontario.  This temporary clinic closure is expected to last at least until the "State of Emergency" has been terminated and lifted by the City of Toronto / Province of Ontario.

The orthodontic / dental profession is highly regulated when it comes to cross-contamination and infection control, and we always operate in accordance with all regulations with that respect.  However, orthodontists and dental assistants / hygienists are very likely to be vulnerable to this particular virus, as we are exposed to a high quantity of aerosol and saliva particles.  Due to its high infectiousness and the absolute need to slow down the spread of this virus, the responsible action is to limit the possible exposure to everyone and stay safe.

Though this an inconvenience for all involved, delaying orthodontic visits for a short period is extremely unlikely to cause any significant harm, as long as you are brushing your teeth regularly, keeping ideal oral hygiene standards, and following the instructions which are summarized below.  These instructions are for those under active treatment using fixed braces / appliances, Invisalign®, retainers, or in interceptive treatment with an expander.  Please follow these instructions to help minimize any potential problems:

  • Maintain excellent oral hygiene, including brushing after meals and flossing daily.
  • Consider purchasing a fluoride rinse (Listerine®) from your local pharmacy / store.
  • Avoid excessive consumption of sweetened beverages or foods (candies, etc).
  • For patients in fixed braces, avoid hard foods and use orthodontic wax (as needed).
  • If you have an expander or other device that requires you to activate it - STOP turning the expander or appliance until we resume normally scheduled visits.
  • If you are in fixed braces or Invisalign® and are using elastics, continue wearing elastics and follow the instructions already provided at your last visit, such as the pattern of wear of elastics.
  • For those who have finished their treatment and are wearing retainers, follow the instructions that were provided at your last visit regarding the wear-time of your retainers.
  • If your fixed / permanent retainer(s) break or become loose, wait until we resume normally scheduled visits and we can repair the glue.
  • For Invisalign® patients, continue wearing your most current aligner (with elastics if applicable) until we resume normally scheduled visits.

If you have an emergency that requires our attention, it would be ideal to send us an email ( along with a picture.  Hold your lips apart and ask someone to take a picture (with flash) of the affected area to identify the problem(s) so we can advise you accordingly.  In the meantime, the advice is to avoid or minimize emergency visits until it is deemed safe to re-open by health officials and the RCDSO.

We certainly understand that this unforeseen closure may delay your treatment.  However, we want you to be assured that we will do our utmost to complete your treatment as expeditiously as possible, as soon as we are able to resume normal operations.

Ultimately, in the face of this global pandemic, it is each and everyone’s responsibility to help stop the spread of the COVID-19 virus.  Be safe, healthy, and take good care of your loved ones.

Many thanks for your kind understanding and cooperation during this unprecedented time period,

Dr. Jeffrey Tse & Team
Richmond Hill Orthodontics
