Dear Patients,

On April 7th, the Government of Ontario declared a provincewide state of emergency-effective at 12:01 a.m. on Thursday, April 8th-in response to an increase in COVID-19 cases and intensive care admissions. Similar to the last state of emergency order, this announcement does not impact any of the dental care services we currently offer on-site at Artin Dental.

Your health and safety continues to be our number one priority. Since the start of the pandemic, we have implemented enhanced measures to ensure a safe environment for our clients and staff members.

Be safe
Artin Dental Team


I hope this letter finds you and your family well. We are all eager to return to work, yet happy to have been blessed with good health during this very difficult time for everyone.

I am happy to inform you that we are now able to once again provide dental care for you. The Ministry of Health has lifted the restrictions placed back in March. Our governing college in conjunction with the Chief Medical Officer of Health and the Provincial Government just released the guidelines that we must meet to ensure the safety of our patients and of our staff. While many things have changed since then, one thing has remained the same: our commitment to your health and safety.

During the past few weeks our doctors were available to advise and assist you, we were answering your calls/texts/emails, and even provided dental emergency treatment within the guidelines set by the Ministry of Health.

I regret that the pandemic has forced us to postpone everything except urgent care. Your oral health is our most important concern, and now we are ready to have you back for your dental care so that we can continue to protect your health.

We have been preparing for our return to practice, and I am certain that you will notice several changes to the way we will operate. Your safety and well being is our top priority, while we will continue to follow the sterilization procedures as before and in accordance to all guidelines set by Public Health, and the Royal College of Dental Surgeons of Ontario, we will be taking additional precautions.

They are as follows:

  • Appointments will be spaced out to allow for physical distancing between patients. That might mean less flexibility for scheduling your appointment, but it will also reduce the number of patients in the reception area at any one time.
  • Our team members will now conduct a screening with you before your appointment (via an online form), and this screening will be repeated and recorded once you are in for your appointment, in order to confirm your health status.
  • We have installed air purifiers with HEPA filter and PlasmaWave throughout the office.
  • You will be asked to remain outside the office until called
  • Only patients with an appointment will be allowed entry to our office, including reception area. Family members or friends will be asked to remain outside the office.
  • We ask that you wear a mask upon entering our office.
  • Your temperature might be taken upon entry to monitor your health status.
  • You will be asked to use hand sanitizer upon entry, and advised to touch nothing else. You will be escorted directly into the treatment room (there are many hand sanitizer dispensers around the office for you to use as needed.)
  • All reading material has been removed from our waiting room for sterilization difficulty
  • You will be asked to take all your belongings with you into the operatory, including coats, etc
  • Once seated you will be asked to use an oral rinse in order to avoid any bacterial/virus concentration in your mouth.
  • Once treatment has been completed, the practitioner may reserve your next appointment in the operatory, in order to avoid any lengthy stops at front desk.
  • Appointments will be arranged to encourage social distancing between patients. We may therefore be limited to the times we may offer.
  • We will set time between patients, and stay on time for your appointments in order to avoid the number of patients in the office.
  • We are starting operations with reduced staff, due to social distancing limitations. We ask that you call/text/email us if you need to contact us, and prevent heading to the office first.


You can expect us to continue to provide you with excellent dental care, in an environment where we all feel safe.

Please feel free to call us at 416-364-4150 or email us at info@artindental.com for any questions you may have.

We hope to see you and thank you for your continued support and loyalty. You can expect the same from us.


Dr. Arash Ghassabei and Team of Awesome Professionals
