Non-emergency dental services under the Healthy Smiles Ontario (HSO) program are gradually restarting.

Dental care providers are continuing to monitor COVID-19 to stop the spread in their communities and to carefully and gradually restart services under the Healthy Smiles Ontario (HSO) Program. In person dental visits may still be limited in this time for the safety of dental care providers and HSO patients.

You can continue to apply for the HSO program during this period.

If your child or youth is enrolled in the HSO program, please contact a HSO-participating dental provider or your local public health unit by phone for assistance with your dental needs and more information on the gradual restart of services in your area.

Find a participating dentist

If you have a dentist, contact their office to find out if they participate in Healthy Smiles Ontario. If you don’t have a dentist, your local public health unit can help you find one.

Emergency dental care

To qualify for emergency/essential dental care, you must:

  • have a clinical need
  • be able to show financial hardship. You will be asked some questions about how you or your family would be affected if you had to pay for dental treatment. For example, would you be able to pay household bills if you had to pay for dental treatment?

To apply for emergency care, contact your dentist’s office or your local public health unit to find out if they participate in Healthy Smiles Ontario. If you don’t have a dentist, contact your local public health unit for help.

Children receiving emergency and/or essential care are covered for 12 months from their date of enrollment. They must re-apply at the end of 12 months to determine if they’re still eligible.

Children with dental insurance

Even if your child already has dental insurance coverage, they may still be eligible for the program. You can apply in the same way that other families apply. You may be asked for your insurance information when you go to your dental provider for treatment.

Elementary school screenings

Children in kindergarten and Grade 2 at public elementary schools can get free routine dental screening.

Local public health units will visit these schools throughout the year to do the screening. Each school schedules its own time and date for the visit.

Why we screen these kids

Children in kindergarten may not have seen a dental care provider before. This screening ensures all kids get that first visit.

Children in Grade 2 have their first permanent molar (back) teeth. This screening can help identify and prevent decay.

If emergency care is needed

A screening can also help identify if your child needs emergency treatment. In these cases, a letter will be sent home with your child.

You can apply to Healthy Smiles Ontario to see if your child is eligible to receive this care for free.

Notifying parents

You’ll be notified at least two weeks before your local public health unit visits your child’s school. The school and public health unit choose how to notify parents. You may hear by:

  • letter sent home with your child
  • email
  • announcement on the school’s website

Opting out

You can opt out of the screening, if you don’t want your child/children to participate

In your notification, you’ll find instructions for opting out by:

  • letter (address given in notification)
  • phone (contact name and number given in notification)

Make sure to opt out as soon as you get the notification.
