What is Healthy Smiles Ontario?

What is NOT Covered Under the Healthy Smiles Ontario?
The HSO program does not cover cosmetic or aesthetic dentistry, which includes:
- teeth whitening,
- orthodontics (such as braces),
- dentures (except specific anterior tooth replacement situations).
These services focus on appearance rather than health and function. Thus, families seeking these treatments would need to pay privately or through separate insurance coverage.

How to Apply for Healthy Smiles Ontario
You can apply for Healthy Smiles Ontario online or by mail, depending on your circumstances. When your child enrolls in HSO, they get coverage each year from August 1 to July 31, or until the day before their 18th birthday, whichever comes first.
The expiry date is shown on the front of the card. If the card expires and your child is still eligible, you can reapply at any time during the benefit year.
Apply for Healthy Smiles Ontario Online
This is the fastest application method, through ServiceOntario’s online portal, which works for families who:
- Have a Social Insurance Number (SIN) or Temporary Taxation Number (TTN)
- Filed a tax return with the CRA in the previous year
- Live at a valid Ontario address
To complete, you need your child’s date of birth, your SIN or TTN, and your family’s net income from your latest tax return. If you have a spouse or common-law partner, they need to be there to provide an e-signature. Note that each adult must use a separate email address.
Then, visit the ServiceOntario website and search for “Healthy Smiles Ontario application” to find the online form. It takes approximately 15 minutes to complete and must be done in one session, as there is no option to save it for later.
After you submit it, Accerta will mail your Healthy Smiles Ontario dental card to you within 10-15 business days.
Apply for Healthy Smiles Ontario by Mail
This method typically takes several weeks longer to process than online submissions. To apply for HSO by mail, families can:
- download the General Application Form from the Ontario government website, or
- obtain a copy at their local public health unit or a ServiceOntario location.
After that, fill out your child’s information and family income details, as you would in the online method. Then mail the completed form to Healthy Smiles Ontario at 33 King Street West, PO Box 645, Oshawa, Ontario L1H 8X1.
No SIN/No Tax Return Exception
If you do not have a SIN or did not file a tax return last year, apply, download and fill out the Application Through Guarantor Form. Besides, you need to have your guarantor complete and sign their section.
Eligible guarantors include healthcare providers, teachers, social workers, lawyers, accountants, police officers, and other professionals listed on the form. They must be a Canadian citizen, at least 18 years old, and in good standing with their respective regulatory body.
Mail the completed guarantor form to the Oshawa address listed above. Once approved, you will receive an HSO dental card by mail. Bring it to each dental appointment to access free services.
Ontario Works First Nations Exception
If you get Ontario Works and live in a First Nations community, you need to enroll on your own. Do it by downloading the Ontario Works First Nations Verification Form and then mailing it to Healthy Smiles Ontario at Station P, PO Box 2286, Toronto, Ontario M5S 3J8.

How Healthy Smiles Ontario works with Other Dental Plans
When your child has multiple dental coverage options, HSO is the payer of last resort. Accerta handles applications, issues dental cards, processes claims, and coordinates benefits with other insurances.
If you have private dental insurance through your employer or a purchased plan, your child might qualify for HSO. They can work together to give extra support when families provide insurance details during dental visits.
Similarly, children can be enrolled in both HSO and the Canadian Dental Care Plan (CDCP). CDCP will be the main payer, while HSO may cover extra costs not paid by CDCP.
Local Public Health Units will help with enrollment, assist families in finding dentists, and offer dental services where available. For general inquiries, you can reach ServiceOntario at 1-844-296-6306.
The Bottom Line
Healthy Smiles Ontario helps prevent minor dental issues from developing into more serious problems. Without it, children might miss out on necessary care like cleanings and checkups, which can lead to painful cavities, infections, and more expensive health issues later on. Therefore, do not miss the opportunity to apply for this program.
FAQs about Healthy Smiles Ontario
Can children receive HSO when they are not yet enrolled?
Yes, children can receive help with urgent dental issues even if they are not enrolled. Contact your local public health unit or a participating dental provider for assistance.
Does HSO cover cases that happen outside regular office hours?
Yes. Healthy Smiles Ontario covers dental emergencies outside regular hours, but it depends on your child’s program and the emergency.
What if my family’s income increases during the HSO benefit year?

What documentation do I need to bring to the first dental appointment?
Bring your child’s Healthy Smiles Ontario dental card (required for all appointments), your child’s valid Ontario health card, and any relevant medical or dental history. If your child takes medications or has health conditions that the dentist should be aware of, bring a list or copies of relevant medical records.
What if families need to update their information on HSO?
If your family situation changes during the year, such as a move or changes in who lives with you, contact your local public health unit or the ServiceOntario INFOline to update your information. Keeping your contact details up to date helps ensure you receive timely renewal reminders and important program updates.
Where can families find participating dentists for HSO?
Families can find participating dentists through the online provider directory at ontario.ca/healthysmiles, by calling the ServiceOntario INFOline at 1-844-296-6306, or by contacting their local Public Health Unit.
Is there a cost associated with using Healthy Smiles Ontario?
Healthy Smiles Ontario offers free dental care for eligible children, but families must pay for any services not covered by the program.
What if I disagree with an HSO coverage decision or denial?
If you disagree with an HSO coverage decision or denial, you can appeal. First, contact Accerta, the program administrator, to find out why your application was denied. If your first appeal is unsuccessful, you can request a formal review.
