WSIB Dental Injury Ontario: Coverage, Treatment, and Appeals

A WSIB dental injury in Ontario can happen in an instant - a fall on the job, a struck face, a machinery accident, or even biting down on a hard object during a workplace incident. When teeth are chipped, knocked loose, or lost entirely, the medical costs can add up quickly. The good news is that the WSIB may cover necessary dental treatment when the injury is directly related to your work.

What counts as a WSIB dental injury in Ontario?

The WSIB covers dental services that are required as a direct result of a work-related injury or disease. According to the WSIB's Dental Entitlement policy (Operational Policy Manual, Document 17-03-03), dental services are approved if they are needed because of a workplace accident or occupational disease affecting the teeth, gums, or jaw.

Common workplace dental injuries include:

Chipped or fractured teeth from a fall, being struck by an object, or a machinery accident
Knocked-out (avulsed) teeth from an impact or fall on the job
Displaced or loosened teeth from trauma to the mouth area
Jaw injuries that affect dental function or cause tooth damage
Dental damage from an occupational disease such as industrial-acid exposure affecting tooth enamel
Broken dentures or dental appliances in a work-related accident

The key requirement is that the dental injury must arise out of and in the course of employment. A pre-existing dental condition does not automatically disqualify you, but the workplace event must have caused or materially worsened the damage.

Emergency treatment: what to do immediately after a dental injury

If you suffer a dental injury at work, your first priority is your health. For emergency dental care after a workplace accident, the WSIB policy states that emergency services must be provided within 48 hours of the injury. The dentist who provides emergency care must inform the WSIB of the services provided.

Emergency services under WSIB coverage are intended to:

Make you comfortable and relieve pain
Make the condition functional and stable
Prevent deterioration of the teeth

What to do right away:

Seek emergency dental care immediately - go to a dentist, emergency room, or walk-in clinic
Tell the dentist the injury happened at work so they can document the work connection
Report the injury to your employer as soon as possible
Keep detailed records of the incident, treatment, and costs
File your WSIB claim promptly - workers generally must report a work injury within six months

Do not delay. Emergency treatment must happen within 48 hours for WSIB coverage. Tell your dental provider the injury happened at work so they can properly document the work connection in their records.

How to report a WSIB dental injury

Reporting a workplace dental injury follows the same general process as any WSIB claim, with a few dental-specific considerations.

Step 1: Get emergency care. Go to a dentist or emergency room immediately. The treating dentist should provide emergency care within 48 hours and notify the WSIB.

Step 2: Tell your employer. Report the injury to your supervisor or employer as soon as possible. Provide a factual description of when, where, and how the injury happened. Your employer may need to submit an Employer's Report of Injury/Disease (Form 7).

Step 3: File your claim. You can report your injury to the WSIB directly. Your health care provider may also submit a Health Professional's Report (Form 8).

Step 4: Work with your dentist on the WSIB dental report. Once the acute phase has passed, your dentist must provide the WSIB with a Dental Report (Form 0278A). This form includes an outline of your pre-accident dental condition and details about the proposed treatment plan for restoring your teeth to their pre-injury condition.

Step 5: Get WSIB authorization before non-emergency treatment. While emergency care can proceed immediately, all non-emergency dental services must be authorized by the WSIB before they begin. Your dentist should submit the treatment plan for approval.

What the dentist needs to document

For a successful WSIB dental claim, your dentist should document:

The specific teeth affected and the nature of the damage
Your pre-accident dental condition (existing fillings, crowns, missing teeth, etc.)
How the workplace accident caused or worsened the dental injury
The proposed treatment plan and estimated costs
Why each proposed treatment is necessary to restore health and chewing function to pre-injury condition

Browse verified WSIB lawyers and paralegals on ClaimIt who can help you if the dental claim process becomes complicated.

What dental treatments does WSIB cover?

The WSIB pays for necessary dental services according to an approved fee schedule (refer to WSIB policy 17-03-01, Health Care Fees). The goal is to restore the health and chewing function of your teeth to their pre-injury condition.

Covered treatments

Based on the WSIB's Dental Entitlement policy, covered treatments may include:

Emergency dental care within 48 hours of the injury
Provisional crowns for traumatized teeth - it is standard practice to protect injured teeth with provisional crowns for a minimum of three months following the accident
Final crowns - authorized after the provisional period if the teeth are still vital
Fillings and restorations for chipped or fractured teeth
Root canal treatment if needed due to the injury
Tooth extraction if the tooth cannot be saved
Denture repair or replacement if broken in a work-related accident
Bridgework to replace missing teeth when needed to restore function
Ongoing maintenance - if your teeth are injured, the WSIB may pay to keep them in repair for your lifetime, provided there is no evidence of carelessness or misconduct on your part

What WSIB does not cover

The WSIB does not pay for:

Restorative services for cosmetic reasons alone
Treatment for pre-existing dental disease that was not caused or worsened by the workplace injury
Full-mouth extraction and replacement of teeth that were already unsound before the accident

Timing of treatment

The WSIB sets specific timelines for dental treatment after approval:

Approved temporary treatment should begin within 90 days of the injury
Approved permanent treatment should begin within one year
If treatment does not begin within these timeframes and your condition has deteriorated, the WSIB may limit entitlement to what was originally approved

Records and receipts: what to keep for your dental claim

Strong documentation can make a significant difference in your WSIB dental claim. Keep copies of everything.

Essential records to maintain

Incident report - write down exactly how the injury happened, including the date, time, location, task, and witnesses
Employer report - a copy of any report you submitted to your employer
Emergency dental records - the initial clinical notes, X-rays, and treatment records
Dental Report Form 0278A - your dentist's report to the WSIB
Pre-accident dental records - if available, records showing the condition of your teeth before the workplace accident
Treatment plan and cost estimates - from your dentist
Receipts for all dental expenses - including examinations, X-rays, treatments, and medications
WSIB correspondence - all letters, decisions, and claim numbers
Photographs - photos of the dental injury taken soon after the incident

Why pre-accident records matter

The WSIB needs to know your pre-accident dental condition to determine what treatment is covered. If you have recent dental records, X-rays, or photos showing your teeth before the workplace injury, these are extremely helpful. They help the WSIB distinguish between damage caused by the accident and pre-existing dental disease.

If you do not have pre-accident records, your dentist may still be able to provide an assessment of what was likely present before the injury based on clinical findings and reasonable professional judgment.

What happens if WSIB denies your dental claim?

WSIB may deny a dental claim for several reasons. Understanding the reason for denial is the first step toward a successful appeal.

Common reasons for dental claim denials

The work connection is unclear - the incident was not well documented or reported late
Pre-existing dental disease - WSIB concludes the damage was present before the workplace accident
Insufficient evidence - missing dental records or incomplete documentation
Late reporting - the injury was not reported within the required timeframe
Treatment was not authorized - non-emergency treatment proceeded without prior WSIB approval
Cosmetic-only treatment - WSIB determines the proposed restoration is for appearance rather than function

Your appeal options

If the WSIB denies your dental claim, the appeal process follows the same two-level system as other WSIB decisions:

Level 1: Internal Review by the Appeals Resolution Officer (ARO)

You generally have 30 days from the date of the decision to request an internal review
The ARO takes a fresh look at your case and any new evidence you submit
There is no fee to request an internal review
WSIB aims to resolve most ARO reviews within 60 to 90 days

Level 2: Appeal to the Workplace Safety and Insurance Appeals Tribunal (WSIAT)

If the ARO upholds the denial, you can appeal to the independent WSIAT
WSIAT is separate from WSIB and has authority to overturn WSIB decisions
You generally have six months from the ARO decision to appeal to WSIAT

For a complete walkthrough of the appeals process, see ClaimIt's WSIB claim denied appeal steps guide.

What to do if your dental claim is denied

Read the decision letter carefully - identify exactly what was denied and the stated reason
Protect the objection deadline - note the deadline in the letter and act before it passes
Request your claim file - review what evidence the decision-maker relied on
Gather additional evidence - focus on records that directly address the reason for denial. If the issue is the work connection, get an incident report or witness statement. If the issue is pre-existing dental disease, get pre-accident dental records or a dental opinion explaining the change
Consider professional help - a WSIB lawyer or paralegal experienced with dental claims can help you build your appeal

When to speak with a WSIB lawyer or paralegal about a dental claim

Professional help may be especially valuable for dental claims because dental evidence, pre-existing conditions, and treatment plans can become technical quickly. Consider speaking with a representative if:

Your injury happened gradually (not one clear accident)
Your employer disputes that the dental injury happened at work
You have significant pre-existing dental disease
The WSIB denies your claim
You need dental treatment beyond basic emergency care
An appeal deadline is approaching
The WSIB limits your approved treatment

Frequently asked questions about WSIB dental injury claims

Does WSIB cover dental injuries from workplace accidents?

Yes, the WSIB covers necessary dental services required as a direct result of a work-related injury or disease. This includes chipped teeth, knocked-out teeth, jaw damage, and broken dental appliances. Emergency treatment must be provided within 48 hours of the injury.

Do I need WSIB approval before getting dental treatment?

Emergency treatment does not require prior approval, but the dentist must notify the WSIB of the services provided. All non-emergency dental services must be authorized by the WSIB before treatment begins. Your dentist should submit a treatment plan (using Form 0278A) for approval.

What if the WSIB denies my dental claim because of pre-existing dental issues?

You can appeal the decision. Pre-existing dental disease does not automatically mean your claim will be denied, especially if the workplace accident caused additional damage or worsened an existing condition. You may need dental records showing your pre-accident condition and medical evidence explaining how the workplace injury changed things.

Does WSIB cover emergency dental treatment on weekends?

WSIB policy requires emergency dental care within 48 hours of a work-related dental injury. If your regular dentist is unavailable, go to an emergency dental clinic or hospital emergency room. Tell the treating provider the injury happened at work.

How long do I have to file a WSIB dental claim?

Ontario workers generally must report a work-related injury to the WSIB within six months. For dental injuries specifically, emergency treatment should happen within 48 hours. The sooner you report, seek care, and file your claim, the stronger your case will be.

Will WSIB pay for dental implants after a workplace injury?

Treatment depends on what is necessary to restore health and chewing function to the pre-injury condition. Your dentist should submit a treatment plan explaining why the proposed treatment is needed. The WSIB makes coverage decisions based on the specific facts of your case and the Dental Entitlement policy.

Can I choose my own dentist for a WSIB dental claim?

You can receive treatment from any licensed dentist. Your dentist will need to complete the required WSIB forms (Form 0278A) and submit treatment plans for approval. If you see a dentist who is not familiar with WSIB claims, make sure they understand the documentation requirements.
