The type of dental work that you choose matters because dental insurance plans often reimburse these categories differently. A filling may receive one level of coverage, while a crown or denture may receive another, and waiting periods or annual maximums may apply. Here is a plain-language breakdown of what the terms usually mean in Canada.
What Restorative Dentistry Means
Restorative dentistry focuses on repairing damaged teeth or replacing lost teeth. Fillings, crowns, bridges, root canal-related restorations, and dentures can all fall within restorative care, depending on the treatment involved. This differs from preventive services such as routine examinations and cleanings and from primarily cosmetic treatments such as whitening or elective veneers.
Insurance companies may divide restorative procedures into basic and major categories when calculating benefits. The important point is that these are insurance classifications rather than universal clinical definitions, so the same procedure can occasionally be categorized differently from one plan to another.
What Counts as Basic Restorative Work
Basic restorative dental work generally includes common treatments used to stop disease, repair relatively limited damage, or preserve a natural tooth. Because insurance contracts differ, you should always confirm the classification in your own policy before assuming a treatment is covered as basic.
- Dental fillings repair teeth damaged by cavities and are commonly categorized as basic restorative treatment.
- Simple tooth extractions are frequently included within basic services, although surgical or complicated removals may be classified differently.
- Root canal therapy is treated as a basic service by many dental plans, but some policies place endodontic treatment in another category, so confirm your benefits before treatment.
- Repairs to existing restorations may qualify as basic care depending on the type of restoration and your individual plan.
If an infected or severely inflamed tooth needs endodontic care, Lawrence Dental Centre provides root canal treatment in Scarborough.
Basic work is often reimbursed at a higher percentage than major restorative care under private dental plans, but the exact percentage, deductible, and annual limit depend entirely on the policy.
The Cleveland Clinic defines it like this:
“Services typically covered under basic care include fillings, tooth extractions, root canals and gum disease treatment. Major care: This includes dental restoration, like a crown or surgical procedures like an implant, dentures and other kinds of oral surgery.”
What Counts as Major Restorative Work
Major restorative dental work usually involves more extensive reconstruction or replacement of damaged or missing teeth. These procedures tend to require more laboratory work, treatment time, or materials, which is why private insurance plans frequently place them in a separate benefit category.
- Dental crowns cover and protect substantially damaged teeth and are commonly classified as major restorative treatment.
- Dental bridges replace missing teeth by using neighbouring teeth or other supports to hold the restoration.
- Partial or complete dentures replace several missing teeth or an entire dental arch.
- Dental implants may be categorized as major treatment by plans that cover implants at all, although many plans exclude them or impose separate limits.
- Complex or surgical extractions may fall under a different benefit category than straightforward extractions depending on the insurer.
If a damaged tooth requires full coverage rather than a filling, a dental crown may be used to protect and restore the remaining tooth structure.
Major treatment is often reimbursed at a lower percentage than basic work and may also be subject to waiting periods, frequency limitations, or pre-treatment approval.
Why the Category Changes What You Pay
The distinction between basic and major dental work becomes important when you calculate your actual out-of-pocket cost. Many private dental plans reimburse eligible basic procedures at a higher percentage and major restorative procedures at a lower percentage, but there is no universal Canadian percentage that applies to every policy.
Your plan may also have an annual maximum, the most it will reimburse during a benefit year. Some policies impose a waiting period before major restorative coverage becomes available, particularly for newly enrolled members. Others may require a predetermination, where the dentist submits the proposed treatment and estimated fee before work begins so the insurer can indicate what it expects to cover.
Before agreeing to significant treatment, ask your insurer:
- Which benefit category does this exact procedure fall under?
- What percentage of the eligible fee is reimbursed?
- How much of my annual maximum remains?
- Does a waiting period apply?
- Should a predetermination be submitted first?
Getting these answers before treatment makes the financial side considerably more predictable.
How This Works With the Canadian Dental Care Plan
The Canadian Dental Care Plan (CDCP) does not simply follow the “basic versus major” labels used by many private insurance policies. Instead, it organizes eligible services into categories such as restorative, endodontic, periodontal, oral surgery and removable prosthodontic services, each with its own criteria, frequency limits and preauthorization requirements. The current Dental Benefits Guide took effect on April 1, 2026.
The CDCP covers many restorative services, including eligible fillings. Crowns can also be considered for eligible clients aged 18 and older, but they require preauthorization and must meet the plan’s clinical criteria. Removable complete and partial dentures are included under prosthodontic benefits, with preauthorization required in certain situations and frequency limitations applying.
Dental implants, implant-supported crowns and implant-supported dentures are not covered by the CDCP. Cosmetic procedures are also excluded when their primary purpose is aesthetic rather than treating oral disease or its consequences.
Patients using the plan should therefore confirm both eligibility and treatment-specific requirements before starting care. Lawrence Dental Centre accepts the CDCP in Scarborough and bills covered CDCP services directly through Sun Life.
Questions About Your Coverage?
Insurance wording can make a straightforward treatment plan unnecessarily confusing. Lawrence Dental Centre serves patients in Scarborough, accepts the CDCP, and offers direct billing to most major insurers, helping patients understand their benefits before treatment begins.
The team can provide a written treatment estimate and, when appropriate, submit a predetermination so you can see what your insurer is expected to reimburse before proceeding. Care is available in English and Farsi, making it easier to discuss both the clinical treatment and the financial details clearly.
Understand the Cost Before Treatment Begins
Lawrence Dental Centre can review your treatment needs, provide a written estimate and help you understand how your insurance or CDCP benefits may apply. With direct billing available at the Scarborough clinic, you can clarify expected coverage and possible out-of-pocket costs before moving forward with restorative dental work.
Conclusion
The difference between basic and major restorative dental work mainly matters because it can change how your insurance handles the cost. Fillings and many routine restorative procedures commonly fall under basic benefits, while crowns, bridges and dentures are more often classified as major work. Root canals are a good example of why checking your individual plan matters: their classification is not identical across every insurer.
Before starting treatment, confirm the procedure category, reimbursement percentage, remaining annual maximum, waiting period and predetermination requirements. For CDCP patients, use the plan’s own coverage and preauthorization rules rather than assuming private-insurance terminology applies.
FAQ
Dental insurance terminology varies between plans, so it is normal to be unsure whether a procedure is “basic” or “major.” These answers cover the most common questions patients have before restorative treatment.
What is the difference between basic and major restorative dental work?
Basic restorative work generally involves common procedures such as fillings and some extractions, while major restorative care typically includes more extensive treatments such as crowns, bridges and dentures. The exact classification depends on your dental insurance policy.
Is a root canal basic or major?
Many private dental plans classify root canal therapy as basic restorative or basic endodontic care, but some plans categorize it differently. Check your benefit booklet or ask your insurer about the specific treatment code before relying on a particular coverage level.
Is a crown considered major dental work?
Under many private dental insurance plans, yes—a crown is commonly treated as major restorative work. Under the CDCP, however, crowns are handled according to the plan’s own restorative-service rules and require preauthorization for eligible adults rather than simply being labelled “major.”
Does insurance cover major restorative work?
Many dental insurance plans provide some coverage for eligible major restorative procedures, but the reimbursement percentage, annual maximum, waiting periods and exclusions vary. A predetermination can help clarify expected reimbursement before treatment starts.
Does the CDCP cover crowns, dentures or implants?
Eligible crowns can be considered under the CDCP for adults aged 18 and older with preauthorization, and eligible removable partial and complete dentures are included under the plan’s prosthodontic benefits. Dental implants and implant-supported restorations are excluded.
Why is major dental work covered at a lower percentage?
Private insurers often design plans with different reimbursement levels for routine and higher-cost procedures. This helps control plan costs, but the percentages vary considerably, so there is no single coverage rate that applies to all Canadian dental plans.
What is a waiting period on dental insurance?
A waiting period is a set amount of time after your coverage begins during which certain services—often major restorative work—may not yet be eligible for reimbursement. Not every plan has one, so check your policy before scheduling treatment.
Have you ever been surprised to learn that your insurance classified a treatment as basic or major differently than you expected?
