Does CDCP Cover Root Canals in 2026? Endo Coverage by Tooth Type

Last updated 2026-05-24. Fact-checked against Sun Life CDCP benefit grid -- endodontic category.

Yes -- CDCP covers root canal treatment across tooth types (anterior, bicuspid, molar) under the endodontic category. The federal fee schedule pays different amounts by tooth type because complexity scales with the number of canals. Anterior root canals usually don't require preauthorization; molar root canals typically do. Here's the breakdown and why some practices refer molars to endodontic specialists even when CDCP would cover in-house.

Key Takeaways

• Root canals are covered on all tooth types (anterior, bicuspid, molar) at the federal fee schedule.
• Anterior root canals: typically no preauthorization, federal fee ~$400-$550.
• Bicuspid root canals: sometimes preauthorization, federal fee ~$550-$700.
• Molar root canals: typically require preauthorization above a cost threshold, federal fee ~$700-$950.
• Re-treatment of a previous root canal: covered with preauthorization, higher fee.

Why root canal coverage varies by tooth type

Root canal complexity is largely determined by how many root canals (the tiny passages inside the root) the tooth has. The number scales roughly with tooth size and position:

Tooth type	Number of canals (typical)	Complexity	CDCP coverage
Incisors (front teeth)	1 canal	Lowest	Anterior endo, simpler
Canines	1 canal	Low	Anterior endo
Premolars (bicuspids)	1-2 canals	Medium	Mid-complexity endo
Molars (first/second)	3-4 canals	High	Molar endo, longer procedure
Wisdom teeth (3rd molars)	Variable, often complex	Variable	If preserved (rare)

The federal CDCP fee schedule reflects this complexity by paying progressively higher rates for more-complex endodontic treatment.

What you actually pay

Federal CDCP fee schedule (illustrative -- exact amounts depend on the specific code and current Sun Life benefit grid):

Root canal	Federal CDCP fee (typical)	Your share at 0% / 40% / 60%
Anterior (1 canal)	~$475	$0 / ~$190 / ~$285
Bicuspid (1-2 canals)	~$625	$0 / ~$250 / ~$375
Molar (3-4 canals)	~$825	$0 / ~$330 / ~$495
Re-treatment (molar)	~$1,000	$0 / ~$400 / ~$600

The follow-up restoration (filling or crown) is billed and covered separately. Molar root canals are typically followed by a crown to protect the weakened tooth; see Does CDCP Cover Crowns & Bridges?.

For broader cost worked examples, see the CDCP co-payment calculator.

Preauthorization: when it's required

• Anterior root canals: typically no preauthorization required. Your dentist can begin treatment after the diagnostic exam.
• Bicuspid root canals: preauthorization sometimes required (depends on the practice's submission threshold and case complexity).
• Molar root canals: typically require preauthorization above a cost threshold. The clinical justification (radiographic evidence of pulp involvement, periapical pathology, etc.) is submitted.
• Re-treatment of a previously root-canal-treated tooth: typically requires preauthorization regardless of tooth type.

Pre-determination turnaround is 7-21 days typically. For acute pain (irreversible pulpitis), your dentist may begin pulp removal to relieve pain immediately and complete the rest of the root canal once preauthorization processes.

Why some practices refer molars to endodontists

You might be told "your molar root canal would be better with an endodontist" even at a CDCP-participating practice. Three reasons that aren't about money:

1. Case complexity. Molars with 4+ canals, calcified canals, severe curvature, or previous failed treatment benefit from specialist tools and experience.
2. Time. A complex molar root canal can take 2-3 hours; many general practices don't block that much time in their schedules.
3. Specialty equipment. Endodontists use microscopes, advanced rotary instruments, and CBCT 3D imaging that many general practices don't have.

The endodontist must be CDCP-participating for direct billing. Check via the Sun Life provider search before the referral. Federal fee schedule is the same; the specialist's expertise and time are why your dentist refers.

What about re-treatment?

If you've had a root canal in the past on a tooth and it's failing (new infection, lingering symptoms, radiographic evidence), re-treatment is covered:

• Requires preauthorization
• Higher federal fee than initial treatment (more complex)
• May require referral to an endodontist
• Some failed root canals are better treated by apicoectomy (surgical root tip removal) instead of re-treatment; that's also covered under endodontic with preauthorization

From Dr. Kaur

"Root canals carry a reputation that doesn't match the modern experience. A well-anesthetized root canal feels like a long filling -- numb the whole time, no pain. The real anxiety is the cost, and CDCP largely resolves that at the 0% bracket. The conversation I have most often is around molars: 'do you want me to do this here, or should we refer you to an endodontist?' For straightforward molars I do them in-house. For complex anatomy I refer. Both pathways are CDCP-covered."

Frequently Asked Questions

Does CDCP cover root canals on all teeth? Yes, on all tooth types (anterior, bicuspid, molar). Federal fee schedule varies by tooth type to reflect complexity. Does my molar root canal need preauthorization? Typically yes, above the cost threshold. Your dentist submits clinical evidence; pre-determination usually returns in 7-21 days. Will I need a crown after my root canal? Anterior root-canal-treated teeth often don't require crowns; molars almost always do (because the weakened tooth structure is at high fracture risk). The crown is covered separately under major restorative; see Does CDCP Cover Crowns?. Can I get a root canal during the same visit as the exam? For acute pain, your dentist can begin pulp removal to relieve pain immediately. Completing the full root canal usually happens at a subsequent visit, especially for molars requiring preauthorization. Does CDCP cover endodontist visits? Yes, if the endodontist is a CDCP-participating provider. Check via the Sun Life provider search before the referral. Will CDCP cover re-treating a failed root canal? Yes, with preauthorization. Federal fee is higher than initial root canal treatment. Is sedation covered for root canal treatment? Yes, under the sedation category, with separate preauthorization. Most root canals are done with local anaesthesia only.

Bottom line

CDCP covers root canals on all tooth types at the federal fee schedule, with complexity-scaled rates (anterior ~$475, bicuspid ~$625, molar ~$825). Anterior typically no preauthorization; molar typically requires preauthorization. Re-treatment of a previous root canal is covered with preauthorization at a higher fee. A crown after a molar root canal is almost always recommended and is covered separately under major restorative. Specialists (endodontists) are an option for complex cases and must be CDCP-participating for direct billing.
