Most dental practice owners track production and collections, but few know which specific procedures actually make money after overhead is factored in. Per-procedure profitability analysis reveals which services drive your margins and which quietly drain them — giving you the data to make smarter scheduling, staffing, and fee decisions in 2026.
As of June 2026, dental practice overhead in Canada continues to climb at roughly 5% annually. Supply costs, labour expenses, lab fees, and technology investments all compete for a share of every dollar collected. Yet most practice owners make scheduling and capacity decisions based on production volume rather than actual profitability. A procedure that generates $1,200 in production but costs $1,100 in chair time, materials, and labour to deliver is not a growth driver — it is a margin trap.
Per-procedure profitability analysis changes how you think about your schedule. Instead of asking "How much did we produce today?" you start asking "How much did we actually keep?"
What Per-Procedure Profitability Actually Measures
Production tells you what you billed. Collections tell you what you received. Per-procedure profitability tells you what remained after you subtract the direct and allocated costs of delivering that specific service.
The calculation has three components:
- Revenue per procedure: The actual collected amount (not the billed amount), adjusted for insurance write-offs, CDCP fee schedule differences, and patient copay shortfalls
- Direct costs: Materials consumed, lab fees, and any procedure-specific supplies
- Allocated overhead: Chair time multiplied by your per-minute overhead rate, which includes staff wages, facility costs, equipment depreciation, and administrative burden for that operatory
The result is your true profit margin per procedure — the number that should inform your strategic decisions.
Pro Tip: Calculate your per-minute operatory cost by dividing total monthly overhead (rent, utilities, staff wages, insurance, supplies, technology) by the total number of clinical minutes available across all operatories. For most Ontario practices in 2026, this figure falls between $8.00 and $14.00 CAD per minute.
How to Calculate Your Per-Minute Overhead Rate
This single number is the foundation of every profitability calculation. Here is a straightforward method for a typical Ontario general practice:
Step 1: Total Your Monthly Fixed and Semi-Variable Costs
Include rent or mortgage, utilities, staff salaries and benefits, practice management software, equipment leases and depreciation, malpractice insurance (CDSPI premiums), RCDSO registration fees (prorated monthly), general supplies, and administrative costs. For a solo practitioner in the Greater Toronto Area with two operatories, this figure typically ranges from $45,000 to $75,000 CAD per month in 2026.
Step 2: Calculate Total Available Clinical Minutes
Multiply the number of operatories by clinical hours per day by working days per month by 60 minutes. For example: 2 operatories × 7.5 hours × 20 days × 60 minutes = 18,000 clinical minutes per month.
Step 3: Divide
If monthly overhead is $60,000 CAD and available clinical minutes are 18,000, your per-minute operatory cost is $3.33 CAD. But operatories are rarely running at 100% utilization. At a realistic 75% utilization rate, the effective per-minute cost rises to $4.44 CAD. Add the dentist's time value (what you need to earn per minute to meet your income target), and the fully loaded per-minute rate typically lands between $8.00 and $14.00 CAD.
Running the Numbers: Which Procedures Actually Pay?
Once you have your per-minute rate, you can evaluate any procedure. Here are examples using typical Ontario fee ranges and overhead assumptions for a practice with a $10.00 CAD per-minute fully loaded rate:
Procedure Example 1: Single Crown (Porcelain-Fused-to-Zirconia)
- Collected revenue: $1,350 CAD (private insurance patient, ODA fee guide)
- Lab fee: $280 CAD
- Materials (impression, temporary, cement): $45 CAD
- Chair time (two appointments, prep + seat): 90 minutes total
- Overhead allocation: 90 × $10.00 = $900 CAD
- Net profit: $1,350 − $280 − $45 − $900 = $125 CAD (9.3% margin)
Procedure Example 2: Composite Filling (Two-Surface)
- Collected revenue: $285 CAD
- Materials: $18 CAD
- Chair time: 30 minutes
- Overhead allocation: 30 × $10.00 = $300 CAD
- Net profit: $285 − $18 − $300 = −$33 CAD (−11.6% margin)
Procedure Example 3: Hygiene Recall (Scale, Polish, Exam)
- Collected revenue: $310 CAD
- Materials: $12 CAD
- Chair time: 50 minutes (hygienist appointment + doctor exam)
- Overhead allocation: 50 × $10.00 = $500 CAD
- Net profit: $310 − $12 − $500 = −$202 CAD (−65% margin)
Wait — does that mean hygiene recalls lose money? Not necessarily. The overhead allocation above uses the fully loaded dentist-operatory rate, but hygienist labour costs are lower. If you calculate a separate per-minute rate for hygiene operatories (which typically have lower overhead), the picture changes. More importantly, hygiene appointments are the primary driver of restorative case detection and patient retention. Their value is strategic, not purely transactional.
The point is not that you should stop doing hygiene or fillings. The point is that you need to know which procedures subsidize which, so you can make informed decisions about scheduling mix, fee adjustments, and capacity allocation.
Pro Tip: Build a simple spreadsheet with your top 15 procedures ranked by frequency. For each one, calculate collected revenue, direct costs, chair time, and overhead allocation. Update it quarterly. Most practice owners who do this exercise for the first time discover at least two or three services where they are consistently losing money.
Five Actions to Improve Per-Procedure Profitability
1. Reduce Chair Time Without Cutting Corners
Chair time is the largest variable in per-procedure profitability. Investing in workflow efficiency — better tray setups, digital impressions that eliminate remakes, and structured appointment templates — directly improves margins. A crown prep that takes 45 minutes instead of 60 saves $150 CAD in overhead at a $10/minute rate.
2. Review Your Fee Schedule Against the ODA Guide
The Ontario Dental Association (ODA) 2026 Suggested Fee Guide provides a benchmark, but many practices have not adjusted fees in years. If your fees for specific procedures have not kept pace with rising overhead, those procedures may have shifted from profitable to break-even or worse. Review your top 20 procedures against the current ODA guide annually.
3. Audit Insurance Write-Offs by Procedure
Some insurance plans reimburse well for certain procedure categories and poorly for others. If you are writing off 30% on crowns but only 10% on periodontal scaling, that difference dramatically affects relative profitability. Track write-off percentages by procedure code, not just in aggregate. For CDCP patients, compare the federal fee schedule against your actual costs for each service delivered.
4. Optimize Your Scheduling Mix
Once you know which procedures generate the strongest margins, you can structure your schedule to prioritize them during peak hours. This does not mean refusing lower-margin procedures — it means being intentional about how many high-margin versus low-margin appointments fill your day. A schedule packed with low-margin procedures at high volume can produce impressive production numbers while generating mediocre take-home income.
5. Separate Hygiene and Restorative Overhead Calculations
Running a single blended overhead rate across the entire practice masks the true economics of your hygiene department versus your restorative operatories. Calculate separate per-minute rates for each. Many practices discover that their hygiene department is a strong profit centre when measured independently — but the insight is invisible without separate tracking.
Why This Matters More in 2026
The Canadian dental market surpassed $20 billion in 2026, but that growth is not distributed evenly. Practices facing CDCP fee schedule reimbursements below the ODA suggested amounts, rising material costs driven partly by ongoing tariff pressures on imported supplies, and escalating staff compensation demands need granular financial visibility to protect their margins. Aggregate KPIs like monthly production and collection percentages are necessary but insufficient. Per-procedure profitability gives you the resolution to identify exactly where money is being made and where it is being lost.
Frequently Asked Questions
Q: How often should I run a per-procedure profitability analysis?
Quarterly is the practical minimum. Material costs, insurance reimbursement rates, and staffing expenses all shift throughout the year. A quarterly review catches margin erosion before it compounds. Many practice management software platforms can automate the data collection, but the analysis itself — deciding what to do about the numbers — requires the practice owner's judgment.
Q: Should I stop offering procedures that show negative margins?
Not automatically. Some procedures with thin or negative direct margins serve strategic purposes: hygiene appointments drive case detection, emergency exams build patient loyalty, and simple restorations keep the schedule full between higher-margin cases. The goal is awareness, not elimination. Know which procedures subsidize which, and make deliberate choices about your service mix.
Q: Does per-procedure profitability change for CDCP patients versus privately insured patients?
Yes, often significantly. CDCP fee schedule reimbursements for many procedures sit below the Ontario Dental Association (ODA) suggested amounts. Running the profitability calculation separately for CDCP-reimbursed procedures versus privately insured procedures reveals where the gap is largest, and helps you manage your patient mix and scheduling accordingly.
