How to Decide Which Dental Insurance Plans to Keep or Drop at Your Practice in 2026

More than one-third of dental practices surveyed by the American Dental Association in late 2025 said they plan to drop at least some insurance networks in 2026. In Ontario, the decision is even more complex: CDCP participation, ODA fee guide gaps, and the rise of direct billing are forcing practice owners to rethink their entire insurance strategy. As of September 2026, this is no longer a theoretical exercise — it is a financial imperative.

As of September 2026, dental insurance dynamics in Canada are shifting faster than at any point in the past decade. The Canadian Dental Care Plan has added a new government payer to the mix, provincial fee guide adjustments have not kept pace with rising practice costs, and patient expectations around direct billing have created administrative pressure that many practices absorb without measuring its true cost. The question is no longer whether to review your insurance participation — it is how to make that decision systematically rather than reactively.

This guide provides a framework for evaluating which insurance plans to keep, which to renegotiate, and which to drop — grounded in the financial realities that Ontario dental practices face right now.

Why Insurance Strategy Matters More in 2026 Than Ever Before

The economics of dental insurance participation have fundamentally changed. Three forces are converging to make the keep-or-drop decision urgent:

Force 1: The Wage-Reimbursement Gap

Staff wages — particularly for dental hygienists — have risen sharply over the past three years. In the Greater Toronto Area, experienced hygienist compensation has climbed 15-25% since 2023, driven by workforce shortages that show no sign of resolving. Meanwhile, most private insurance plans base their reimbursement on fee guides that adjust by 2-4% annually. The math is simple: your costs are rising at three to five times the rate of your reimbursement. Every year you delay addressing this gap, the problem compounds.

Force 2: CDCP Adds Volume at Government Rates

The Canadian Dental Care Plan has brought millions of previously uninsured Canadians into the dental system. For practices that opted in, CDCP has delivered patient volume — but at fee schedules that are often 15-30% below the ODA suggested fee guide. This is not a criticism of the program; it is a mathematical reality that practice owners must account for when calculating their blended reimbursement rate across all payers.

Force 3: Administrative Cost Is Invisible but Real

Every insurance plan your practice participates in carries administrative overhead: claims submission, predeterminations, appeals for denied claims, coordination of benefits, and patient communication when coverage falls short of the billed amount. Most practices do not track this administrative cost per plan. When they do, the results are often surprising — some plans cost more to administer than the margin they generate.

Step 1: Calculate Your Cost Per Chair Hour

Before you can evaluate any insurance plan, you need to know what it costs to operate each chair in your practice for one hour. This is your breakeven number — the minimum revenue per hour that a plan must generate to avoid losing money on every appointment.

The Calculation

Start with your total annual practice overhead (everything except doctor compensation): staff wages, rent, supplies, lab fees, equipment, insurance, marketing, administrative costs. Divide by the total number of chair hours available annually across all operatories.

For example, a four-operatory practice with $720,000 CAD in annual overhead, operating 48 weeks per year with each operatory available 32 hours per week:

Total chair hours: 4 operatories × 32 hours × 48 weeks = 6,144 chair hours per year

Cost per chair hour: $720,000 ÷ 6,144 = $117.19 CAD per chair hour

That means every hour of chair time must generate at least $117.19 CAD in net collections just to cover overhead — before the dentist takes home a single dollar. Any insurance plan that reimburses below this threshold is losing money on a per-appointment basis, regardless of how many patients it sends you.

Pro Tip: Run this calculation using your actual numbers from your last fiscal year. Most practice management software can generate a report of total collections and chair utilization. If your overhead percentage is above 65%, your cost per chair hour is almost certainly higher than you expect — and more insurance plans are below your breakeven than you realize.

Step 2: Map Each Insurance Plan's Net Reimbursement

Once you know your cost per chair hour, evaluate each insurance plan you participate in. For each plan, calculate:

1. Gross reimbursement per typical appointment: What does the plan pay for a standard unit of service (exam, cleaning, single-surface composite, crown)?
2. Administrative cost per claim: Estimate the staff time spent on predeterminations, claims submission, follow-ups, and patient communication for that plan. Multiply by your administrative staff hourly rate.
3. Net reimbursement: Gross reimbursement minus administrative cost.
4. Net reimbursement per chair hour: Divide by the average appointment duration for that plan's typical procedures.

What You Will Likely Find

Most practices that complete this exercise discover a Pareto pattern: approximately 20% of their insurance plans generate 80% of their insurance-based revenue at acceptable margins. Another 30-40% of plans are marginally profitable. And 20-30% of plans are operating below breakeven — meaning the practice loses money on every appointment with patients from those plans.

The unprofitable plans often share common characteristics: they are older group plans with fee schedules that have not been updated in years, they have complex predetermination requirements that consume disproportionate administrative time, or they have high denial rates that require appeals and resubmissions.

Step 3: Assess Patient Volume and Retention Risk

Dropping an insurance plan is straightforward financially but complex operationally. Before making the decision, quantify the patient impact:

• How many active patients use this plan? Pull a report from your practice management software showing unique patients who billed through each plan in the past 12 months.
• What percentage of your total active patients does this represent? If a plan covers fewer than 5% of your active patients, dropping it has minimal retention risk. If it covers more than 15%, the financial impact of patient attrition requires careful modelling.
• What is the patient's loyalty anchor? Patients who chose your practice for location, reputation, or a specific clinician are less likely to leave over an insurance change than patients who chose you primarily because you accepted their plan.

Pro Tip: Before dropping any plan that covers more than 10% of your active patients, send a direct communication explaining the change and offering a 90-day transition period. Patients who value your practice relationship will often continue as fee-for-service patients or switch to an accepted plan during their next employer enrollment period. The attrition rate on well-communicated plan departures is typically 30-40% — meaning 60-70% of patients stay.

Step 4: The CDCP Calculation — A Special Case

The Canadian Dental Care Plan deserves its own analysis because it operates differently from private insurance plans. CDCP fee schedules are set by the federal government and are not negotiable at the practice level. The reimbursement rates are generally pegged to a percentage of the provincial fee guide, often covering 80-90% of the guide rate for basic services but significantly less for major procedures.

When CDCP Participation Makes Financial Sense

• Your practice has unused chair capacity: If you have open appointment slots, CDCP patients fill them at a positive contribution margin (even if below your preferred rate). Marginal revenue above variable cost is still revenue.
• Your practice serves a community with high CDCP eligibility: In some GTA neighbourhoods, CDCP-eligible patients represent a significant portion of the local population. Refusing to participate may mean losing access to a large patient pool.
• You focus on preventive and basic services: CDCP reimbursement for exams, cleanings, and simple restorations is closer to the ODA fee guide than for major procedures. If your practice mix is heavily weighted toward these services, the reimbursement gap is smaller.

When CDCP Participation Creates Financial Strain

• Your practice is already at capacity: If every chair hour is booked, accepting CDCP patients at below-guide rates displaces higher-reimbursement appointments. You are effectively choosing lower revenue per hour.
• Your practice mix is procedure-heavy: For practices with significant prosthodontic, implant, or complex restorative caseloads, CDCP reimbursement for these procedures may fall well below cost of delivery.
• Administrative burden is disproportionate: CDCP preauthorization processing times have stretched past 30 days in some cases. The administrative cost of managing delayed authorizations and patient communication can erode the already-thin margins on CDCP procedures.

Step 5: Renegotiation Before Termination

For insurance plans that fall below your breakeven threshold but represent significant patient volume (more than 10% of active patients), renegotiation should precede termination. Not all insurance companies will negotiate, but many will — particularly when they risk losing a network provider in a market where dental access is already constrained.

What to Negotiate

• Fee schedule updates: Request a fee schedule review based on current market rates. Provide the ODA suggested fee guide as a benchmark and demonstrate the gap between their current reimbursement and your cost of delivery.
• Administrative simplification: Request electronic claims submission, reduced predetermination requirements, or faster claims processing timelines. Administrative cost reduction can sometimes close the profitability gap even if fee schedules do not change.
• Specialty carve-outs: If the plan underpays for specialty procedures but is acceptable for basic services, propose a tiered arrangement where basic services are billed at the plan rate and major procedures are billed to the patient at the fee guide rate.

Step 6: Implementing the Transition

Once you have decided which plans to keep, renegotiate, or drop, the implementation process matters as much as the decision itself. A poorly communicated plan departure can damage patient relationships and generate negative reviews that cost more than the savings from dropping the plan.

Communication Timeline

1. 90 days before: Send a letter (physical mail, not just email) to all affected patients explaining the change, the reason (focus on "continuing to provide the quality of care you expect"), and their options.
2. 60 days before: Follow up with an email and a phone call from your front desk team to patients with scheduled appointments in the transition period.
3. 30 days before: Post the change on your website and social media channels. Update your Google Business Profile to remove the plan from your accepted insurance list.
4. Day of change: Ensure your front desk team has a script for handling incoming calls from patients who did not receive or read the notifications.

Pro Tip: Frame the communication around care quality, not cost. Patients respond poorly to "we cannot afford to accept your insurance" but respond well to "we want to continue providing you with the time and attention your dental care deserves, and to do that, we need to make changes to our insurance participation." The message is the same; the framing makes the difference.

The Fee-for-Service Opportunity

Every insurance plan you drop creates potential for fee-for-service conversion. Patients who stay with your practice after a plan departure become fee-for-service patients — and fee-for-service patients are, on average, the most profitable segment of any dental practice. They pay at your full fee guide rate, they have no predetermination delays, and they tend to accept treatment recommendations at higher rates because they are making an active choice to invest in their dental health.

The transition from an insurance-dependent practice model to a blended insurance/fee-for-service model is one of the most impactful financial decisions a practice owner can make. It requires courage, careful communication, and a willingness to accept short-term patient volume dips in exchange for long-term financial health.

Building Your Insurance Strategy Dashboard

Insurance strategy is not a one-time decision — it is an ongoing operational discipline. Build a quarterly review process that tracks:

• Net reimbursement per chair hour by plan: Update this quarterly as fee schedules change and your overhead evolves.
• Patient volume by plan: Monitor for shifts in your payer mix that could indicate market changes.
• Administrative cost per claim by plan: Track the time your team spends on each plan's claims and predeterminations.
• Attrition rate by plan: After dropping a plan, measure how many affected patients stayed versus left. This data informs future decisions.

The practices that thrive in 2026 and beyond are those that treat their insurance participation as a strategic portfolio — actively managed, regularly reviewed, and aligned with the practice's financial objectives. Passive participation in every available plan is not a strategy. It is a default that costs your practice money every day.

Frequently Asked Questions

Q: Can a dental practice in Ontario legally refuse to accept a patient's insurance plan?

Yes. The Royal College of Dental Surgeons of Ontario (RCDSO) does not require dentists to participate in any specific insurance network. Dentists are free to accept or decline participation in any private insurance plan. However, the RCDSO does require that patient care decisions are not influenced by insurance status — you cannot refuse to treat a patient in an emergency based on their insurance coverage. For non-emergency care, participation in insurance networks is a business decision, not a regulatory obligation.

Q: How do I calculate whether a dental insurance plan is profitable for my practice?

Calculate your practice's cost per chair hour by dividing total annual overhead by total available chair hours. Then calculate the net reimbursement per chair hour for each insurance plan (gross reimbursement minus administrative cost, divided by average appointment duration). If the net reimbursement per chair hour is below your cost per chair hour, the plan is operating at a loss. A practice with $720,000 CAD in annual overhead across four operatories operating 32 hours per week for 48 weeks has a cost per chair hour of approximately $117 CAD.

Q: What percentage of patients typically leave when a dental practice drops their insurance plan?

With proper communication (90-day advance notice, direct outreach, and clear value messaging), patient attrition from a dropped insurance plan typically ranges from 30% to 40%. This means 60-70% of affected patients choose to stay with the practice as fee-for-service patients or switch to an accepted plan during their next enrollment period. Practices that communicate poorly or provide insufficient notice may experience higher attrition rates.
