The single most common reason dentists stay in unprofitable insurance contracts is not financial ignorance — it is fear. Fear that the moment they terminate a carrier, the waiting room empties. That fear is understandable, but it is also largely unsupported by what actually happens when practices make this transition thoughtfully.
Research from the Dental Success Institute and Dental Intelligence, cited by Gary Takacs of the Thriving Dentist — who has coached more than 2,200 practices through PPO transitions — shows that 60 to 80 percent of patients will stay with their dentist after leaving an insurance network. Takacs' own practice, LifeSmiles, retained over 85 percent of its patient base after dropping all PPO plans. His stated goal for any practice he coaches: retain between 85 and 95 percent of existing patients through the transition.
That is not a guarantee. It is a benchmark — and it is achievable when the transition is managed correctly. The practices that lose 30 or 40 percent of patients are almost always the ones that handled the communication poorly, moved too fast, or dropped carriers without replacing the revenue channel.
Why Patients Leave — and Why Most Do Not
When a dentist drops a carrier, patients face a real cost increase. If they stay, they pay the difference between the dentist's fee and whatever their out-of-network benefit covers. For some patients, that difference is meaningful. For others, it is not.
The patients most likely to leave are those who chose the practice specifically because it was in-network — patients who found the practice through their insurance directory and have no other relationship with the provider. These are often newer patients with lower case acceptance and lower lifetime value. The patients most likely to stay are those who have been with the practice for years, trust the dentist personally, and chose the practice for reasons beyond the insurance benefit.
This distinction matters because it reframes the question. The question is not "how many patients will I lose?" The question is "which patients will I lose, and what is their actual value to the practice?"
ACT Dental's Kirk Behrendt frames this directly: "The first step to moving away from PPOs is to get rid of the limiting belief that patients will only see you because you're on their insurance plan. Your patients come to see you because you're valuable. They come because of you." The practices that internalize this — and communicate from that position — consistently outperform the ones that approach the transition apologetically.
The Six Factors That Determine Your Retention Rate
Not all practices will retain 85 percent. The actual outcome depends on six variables that consultants consistently identify as the primary drivers:
| Factor | Higher Retention | Lower Retention |
|---|---|---|
| Patient tenure | Long-term patients (3+ years) | Newer patients acquired via insurance directory |
| Communication lead time | 60–90 days advance notice | Short or no notice |
| Communication quality | Personal, value-focused, multi-touch | Form letter, single notice |
| Alternative payment options | In-house membership plan, financing | No alternatives offered |
| Marketing investment | Active new patient acquisition running | Referral-only, no active marketing |
| Carrier selection | Dropping one carrier at a time | Dropping multiple carriers simultaneously |
The last point is worth emphasizing. Benjamin Tuinei of Veritas Dental Resources, who has helped over 9,000 dentists navigate insurance transitions, recommends terminating one carrier at a time — starting with the lowest-performing one — rather than making a wholesale exit. This approach limits the pool of affected patients at any given moment and gives the practice time to absorb and replace the revenue before the next termination.
The Communication Protocol That Retains Patients
The practices with the highest retention rates share a consistent communication approach. It is not a script — ACT Dental explicitly cautions against scripts, noting that what works in one practice culture may not work in another — but it follows a clear structure.
Step 1: Notify 60–90 days in advance. Patients need time to make decisions. A letter or email that arrives two weeks before the effective date feels like a surprise. One that arrives three months out feels like a courtesy. The longer lead time also gives patients time to schedule any outstanding treatment before the change takes effect, which increases production in the transition period.
Step 2: Lead with the relationship, not the insurance. The communication should open with the value the practice provides — the quality of care, the relationship, the team — before it mentions insurance at all. Practices that open with "we are no longer in-network with your plan" immediately frame the conversation as a loss. Practices that open with "we are committed to providing you with the best possible care, and we want to tell you about a change" frame it as information.
Step 3: Be specific about what it means for them. Patients do not understand insurance terminology. They need to know: will they still be able to come to this practice? Will their insurance still pay anything? What will it cost them? The communication should answer all three questions directly, without jargon.
Step 4: Offer a path forward. This is where alternative payment options become critical. A practice that says "we are leaving your network, but here is our in-house membership plan that gives you a discount on all services and no annual maximum" gives the patient a reason to stay. A practice that says "we are leaving your network, you can still come but you will pay more" gives the patient a reason to find a new dentist.
Step 5: Follow up personally for high-value patients. For patients who have been with the practice for five or more years, or who have significant outstanding treatment plans, a personal phone call from the front desk — or in some cases the dentist — dramatically increases retention. This is not scalable for every patient, but it is worth the time for the top 20 percent.
The Marketing Offset: Replacing What You Lose
Even a well-managed transition with 85 percent retention means losing 15 percent of the patient base. For a practice with 1,200 active patients, that is 180 people. The practices that come out ahead are the ones that have a plan to replace those patients — ideally before the transition is complete.
This is where most dentists are most exposed. As you noted, many dental practices do not market at all. They run on referrals, word of mouth, and insurance directory listings. When the insurance directory listing disappears, so does one of their primary patient acquisition channels — and they have nothing to replace it.
The consultants who specialize in this transition — Gary Takacs, Kirk Behrendt at ACT Dental, Naren Arulrajah at Ekwa Marketing — consistently make the same point: the marketing strategy should be in place before the carrier termination takes effect, not after. The practices that struggle are the ones that drop a carrier, lose patients, and then start thinking about marketing. The practices that succeed are the ones that build their new patient pipeline first, then make the carrier change.
The channels that work best for replacing insurance-dependent new patients are:
Google Search (paid and organic): Patients who are searching for a dentist without an insurance filter are higher-value patients. They are not choosing based on network participation — they are choosing based on quality, convenience, and reputation. A practice that ranks well for "dentist near me" or "best dentist in [city]" captures patients who are predisposed to pay for quality.
Google Business Profile: Reviews are the most powerful trust signal for new dental patients. A practice with 200 five-star reviews will attract patients who are not on any insurance plan. Actively soliciting reviews from existing patients — especially during the transition period when those patients are reaffirming their loyalty — is one of the highest-ROI activities a practice can do.
In-house membership plans: Platforms like BoomCloud and Membersy allow practices to create their own subscription dental plans — typically $25–$40/month — that include two cleanings, x-rays, and a discount on all other services. These plans serve two purposes: they give existing patients who lose their insurance benefit a reason to stay, and they attract uninsured patients who would otherwise not seek care. Practices that launch a membership plan alongside a carrier termination consistently report higher retention than those that do not.
Referral activation: Existing patients are the most credible source of new patients. A practice that is actively asking satisfied patients for referrals — and making it easy to refer — can offset a significant portion of the new patient loss from a carrier termination. This is particularly effective during the transition period, when patients who choose to stay are demonstrating the highest level of loyalty.
What the Numbers Actually Look Like
To make this concrete, consider a practice with the following profile:
- 1,200 active patients
- 40 percent of patients on the carrier being dropped (480 patients)
- Average annual revenue per patient: $800
- Current write-off rate on that carrier: 32 percent
At 85 percent retention, the practice loses approximately 72 patients from that carrier (480 × 15%). Revenue lost: approximately $57,600 per year.
But the revenue picture changes when you account for the write-off elimination. Those 408 patients who stay are now paying full fee. If the practice was writing off 32 percent on that carrier, the revenue per retained patient increases from approximately $544 (after write-offs) to $800 — an increase of $256 per patient per year. Across 408 retained patients, that is $104,448 in recovered revenue annually.
Net result: the practice loses $57,600 in patient revenue but recovers $104,448 in write-offs — a net gain of approximately $46,848 per year, before any new patient acquisition.
This is the math that most dentists have never seen laid out clearly. The fear of patient loss is real, but the financial reality — when the transition is managed well — almost always favors the move.
The igion.ai Connection
The carrier analysis that igion.ai produces is the starting point for this entire process. Before a practice can make a confident decision about which carrier to drop first, they need to know which one is costing them the most — not just in write-offs, but in operational friction, revenue concentration risk, and net reimbursement relative to the rest of their mix.
The KEEP / MONITOR / RECONSIDER framework is designed to answer exactly that question. A carrier in the RECONSIDER category is the natural starting point for a transition conversation. The scorecard gives the practice the data to make that decision with confidence, and the renegotiation toolkit gives them the leverage to try to fix the contract before terminating it.
The patient retention strategy described in this article is what happens after that decision is made. The data comes first. The transition plan follows.
Key Takeaways
Research from the Dental Success Institute and Dental Intelligence shows that 60–80 percent of patients typically stay when a dentist leaves an insurance network. With deliberate communication and a replacement marketing strategy in place, leading consultants report retention rates of 85–95 percent. The practices that lose the most patients are those that move without a plan. The practices that come out ahead are those that treat the carrier termination as a business transition — with the same preparation and communication they would give any other major practice change.
The fear is understandable. The data suggests it is manageable.
