Acquiring an existing dental practice is the most common path to practice ownership for dentists entering private practice — and for good reason. An established practice delivers a patient base, trained staff, functional equipment, and existing cash flow from day one. But the acquisition is also a complex transaction with legal, financial, clinical, and regulatory threads that must all close at the same time. A Gantt chart is what keeps those threads synchronized.

The typical dental practice acquisition runs 3–6 months from letter of intent (LOI) to closing. For a dentist managing a busy associateship while simultaneously managing an acquisition, the project management overhead is significant. This guide maps every major phase of a dental practice acquisition Gantt with realistic timelines and the dependencies that most buyers miss.

Why Dental Acquisitions Need a Gantt Chart

The single most common scheduling failure in dental practice acquisitions is delayed insurance credentialing. Credentialing with dental payers — Delta Dental, MetLife, Cigna, United Concordia, Guardian — under the buyer's NPI and Tax ID typically takes 60–90 days. If the buyer does not start credentialing at or before LOI signing, there will be a gap between closing and the ability to bill in-network claims. In a practice where 60–70% of revenue is insurance-driven, a 90-day credentialing gap translates directly to cash flow crisis.

A Gantt chart makes this timeline visible and forces the credentialing workstream to start at the correct point — not at closing.

Phase 1 — Practice Identification and LOI (Weeks 1–6)

Practice brokers and deal sourcing: Most practices are listed through dental practice brokers (ADS Transitions, Professional Practice Sales, Omni Practice Group, Henry Schein Dental Practice Transitions are major networks). A qualified buyer who works with a broker has access to the listing data but should also network directly with retiring dentists through study clubs and state dental associations — off-market deals are common in dentistry.

Initial assessment: Before spending significant time on due diligence, conduct a quick financial screen:

Annual collections (top-line revenue)
Overhead percentage (target: under 60–65% for a healthy general practice)
Patient count and active patient base (patients seen in past 18 months)
Collection per visit (a marker of procedure mix and case acceptance)
Number of operatories (capacity constraint for growth)

Valuation: Dental practices are typically valued at 60–80% of annual collections for a general dentistry practice in most markets. Specialty practices command higher multiples: orthodontics 80–100%, oral surgery 100–130% of collections. Three valuation methods may be applied:

Revenue multiplier: Most commonly used for dental acquisitions
EBITDA multiple: 5–7x EBITDA for dental is typical; requires normalization of the owner's compensation
Excess earnings method: Identifies the earnings above a fair market return on tangible assets — the intangible (goodwill) value is then capitalized

Letter of intent (LOI): The LOI establishes price, structure (asset sale vs. stock sale — asset sales are far more common in dental acquisitions), and exclusivity period for due diligence. Asset sales allow the buyer to step up the tax basis of acquired assets; stock sales transfer the entity and its liabilities.

Gantt anchor: LOI signed Week 4. Exclusivity period begins. Due diligence starts immediately.

Phase 2 — Due Diligence (Weeks 4–12)

Due diligence for a dental practice acquisition is both financial and clinical. Both tracks should run in parallel.

Financial due diligence — documents to request:

3 years of tax returns (corporate and personal if sole proprietor)
3 years of profit and loss statements
Most recent 12 months of practice management software production reports
Accounts receivable aging report (current: under 30 days; watch for high percentage over 90 days — indicates collection issues or insurance billing problems)
12 months of bank statements
Payroll records and staff compensation schedules
Lease (remaining term, renewal options, assignability)
Equipment list with purchase dates and condition

Production reports — the clinical due diligence layer: Request production reports by procedure code (ADA CDT code). This analysis reveals:

Procedure mix: Is the practice hygiene-heavy (preventive care only) or does it produce significant restorative, endodontic, implant, or oral surgery? Higher-value procedures indicate a practice with established case acceptance.
Per-provider production: Is the practice heavily dependent on the selling dentist's personal production? If the seller produces 85% of collections and is leaving immediately, patient attrition risk is significant.
Patient retention and recall rate: Hygiene recall percentage (patients reappointed within 6 months of prior hygiene visit) indicates practice health. Under 60% is a red flag.

Active patient count: "Active patients" in dental is typically defined as patients seen within the last 18 months. Verify this number directly from the practice management software, not from the seller's summary — and run a vintage analysis (how many patients have been active for 5+ years vs. new patients in the last 12 months).

Equipment assessment: Hire a dental equipment technician to inspect the major equipment: dental chairs, delivery units, X-ray systems (are they digital or film?), CBCT/3D imaging if present, compressor and vacuum systems, sterilization equipment. Equipment condition directly affects your capital expenditure needs in years 1–3.

Lease review: The lease is often overlooked until late in due diligence. A lease with 2 years remaining and no renewal option — or one with a landlord who has not consented to assignment — can kill or restructure an otherwise attractive acquisition. Review the lease at Week 4, not Week 10.

Gantt anchor: Financial documents received Week 5. CPA review complete Week 9. Equipment inspection Week 7. Lease review complete Week 8. Due diligence findings delivered to buyer Week 10.

Phase 3 — Financing (Weeks 4–14)

Most dental practice acquisitions are financed with an SBA 7(a) loan — the SBA program with the most favorable terms for dental practice acquisitions:

Loan amount: Up to $5M
Repayment term: 10 years for business acquisition (up to 25 years for real estate)
Collateral: Limited or no collateral required for acquisitions within the SBA's size standards
Equity injection: Typically 10% equity from the buyer

Lender selection: Healthcare-focused lenders have dedicated dental lending programs with faster approval timelines and more favorable underwriting for practice acquisitions:

Live Oak Bank: Largest SBA dental lender nationally
Wells Fargo Healthcare Finance: Dedicated healthcare lending division
BMO Healthcare: Strong dental practice loan portfolio
Bankers Healthcare Group (BHG): Conventional (non-SBA) dental loans with faster funding but higher rates

SBA process timeline: Pre-qualification (1–2 weeks) → full application with practice financials and personal financial statement → underwriting (2–3 weeks) → SBA loan number issuance → closing (1–2 weeks). Total: 6–10 weeks from application to funding.

Apply for financing at LOI or immediately after. Do not wait until due diligence is complete — the financing and due diligence tracks should run in parallel. Waiting sequentially adds 6 weeks to the closing timeline.

Gantt anchor: Lender pre-qualification submitted Week 4. Formal application submitted Week 6. Loan commitment letter Week 10. Loan closes concurrently with practice acquisition Week 14–16.

Phase 4 — Insurance Credentialing (Weeks 4–18 — Starts at LOI)

This is the most time-sensitive workstream and the one most commonly started too late.

The credentialing reality: Credentialing a new dentist with dental payers under a new NPI and Tax ID (or under the same Tax ID with the buyer added to the group) takes 60–90 days per payer. Some payers (Medicaid dental, certain managed care plans) can take 120 days.

Payers to credential with:

Delta Dental (multiple regional plans — check which plan covers your geographic area)
MetLife
Cigna Dental
United Concordia
Guardian
Aetna Dental
Any state Medicaid dental plan if the practice accepts Medicaid

Action steps:

Verify the buyer has an active NPI (National Provider Identifier) — apply at NPPES if not
Request the selling dentist's current fee schedules, EOBs (Explanations of Benefits), and provider IDs from each payer
Submit credentialing applications to each payer — include the closing date as the "effective date" even if it is estimated
Follow up with each payer weekly — credentialing coordinators are responsive to persistent follow-up

Credentialing management: Managing 8–12 simultaneous payer credentialing applications while also managing due diligence is unmanageable for most buyers. Hire a dental credentialing specialist or a dental management company for this workstream. Cost: $500–$1,500 for the full credentialing project — trivial compared to the revenue impact of a 60-day credentialing gap.

Gantt anchor: Credentialing applications submitted Week 4–5 (immediately at LOI). First payer confirmations received Week 12–14. All major payers credentialed by closing Week 16–18.

Phase 5 — Transition Planning (Weeks 10–20)

Seller transition period: The seller typically continues working in the practice for 3–6 months after closing to introduce the new dentist to patients. This is the single most important factor in patient retention. The seller should introduce the buyer to as many patients as possible during their hygiene appointments and in scheduled transition letters. Patient retention in a well-managed transition: 85–95%. Patient retention in an abrupt transition: 60–75%.

Transition letter to patients: Draft a letter from the seller to the patient base announcing the transition and introducing the new dentist — warm, personal, specific to the practice's history. Mail this letter 2–4 weeks before closing. Email the active patient database the same week.

Staff retention: The team is the practice. Patients form relationships with hygienists, dental assistants, and front office coordinators — not just with the dentist. Meet individually with each staff member before closing. Understand their concerns. Consider retention bonuses for key staff members tied to 90-day and 180-day milestones.

State dental board notification: Most states require notification to the state dental board when a dental practice changes ownership. In some states, the practice entity must apply for a new dental facility permit. Verify your state's requirements — penalties for operating without the required registration can include practice suspension.

Gantt anchor: Staff meetings Week 12. Patient transition letter drafted and approved Week 14. Seller introduces buyer at hygiene appointments ongoing from Week 12. State dental board notification submitted Week 14.

Phase 6 — Post-Acquisition Integration (Weeks 16–28)

Practice management software: Most practices run Dentrix, Eaglesoft, or Open Dental. The buyer faces a choice: migrate to their preferred software, or continue with the existing system. Continuation is strongly preferred for the first 6–12 months — migration disrupts clinical workflow and risks data loss at exactly the moment when patient retention is most fragile. Plan any software migration for 12+ months post-close.

Google Business Profile: Update the name, hours, phone number, and practitioner information on Google Business Profile immediately at closing. This is the most visible signal to patients that the practice is operational under new ownership.

Insurance fee schedule review: New insurance contracts are an opportunity to renegotiate fee schedules. Request a fee schedule review with each payer at 6 months post-credentialing.

Associate hiring: If the seller is departing immediately and the practice volume requires it, recruit an associate dentist before closing. Associate recruitment takes 60–90 days.

A dental practice acquisition Gantt with insurance credentialing starting at LOI, financing running in parallel with due diligence, and transition planning overlapping with closing is the difference between a smooth ownership handoff and a 90-day revenue gap that strains both the buyer's cash flow and the seller's earnout.
