A four-operatory start needs about $645,000 before opening
Plan on $410,000 – $1.02 million to open a de novo general dental practice in Mississippi, with $645,000 as the Typical planning figure. The model is a dentist-owned professional corporation, one leased 2,400-square-foot site, four equipped operatories with plumbing for a fifth, and an owner-dentist providing restorative, preventive, diagnostic, limited endodontic and simple surgical care. It excludes orthodontics, IV sedation, a laboratory, and real-estate purchase.
The statewide Base case uses Mississippi wage data, a three-market occupancy planning basket, current state rules, and U.S. dental-practice benchmarks where no Mississippi series exists. At a stabilized $105,000 of monthly net collections, it produces about $25,800 of normalized passive-owner cash operating profit before D&A and about $43,300 of working-owner pre-tax business cash benefit. The pivotal caveat is ramp: payer credentialing, patient acquisition, build-out and collections timing can consume cash even when the stabilized practice looks attractive.
Configuration fingerprint: independent general dentistry; dentist-owned Mississippi professional corporation; one leased site; 2,400 square feet; four active operatories plus one plumbed shell; one owner-dentist, two assistants, one hygienist and 1.5 administrative FTE at stabilization; 16 clinical days monthly; mixed cash and commercial insurance. The canonical capacity is about 288 visits a month, not the number of appointment slots theoretically printed by software.
Dollar figures are 2026 planning dollars and exclude income taxes, debt principal and depreciation unless expressly stated. Dental services are not subject to Mississippi sales tax; the practice is the taxable consumer of equipment and supplies, according to the Department of Revenue's dentist fact sheet.
Capital plan
Build-out and liquidity – not the dental license – drive required cash
The Typical scope assumes a second-generation medical or office shell that still needs dental plumbing, electrical, shielding, cabinetry and infection-control improvements. Lean uses refurbished equipment and a lighter conversion; Premium uses five completed operatories, higher-spec imaging and a more difficult shell. The totals are project costs before financing. A lender commitment or landlord allowance reduces founder equity only when it is available in time to pay the corresponding invoice.
| Use of funds | Lean | Typical | Premium |
|---|---|---|---|
| Lease deposits, design and build-out | $112,000 | $205,000 | $362,000 |
| Dental equipment, imaging and sterilization | $145,000 | $218,000 | $348,000 |
| IT, furniture, phones and security | $25,000 | $39,000 | $58,000 |
| Entity, licenses, X-ray, legal and accounting | $9,000 | $14,000 | $22,000 |
| Insurance deposits and pre-opening payroll | $23,000 | $37,000 | $54,000 |
| Opening supplies and launch marketing | $26,000 | $39,000 | $58,000 |
| Initial net working capital | $14,000 | $22,000 | $31,000 |
| Operating-cash reserve | $44,000 | $112,000 | $67,000 |
| Contingency on uncertain hard costs | $12,000 | $29,000 | $20,000 |
| Total project cost | $410,000 | $715,000 | $1,020,000 |
| Documented landlord allowance | $0 | ($70,000) | $0 |
| Founder/lender funding required | $410,000 | $645,000 | $1,020,000 |
The $22,000 initial net working-capital line is receivables and prepaids less ordinary accrued liabilities; opening supplies are excluded because they are already listed. The $112,000 reserve is unrestricted cash sized to the modeled maximum cumulative ramp deficit plus a $35,000 closing-cash floor. A landlord reimbursement lowers ultimate funding but does not necessarily lower peak interim cash: the founder may still need roughly $715,000 available before reimbursement.
Critical path
Licensure, site design and payer setup must overlap
The owner must hold a current Mississippi dentist license before practicing. The Mississippi State Board of Dental Examiners regulates dentists, hygienists and radiology permit holders. A professional corporation rendering dentistry may issue shares only to licensed dentists; clinical judgment, fees and advertising remain under the licensed dentist's control under Board Regulation 55. The model therefore uses a dentist-owned professional corporation rather than mixing it with a general LLC.
Credential and form
Confirm dentist licensure route, form the professional corporation, obtain EIN, NPI, bank and accounting controls.
Control the address
Use a zoning and permit contingency before lease finalization; complete measured plans, equipment schedule and radiation shielding review.
Build and enroll
Run construction, utility coordination, commercial payer credentialing and Medicaid enrollment in parallel.
Inspect and open
Register X-ray units, finish occupancy/fire approvals, verify staff credentials, test systems and soft-open.
| Gate | Authority | Cost basis | Timing | Dependency |
|---|---|---|---|---|
| Professional corporation and EIN | Mississippi Secretary of State; IRS | Official filing fee; confirm current portal amount | Processing time not published | Before contracts, payroll and group payer enrollment |
| Dentist and hygienist licenses | MSBDE | Dentist by credentials $2,500; hygienist by credentials $750 under current Regulation 37 | Apply early; no SLA published | Before clinical work; verify current renewal cycle |
| Assistant radiology permits | MSBDE | $60 application in Regulation 37 | Seminar route must apply within 90 days of completion | Required before an assistant exposes radiographs |
| X-ray equipment registration | MSDH Radiological Health | Current fee schedule; local quote required for shielding | Agency SLA not published | Installed equipment data and Form 803 |
| Zoning, building, fire, occupancy, sign | City/county and fire authority | Varies by city/county | Modeled 8 – 24 weeks with construction | Address, plans, contractor and inspections |
| Payer and Medicaid enrollment | Commercial plans; Mississippi Medicaid | No state fee published; specialist help optional | Modeled 8 – 20 weeks; varies by payer | NPI, license, tax ID, ownership disclosures |
The state's X-ray Branch oversees registration and inspection of X-ray machines. Assistants may perform ordinary delegated assisting without a license, but must have a Mississippi radiology permit before exposing images; only a licensed dentist or dental hygienist may clean teeth, per the Board's auxiliary guidance.
Operating economics
Base collections require 238 visits – not a full four-chair schedule
The revenue unit is a completed patient visit. Base monthly collections equal 238 visits × $441 weighted net collections per visit = $104,958, rounded to $105,000. The $441 mix is 38% preventive/diagnostic visits at $185, 47% restorative visits at $520, and 15% higher-value endodontic, crown or surgical visits at $840. These are modeled net collections after contractual adjustments and refunds, not a fee schedule and not patient bills. Collected sales tax is excluded; Mississippi treats professional dental services as non-taxable.
| Driver or result | Downside | Base | Upside |
|---|---|---|---|
| Completed visits / month | 174 | 238 | 278 |
| Weighted net collections / visit | $414 | $441 | $460 |
| Monthly net collections | $72,000 | $105,000 | $127,880 |
| Variable non-owner cost | $17,280 | $23,100 | $27,494 |
| Owner clinical replacement labor | $12,240 | $17,500 | $20,781 |
| Fixed cash operating cost | $38,600 | $38,600 | $40,000 |
| Passive-owner cash operating profit | $3,880 | $25,800 | $39,605 |
| Working-owner pre-tax benefit | $16,120 | $43,300 | $60,386 |
| Maintenance capex reserve | $2,500 | $3,000 | $3,600 |
| Working-owner cash after maintenance capex | $13,620 | $40,300 | $56,786 |
The passive profit includes a market-value dentist replacement amount equal to 16.7% of collections in Base. That labor is variable because the dentist's production hours rise with visits. The working-owner view adds back only that already-deducted labor value; it is an imputed economic benefit, not salary or a guaranteed draw. The model does not fabricate D&A, so results are normalized cash operating profit before D&A.
Capacity ceiling
288 visits monthly assumes 18 visits per clinical day across hygiene and doctor schedules. Upside is 97% of modeled practical capacity and leaves little room for no-shows or equipment downtime.
Collections discipline
ADA guidance suggests monitoring a 98% collection rate against adjusted production. Aging over 90 days, claim denials and payer mix can make production look healthy while cash lags.
Patient pipeline
Base requires roughly 30 new patients monthly early in ramp, then relies on continuing care. Track kept hygiene appointments, unscheduled treatment value and referrals – not impressions or leads alone.
Cost control
Payroll and clinical inputs consume nearly half of Base collections
The Base staffing plan carries one hygienist, two assistants and 1.5 administrative FTE. Wage allowances are anchored to Mississippi occupational estimates and burdened 14% for employer payroll taxes, workers' compensation, unemployment and basic benefits; actual offers must be checked against the current labor pool. ADA practice guidance says total staff expense excluding dentists should generally remain around 23% – 26% of collections, while supplies often run 5% – 6% and first-year marketing 5% – 7%.
| Cost line | Monthly | % collections |
|---|---|---|
| Non-owner clinical and administrative payroll | $23,400 | 22.3% |
| Dental supplies and laboratory fees | $15,750 | 15.0% |
| Card fees and patient financing | $2,625 | 2.5% |
| Rent, CAM and utilities | $8,000 | 7.6% |
| Marketing | $5,250 | 5.0% |
| Insurance, software, compliance and phones | $5,600 | 5.3% |
| Repairs, waste, cleaning and professional fees | $3,750 | 3.6% |
| Bad debt and refunds | $1,050 | 1.0% |
| Owner clinical replacement labor | $17,500 | 16.7% |
| Total normalized cash operating cost | $82,925 | 79.0% |
This detailed cost view includes $17,500 of owner replacement labor. For scenario analysis, payroll is split between $20,400 of fixed staffing and $3,000 of visit-driven labor; the $38,600 fixed-cost line plus $23,100 of variable non-owner cost reconciles to the same Base economics. The resulting $25,800 passive profit before the $3,000 maintenance reserve and $40,300 working-owner cash after it are the decision values used throughout.
Unit economics
Each Base visit contributes $231 after economic dentist labor
The passive/economic visit starts at $441. Supplies and lab are $66; non-owner direct labor attributable to the visit is $55; card and financing cost is $11; bad debt/refunds are $4; and owner clinical replacement labor is $74. Passive contribution is therefore $231 per visit, or 52.4%. The working-owner cash contribution before owner compensation is $305 because it adds back only the $74 variable owner-labor amount already deducted.
| Measure | Result |
|---|---|
| Net collections per completed visit | $441 |
| Passive contribution per visit | $231 |
| Passive contribution margin | 52.4% |
| Cash-survival break-even before owner compensation | $51,500 / 117 visits |
| Sustainable working-owner break-even with $17,500 target | $76,900 / 174 visits |
| Passive-owner break-even | $68,700 / 156 visits |
| Debt-service break-even, illustrative $6,900 payment | $81,900 / 186 visits |
Cash-survival uses the $305 cash contribution before owner compensation and $35,600 of fixed non-owner cost. Sustainable working-owner break-even adds a $17,500 monthly target to that numerator. Passive break-even uses the matching $231 passive contribution and a $36,000 break-even fixed-cost band; no owner labor is counted twice. The illustrative debt-service case adds $6,900 plus $1,200 of recurring maintenance cash to the passive numerator. At 186 visits, debt-service break-even uses 65% of the 288-visit practical capacity.
Runway and return
The reserve protects a slow first year; payback remains execution-sensitive
The cash schedule begins with $112,000 of unrestricted reserve and a $35,000 minimum-cash floor. Collections ramp from $18,000 in month 1 to $72,000 in month 6, $95,000 in month 12 and $105,000 in month 15. Because receivables lag production and payer payments, the maximum cumulative operating deficit is about $77,000. The reserve stays above the floor in Base; a three-month credentialing delay or a $15,000 construction overrun would require a top-up unless offset elsewhere.
Monthly cumulative project cash after maintenance capex, using $645,000 net project funding and the full ramp.
Uses normalized market dentist labor and excludes financing and income tax.
The practice remains operating-positive but returns capital too slowly after maintenance.
These are unlevered project results: initial project capital is paired with project cash before financing. They are not founder-equity returns. If $500,000 were financed, equity payback would need a separate schedule with actual down payment, draw fees, rate, amortization and debt service. Do not divide $645,000 by a post-debt owner cash flow or treat unused reserve as a distribution.
Mississippi market test
Access gaps create opportunity, but not automatic demand
A reliable Mississippi dental-services market amount is not publicly determinable from available category data without mixing establishments, payer types and specialty revenue. Better demand proxies are the state's population, insured lives, dental-health shortage designations and local dentist density. The Mississippi State Department of Health identifies dental Health Professional Shortage Areas and publishes a statewide 2024 map; those designations show access constraints, not a guaranteed commercially viable patient panel.
Price × volume
A 5% fall in net collections per visit removes about $5,250 monthly at Base volume. Track payer fee schedules, write-offs and procedure mix by provider.
Labor × hygiene capacity
A vacant hygienist position cuts preventive capacity and downstream treatment. Track days-to-fill, hygiene reappointment and provider hours available.
Claims × cash lag
Ten extra days in accounts receivable ties up about $35,000 at Base collections. Track clean-claim rate, denial aging and days in A/R weekly.
For Medicaid participation, providers enroll through the MESA portal and recredential every three years. Commercial and public payer economics should be modeled separately before the lease: reimbursement, patient cost-sharing, authorization, claims friction and appointment availability can differ materially.
The address decision should therefore pass three tests: enough residents and employer coverage within a practical drive time; a competitor and referral map by specialty; and a schedule-level forecast proving that 30 new patients monthly plus continuing care can reach 174 visits by the sustainable working-owner break-even month. Shortage status alone does not prove willingness or ability to pay.
