Dental Practice Line of Credit: When Revolving Credit Beats an MCA (2026)

Dental practices have a cash-flow shape that almost no other small business shares. Production is steady — the chairs are full, the schedule is booked weeks out — but collections arrive on somebody else's timetable. Insurance reimbursements land 30 to 60 days after the work is done. Meanwhile payroll hits every two weeks, the lab bills monthly, and the supply rep shows up whether or not Delta Dental has paid last month's claims. The practice is profitable on paper and tight on cash in the checking account, every single month.

That pattern is exactly what revolving credit was designed for. A dental practice line of credit gives you a standing facility you draw against when collections lag and repay when they catch up — and you only pay for what you use. This guide covers how dental lines of credit actually work, what dentists draw them for, the honest cost math against a merchant cash advance, and what funders look at before they approve your file.

How a dental practice line of credit actually works

A line of credit is not a loan — it is access to money. The lender approves you for a limit, say $50,000. You draw $20,000 to cover payroll during a slow insurance month. You pay interest only on the $20,000, not the $50,000. As you repay, the available credit replenishes, and you can draw again next quarter when the next gap appears. No new application, no new underwriting, no waiting.

Three mechanics matter. First, draws are on demand — most dental credit lines let you pull funds to your business checking account within a day or two, some same-day. Second, repayment is usually weekly or monthly on the outstanding balance, and many lines let you pay interest-only during the draw period. Third, the line typically renews annually — the lender re-checks your financials once a year and renews the facility, often with a higher limit if the practice grew.

Qualification looks like this in practice: most dental line-of-credit lenders want at least 12 months in business, roughly $100,000+ in annual practice revenue, a personal credit score in the 600s or better, and clean bank statements. Stronger files — two-plus years, $500,000+ in collections, 680+ credit — unlock bigger limits and lower rates. Practices that do not clear those bars yet usually start with a merchant cash advance and graduate to a line of credit once the statements look better.

What dentists actually draw it for

The payroll bridge. The most common draw in dentistry. Two payrolls land while the big insurance checks are still in transit. A $15,000 draw covers the gap; it is repaid when reimbursements clear. This is a timing problem, not a profitability problem, and revolving credit is the correct tool for timing problems.

Lab and supply bills. Crown, bridge, and implant lab work bills on 30-day terms while the patient's insurance pays on 45-to-60-day terms. Supply orders — composite, anesthetic, disposables — do not wait. A standing line smooths the mismatch without a second thought.

Slow months and seasonality. December is dead in many practices (patients max out benefits in November, then disappear for the holidays). Summer dips when families travel. A line of credit turns a seasonal dip into a non-event instead of a crisis.

Emergency equipment repairs. A compressor or vacuum pump failure is a same-day problem — no suction, no dentistry. If the practice already has a line open, the repair is a draw, not a financing application under pressure.

The new-associate ramp. Hiring an associate means paying a guaranteed salary for months before their production covers it. A line of credit funds the ramp without touching the owner's distributions.

Line of credit vs. MCA vs. term loan

The three products answer different questions. Here is the honest map:

The rule of thumb: recurring need → line of credit; one-time need → term loan; emergency or bruised credit → MCA. Financing a $150,000 CBCT with a line of credit you never pay down is a misuse; covering twelve payroll gaps a year with twelve MCAs is financial self-harm.

The honest cost math

Take a $40,000 draw — a typical payroll-bridge size for a mid-size practice — and run it through two products.

Line of credit: $40,000 at an illustrative 15% annual rate, repaid over 12 months. The monthly payment is about $3,610 — roughly $43,324 in total repayment, or about $3,324 in interest. Repay it in 6 months instead of 12 and the interest drops to roughly $1,750, because you only pay for the time you hold the money. (Illustrative; your rate depends on credit, revenue, and the lender.)

Merchant cash advance: $40,000 at a 1.35 factor rate. The payback is $54,000 — $14,000 in cost, locked in on day one, repaid through daily or weekly debits regardless of how fast you could have repaid. There is no early-payoff discount on the factor cost with most MCA funders.

Same $40,000. One costs $3,324, the other $14,000. That is not a trick of the example — it is the structural difference between paying for time and paying a fixed factor. The MCA's advantage is speed and accessibility, not price, and it should be used like it.

What funders check on a dental file

Collections, not production. Funders underwrite what hits the bank account. A practice producing $120,000 a month but collecting $85,000 gets underwritten on the $85,000 — and the gap between the two is itself a data point.

Statement health. Consistent deposits, no chronic overdrafts, no unexplained large transfers out. Dental practices have an advantage here: insurance and card deposits are regular and documentable, which is exactly what underwriters want to see.

Time in business and credit. Twelve months minimum for most line-of-credit products; two-plus years unlocks the best terms. Personal credit in the 600s clears most alternative-lender bars; 680+ opens bank-grade options.

Existing debt load. A practice already carrying two MCAs with daily debits will struggle to get a line of credit — the debits eat the cash flow the line would rely on. This is the most common reason dental line-of-credit applications get declined, and it is fixable: pay down or consolidate the stacked advances first, then apply.

When an MCA still wins

Intellectual honesty requires the other side. A line of credit takes days to underwrite and fund the first time — if the compressor died this morning and patients are booked this afternoon, 24-hour MCA money is the right call, and you refinance it into proper facilities later. Practices under a year old or with sub-600 credit usually cannot get a line of credit at all; an MCA funds on revenue, not credit history. And some owners simply prefer the MCA's automatic repayment — no monthly decision to make, the debit just happens.

The discipline is sequencing: MCA for the emergency, line of credit for the pattern. Practices that reverse the order — MCAs for recurring gaps — end up in the debt spiral our MCA debt guide was written to address.

Mistakes that cost dentists real money

Treating the line like a term loan. Drawing the full limit and making minimum payments for a year turns revolving credit into expensive permanent debt. Draw for the gap, repay on collections, keep the line mostly available.

Applying while stacked with MCAs. Daily debits destroy the cash-flow picture a line-of-credit underwriter needs to see. Clear or consolidate first — then the line gets approved at a limit worth having.

Waiting for the crisis to apply. A line of credit opened in a calm month funds draws in a day or two. A line applied for during a crisis takes a week you do not have. Open it before you need it; that is the entire point of revolving credit.
