Dental Practice Overhead: How to Track and Reduce Costs

A full diary does not guarantee a healthy clinic. Many dental practices are busy every day and still find that too little is left at the end of the month. The reason is usually not one big mistake but dental practice overhead that nobody looks at regularly: supplies ordered out of habit, lab costs that crept up, a lease signed years ago, software subscriptions nobody uses and chair hours that stand empty.

This guide shows how to see your costs clearly, which categories to track, how to calculate the cost of one chair hour and where savings are real rather than false. It deliberately avoids industry benchmark percentages: clinics differ too much by country, size and specialty for a single number to mean much. What matters is your own trend, month after month.

What counts as overhead in a dental practice

Overhead is everything it costs to keep the clinic open and running, as opposed to profit. To manage it, sort every cost into a small number of categories you use consistently. A practical set:

• Staff: salaries and contributions for assistants, hygienists, reception and management, plus training.
• Premises: rent or loan payments, service charges, cleaning and maintenance of the space.
• Clinical supplies: materials, disposables, anaesthetics, sterilization consumables.
• Laboratory: crowns, bridges, dentures, aligners and other lab work.
• Equipment: leases, loan repayments, servicing and repairs.
• Software and IT: practice software, imaging software, hardware, internet, phones.
• Marketing: website, advertising, printed material, sponsorships.
• Utilities and insurance: electricity, water, heating, professional and property insurance.
• Other: accounting, legal, bank fees, travel and anything that does not fit elsewhere.

How you treat the dentists' own pay depends on how the clinic is organised. Many owners track it separately so they can see what the clinic itself costs before clinical pay. Whatever you choose, apply it the same way every month.

Fixed and variable costs

Splitting costs into fixed and variable tells you where you have room to act.

Fixed costs

Rent, base salaries, equipment leases and most subscriptions stay roughly the same whether you see many patients or few. You lower them only through bigger decisions: renegotiating a lease, changing a contract, reorganising roles. The most effective way to make fixed costs lighter is usually to use the capacity you already pay for better, not to cut.

Variable costs

Materials, lab fees and some disposables rise and fall with the amount of treatment. Here the questions are different: are you paying a fair price, are you wasting material, and does each procedure's price cover its direct cost?

Calculate your cost per chair hour

The single most useful number for an owner is the cost of one chair hour. It connects overhead to the diary and to your prices.

1. Add up one month of fixed costs (staff excluding the dentists if you track them separately, premises, equipment, software, utilities, insurance, marketing).
2. Count the chair hours actually available that month: opening hours multiplied by the number of chairs in use, minus planned closures.
3. Divide costs by hours. The result is what every hour costs you before materials, lab fees and clinical pay.

For example, if a clinic's fixed costs in a month are 20,000 and it has 320 chair hours available, each hour costs 62.50 before anything else. If only 240 of those hours are used, each used hour actually carries about 83. That gap is often a bigger lever than any supplier discount, and it is why matching your rota to demand matters so much. The same number is the starting point for a sound dental fee schedule.

A monthly cost review routine

Overhead gets out of control between reviews, not during them. A short routine once a month is enough for most clinics.

1. Record every expense in the same week it happens, with category, clinic, supplier and the receipt attached.
2. Compare each category with the previous month and the same month last year. Look for changes, not for absolute numbers.
3. Check costs against production. Supplies and lab fees should move with treatment volume. If they grow faster, find out why.
4. Review subscriptions and contracts once a quarter: what renews soon, what is unused, what can be renegotiated.
5. Write down one or two actions, with an owner and a date, and check them next month.

If several people can spend money, add a simple approval step: expenses above an agreed amount are approved by the owner or practice manager before they are paid.

Where savings are real

Clinical supplies

Most supply waste comes from duplicate products, expired stock and emergency orders at full price. Standardise on fewer products per category, set reorder points, use the oldest stock first and order through purchase orders so you can compare prices over time. Our guide to dental inventory management covers this step by step.

Laboratory costs

Track lab costs per case and per lab, not just as a monthly total. Remakes are expensive for both sides, so record why they happen: impression quality, shade communication or lab error. Clear prescriptions and good photos often reduce remakes more than switching labs does.

Staff time

Staff is usually the largest cost, and cutting hours is rarely the answer. Look instead at where time is lost: manual reminder calls, double data entry, searching for paper records, reworking invoices. Every hour removed from low-value work is an hour available for patients.

Empty chair time

No-shows, late cancellations and gaps in the schedule turn fixed costs into pure loss. Reminders, a short-notice list and a clear cancellation policy, described in our article on reducing no-shows, protect the hours you already pay for.

False savings to avoid

Some cuts look good on a spreadsheet and cost more later. Be careful with:

• Infection control and sterilization. Never economise on these. The risks to patients and to the clinic are far greater than the savings.
• Equipment maintenance. Skipping service visits saves money until a compressor or autoclave fails on a full day.
• Cheaper materials with higher failure rates. A restoration that has to be redone free of charge costs more than the material you saved.
• Training. A team that knows the software and the procedures works faster and makes fewer costly mistakes.
• Understaffing. Running permanently short leads to burnout and turnover, and recruiting and onboarding are expensive.

A simple monthly overhead dashboard

You do not need a complex report. One page, reviewed monthly, with these lines is enough to steer:

• Total expenses by category, this month versus last month and last year.
• Production and collections for the same period.
• Supplies and lab costs as a share of production, tracked as your own trend.
• Cost per available chair hour and chair utilization.
• No-show and late cancellation rate.
• Expenses per clinic, if you run more than one location.

Overhead control checklist

• Every cost belongs to one of a small set of categories, used consistently.
• Expenses are recorded weekly with receipts attached.
• Larger expenses go through a simple approval step.
• You know your cost per chair hour and update it every quarter.
• Supplies are ordered through purchase orders with reorder points.
• Lab costs and remakes are tracked per case and per lab.
• Subscriptions and contracts are reviewed every quarter.
• One or two cost actions are agreed each month and followed up.

Frequently asked questions

What is a normal overhead level for a dental practice?

Published benchmarks vary widely by country, practice size, specialty and how dentists' pay is counted, so a single figure is easy to misread. It is more useful to track your own costs by category every month and act on the trend. Your accountant can help you compare with similar practices in your market.

How often should we review expenses?

Record expenses weekly and review them once a month. Contracts, leases and subscriptions deserve a closer look every quarter and before each renewal date.

What is the fastest way to reduce overhead?

Usually it is using existing capacity better rather than cutting: fewer no-shows, fewer gaps in the schedule and less time lost to manual admin. After that, supplies and lab costs are the areas where clinics most often find waste.

Should each clinic in a group track its own costs?

Yes. Record each expense against the clinic it belongs to, and keep shared costs such as central management in a separate group line. That way you can compare locations fairly.

Key takeaways

• Sort every cost into a few consistent categories and record expenses weekly.
• Calculate your cost per chair hour and use it for scheduling and pricing.
• Review costs monthly against production, and contracts quarterly.
• Look for waste in supplies, lab work, admin time and empty chair hours.
• Never save on infection control, maintenance or training.
