Dental clinics: buying a job, or buying a business

30 September 2026

One chair is a job with good pay. Four chairs is a business someone will buy. The gap between them is the only thing worth studying.

Dentistry is the most reliably profitable trade a non-specialist can buy, and the most reliably misunderstood. The mistake is always the same: the buyer models a clinic as a business and then operates it as a job, because at the size most people can afford, it is one.

A one-chair practice is a dentist with a mortgage. A four-chair practice is a business with dentists in it.

The revenue engine

Everything is chairs multiplied by utilisation. A chair is a fixed asset that can produce about seven patient slots a day, twenty days a month, at an average ticket that depends entirely on the mix between routine work and implants.

revenue = chairs × days × patients × ticket
Average ticket, not price list. Mix is the lever.

At 3.0 chairs running 7.0 patients a day at an average of €190, the clinic bills €79,800 a month. The number that moves this most is not volume — it is ticket, and ticket is a function of how much implant and orthodontic work you take rather than how busy you are.

This is a business. The margin survives paying someone else to do the clinical work.

Set the associate share to zero and the margin looks wonderful. That is the trap: a zero associate share means you are in the chair, and the moment you price your own labour honestly, the business is barely profitable. Drag it to 40% and you are looking at what the clinic is actually worth to a buyer who is not a dentist.
