Every dental practice principal knows the feeling. You arrive on a Monday morning, a full list ahead of you, and the autoclave isn’t working, or the compressor is throwing a fault mid-session when you need it the most. What happens next, and how much it affects the practice, is actually mostly dependent on decisions you made a long time before the breakdown occurred.
Equipment downtime is one of the most underestimated financial risks in dental practice, and one of the most preventable. Yet servicing is still a reactive consideration for many practices: call an engineer when something breaks and just absorb the cost of the disruption. In the current climate of rising overheads and tighter margins, as well as patients who expect a certain standard of efficiency, that approach is increasingly difficult to sustain.
The real cost of a breakdown?
When a piece of essential equipment fails, the immediate impact is visible: cancelled appointments and disrupted daily flow. But there can be more hidden costs than just these, plus an emergency call-out fee.
Lost appointment revenue is the most obvious figure. A single chair out of action for a day can result in hundreds of pounds in cancelled or rearranged appointments, as well as the fact that rescheduling is rarely seamless. If a patient cannot be seen promptly, they may look elsewhere for support. This may result in permanent loss of some of the patient list.
There are also compliance implications, as autoclaves and other disinfectors must be operating to certain specifications.[i] If equipment is out of service and records show a gap in the decontamination cycle, practices may find themselves answering difficult questions during their next inspection. There is a very real administrative burden when it comes to managing and evidencing remedial action during certain equipment failures, and this falls on a team that likely already has a full workload.
Then there is the element of reputational cost. In terms of patient experience, cancelling appointments and being, seemingly, unready for their arrival does not make a good impression – for private patients in particular. If they go to friends, family, or social media to complain, the practice risks even greater long-term harm.
Prevention vs reaction
Planned preventative maintenance is easy to advocate for, yet remains underutilised. A structured servicing programme that covers equipment including autoclaves, compressors, decontamination equipment and imaging systems will significantly reduce the likelihood of unplanned failure. It also means that when a component does reach end of life, it can be replaced on a planned basis rather than in a crisis.
Planned maintenance also supports compliance. Autoclaves require periodic validation under HTM 01-05.[ii] Compressors need regular servicing to maintain performance. Imaging equipment must be inspected and calibrated. Having a service provider who handles all of this on a scheduled basis, with documentation that stands up to all scrutiny, removes a significant administrative burden from the practice team.
This is even more clear to see when it comes to multi-surgery or multi-site practices. A single day of downtime across more than one site, with an emergency call-out fee, replacement parts, and days of rescheduled appointments, easily exceeds the annual cost of a comprehensive maintenance plan.[iii]
Choosing the right service partner
Not all servicing arrangements are equal. The key factors to consider are response time, full range of cover, and the engineering team’s familiarity with the equipment in your practice. A supplier with a large, regionally distributed engineering team can respond faster than one relying on a small pool of engineers covering wide geographic areas. Multi-skilled engineers trained across different equipment types offer much more flexibility when the issue is more complex than it initially appears.
It’s also worth considering whether your service provider can support you across the full range of equipment in your practice, or whether you are managing separate relationships with multiple suppliers. Consolidating servicing arrangements with a single trusted provider simplifies administration, reduces the number of contracts to manage, and typically improves response times.
Dental Directory operates one of the largest and most diverse engineering networks in UK dentistry, with multi-skilled engineers covering equipment testing, servicing, validation, and repair across a wide range of clinical and decontamination technologies. Practices can also access tailored service plans designed to match the scale and complexity of their setup – from single-surgery practices to multi-site groups – with clear documentation support built in.
Running a dental practice means accepting that things will occasionally go wrong. The best way to manage this, practically and realistically, is to have a plan of action set up in advance, and the right partner already in place.
