Dental Hygienist Called in Sick? Here's What to Do | Airlocum

By Eugene Bojé, BChD, MBA, MSc — Founder of Airlocum

It's 7:15 AM. Your hygienist has just sent a message — she's not coming in. You've got a full hygiene list starting at 9 AM, patients who've waited weeks for their appointments, and a practice that runs on a razor-thin schedule. Now what?

A hygienist cancellation is one of the more disruptive staffing emergencies a dental practice manager can face. Unlike a receptionist or even a dental nurse, a locum hygienist is harder to source at short notice, carries specific GDC registration requirements, and sees patients independently. You can't just cover the session with whoever's available.

This guide walks you through exactly what to do — in the right order — so you can minimise disruption, keep patients informed, and build a more resilient system before this happens again.

Why a Hygienist Absence Hits Harder Than Other Roles

Dental nurses can sometimes be redistributed across surgeries. A receptionist absence creates pressure, not paralysis. But when your hygienist calls in sick, you're looking at an entire hygiene list — typically six to eight patients — that cannot proceed without a qualified replacement.

A dental hygienist absence typically costs UK practices £500+ in net lost revenue per day. Cancel those appointments and you lose the revenue, consume staff time rebooking patients, and risk losing patients who can't wait. According to NHS dental statistics, 8–12% of rescheduled dental patients fail to rebook within 90 days — that's lost lifetime value, not just one missed appointment.

There's also a compliance angle. The CQC expects dental practices to maintain continuity of care, and hygiene patients often have specific clinical needs — active periodontal disease, recall protocols, ongoing treatment plans. Cancelling and rescheduling doesn't just inconvenience them; it can interrupt care pathways your practice is clinically responsible for.

The First 15 Minutes: Act Before You Call Patients

Don't call patients first. That's the instinct, but it's the wrong move. Spend the first 15 minutes trying to find cover. If you secure a locum, many of those appointments can still go ahead.

Step 1: Check Your Existing Locum Contacts

If you've used a locum hygienist before, start there. A locum who already knows your practice is always the fastest option — no induction, no familiarisation time.

If you're an Airlocum practice, open the app and check your Favourites list. Use Quick Book to send the shift directly to hygienists who've worked at your surgery before. Practices with an established Favourites list fill same-day gaps in an average of under 15 minutes.

Step 2: Post a Shift on a Locum Platform Immediately

The faster you post, the more options you have. Locum hygienists checking availability at 8 AM will take bookings quickly — hesitate and they'll accept another practice's request.

On Airlocum, shift requests are sent instantly to every verified locum hygienist in your area. Hygienists have a 50% same-day booking rate on the platform. The service fee for hygienists averages approximately £40 per day, compared to £80–100 per booking through a traditional staffing agency — and hygienist bookings on Airlocum carry no mileage charges.

Step 3: Triage Your List While You Wait

While your request goes out, look at your hygiene list and identify which appointments are clinically most urgent. Patients with active periodontal disease, those mid-treatment, or those who've already been rescheduled once should be prioritised. If you can only save three appointments from a full day, having this triage ready means you can act the moment a locum confirms.

Your Four Options for Same-Day Hygienist Cover in 2026

When you need a hygienist at short notice, you have four main routes. Here's an honest assessment of each.

Your Existing Network — Fastest, Least Reliable

Texting hygienists you've worked with before is the first move — but unless you maintain a warm list of locums who know your practice, this often draws blanks at short notice. Worth trying, but don't spend more than 10 minutes on it before moving to a more systematic option.

Traditional Staffing Agency — Slow, Expensive

Agencies can source locum hygienists, but they typically take 30–60 minutes to confirm cover and charge £80–100 per booking. For a same-day emergency, they're rarely the fastest option — and at that fee level, you're spending 10–15% of the day's hygiene revenue just on the placement.

Social Media and WhatsApp Groups — Inconsistent

Posting in local dental Facebook groups or WhatsApp communities sometimes works, but it's unreliable. You have no way to verify GDC registration or check reviews in advance — and under GDC regulations, all dental professionals must hold valid registration to practise.

A Locum Staffing Platform — Fastest for Verified, Rated Cover

Airlocum connects practices directly with GDC-verified locum professionals. You can see ratings, reliability scores, and previous reviews before anyone confirms. Every locum's GDC registration is verified automatically every 28 days. Hygienist bookings carry no mileage charges, unlike some other roles.

What to Tell Your Patients (And When)

Once you know whether you have cover, communicate with patients clearly.

If you've found cover, contact any patients affected by the short delay. Let them know the appointment is going ahead with a different hygienist. Most patients understand — they just want to know their appointment is safe.

If you haven't found cover, start contacting patients as soon as you're confident cover isn't coming. Prioritise patients with the most urgent clinical needs, then work through the list by appointment time. Give a realistic rescheduling window — don't promise dates you can't keep.

Keep your message simple: "We have a staff absence today and unfortunately your appointment needs to be rescheduled. We've made a note of your treatment plan and will ensure continuity of care when you come back in." That's enough.

What a Locum Hygienist Needs to Work at Your Practice

Before a locum arrives, make sure you have these basics ready.

GDC registration

Under GDC regulations, any locum working as a dental hygienist must hold valid GDC registration. On Airlocum, GDC verification is automated every 28 days and confirmed before any locum appears in search results.

Indemnity

Locum hygienists working as self-employed contractors should hold their own professional indemnity cover. Confirm this before the session.

Scope of work

Your locum needs to know what the day involves — periodontal reviews, standard recalls, or anything more complex. Have your nurse brief them on arrival, and flag anything that falls outside standard hygiene work.

Patient notes

Ensure records are accessible. A good locum hygienist will ask to review notes before each patient. Give them five minutes per patient to do this properly — it's time well spent for quality of care.

How to Avoid This Crisis Next Time

One last-minute hygienist cancellation is bad luck. Two in six months is a systems problem. Here's how to build resilience.

Build a shortlist before you need it

The best time to find a locum is when you don't need one urgently. After any session that goes well, save that locum's profile on Airlocum. Build a shortlist of two or three hygienists who know your practice, your systems, and your patient mix.

Use 'My Favourites First' on Airlocum

When you post a shift, your saved locums are contacted ahead of the general pool. If your regular locum is available, they'll see and accept your request before anyone else does.

Post shifts further ahead when possible

Same-day requests fill quickly, but posting even 24 hours ahead meaningfully improves your options and increases the chance of getting a locum who already knows your practice.

Prepare your patient communication templates now

Nobody wants to write a cancellation message at 7:15 AM. Draft two templates — one for "appointment going ahead with cover," one for "appointment needs rescheduling" — and save them somewhere accessible. Thirty seconds of preparation saves significant stress on the day.

The Bottom Line

A hygienist calling in sick feels catastrophic in the moment and manageable in retrospect. The difference usually comes down to two things: how quickly you can source verified cover, and whether you have a system already in place.

Airlocum gives you access to verified, GDC-checked locum hygienists across the UK — with no mileage charges and a flat service fee of approximately £40 per day. Rated 4.9 out of 5 on Google from 90 reviews, and trusted by corporate groups including Bupa, MyDentist, Rodericks, and Portman Dentex.
