Why Dentists Run Late: 17 time sucks that can destroy your schedule

Dentists don’t commonly run late because they’re slow. They run late because their systems, habits, and workflows create choke points.

Running late in dentistry is like quicksand. Once you get drawn in you keep sinking deeper and deeper. One moment you’re prepping a molar, and before you blink, you’re thirty minutes behind, your nurse is tight‑lipped, and your next patient is at the reception desk asking: “How much longer?”.

I learned a lot about running on time from the most efficient dentist I’ve ever seen, one of my mentors, Dr Omer Reed from Phoenix. Omer never kept anyone waiting and yet he delivered enormous amounts of excellent dentistry. He didn’t rush. He simply worked in a way that was efficient.

Once, I watched him prepare two premolars for gold onlays. I thought he was just getting started but he had already finished. It was like watching a concert pianist whose hands move so rapidly you can’t see the technique, only the result.

Omer taught me a simple truth: running on time is respect for the patient, the team, the craft of dentistry, and yourself.

Here are seventeen time sucks that push dentists behind schedule and what to do about them.

1. Starting the appointment before everything is ready

The appointment begins when the dentist walks into the operatory.

If the instruments aren’t set, if the lab work is not on the tray, if the nurse is off doing something else, or if your head is still in the previous appointment, you’ve already lost time. It’s like starting a music concert before the band has set up. Would Taylor Swift step on stage if the band wasn’t ready? Of course not. She only comes out when everything is ready to go. Efficient dentists do the same.

Ten minutes before the appointment, the room is ready, the instruments are in sequence, and the nurse knows the opening move. When you walk in, it’s all systems go.

The sure-fire way to know the operatory is not set properly is if your nurse needs to leave the room or call out for missing items during the procedure. If that keeps happening you should tighten up your setup procedures.

2. Underestimating how long procedures actually take

Many dentists schedule based on best-ever scenarios rather than typical ones.

A Class II that can, if everything runs absolutely perfectly, take 28 minutes should not be scheduled as a thirty‑minute appointment. You should schedule to your average and include a few minutes as a buffer. Don’t forget to allow for everything the procedure requires — anaesthetic, isolation, matrix placement, adjustments, notes, and room turnover.

If you schedule to your best-ever timing as opposed to the average with a small buffer, the result is predictable. The day starts on time and slowly drifts off course. On-time dentists schedule based on actual averages, not hope.

3. Too much chit‑chat

Warmth matters, but too much small talk is like too much sugar in tea — it ruins the balance.

Years ago, I ran an experiment. For one month, I did zero chit‑chat, other than, “Hello, my name is Dr Hassed. Thanks for coming,” everything else was strictly about the dentistry. Guess what. The patients didn’t miss it. No one complained and my treatment acceptance rate was the same.

That experiment taught me something important: patients come to the dentist to get their teeth fixed, not for conversation. Efficient dentists keep chit-chat brief.

One of the best dentists I know at making patients feel comfortable never chats more than 20-30 seconds and only while getting the patient ready for treatment. He talks with such warmth and focus that the patients admire his wonderful chair-side manner.

4. Leaving the room mid‑procedure

This is one of the biggest time sucks in dentistry.

Dentists leave the room to check hygiene, answer a question, look at a lab case, or, quite commonly, to start another patient. In theory it sounds efficient — “Look at me, I’m multi-tasking.” In reality, it destroys momentum.

Every departure means de-gloving, re‑gloving, and rebuilding focus. It’s like stopping halfway through a marathon to browse the shops. You can finish the race, but not on time.

Patients notice too. They sit there wondering why you keep disappearing. They feel abandoned and unimportant.

My simple rule was once I sat down, I’m super‑glued to the seat until the procedure is finished. That mindset forces you to commit, stay present, and design your workflow so everything you need is already in the room.

5. Allowing patients to add things at the last minute

A patient says, “While I’m here, can you have a quick look at this tooth?” or “A tooth on the other side is sore. Can you fix that as well?” or “My teeth need a clean. Can you do it today?” Some dentists say yes out of kindness.

But it’s impossible to conjure time out of thin air. A “quick look” rarely turns out to be quick. It normally requires x-rays or other diagnostic tests. It disrupts the flow of the appointment, steals minutes you don’t have, and pushes the day behind schedule.

When my patients tried to add an extra treatment on top of the one they booked for I found honesty was the best approach. I would say: “I’ve only got enough time to fix one problem today. You pick which one.” My schedule stayed intact.

6. Doing too much of the work yourself

Some dentists behave as if they’re the only licensed human in the building.

They adjust the light, hold the suction, get their own instruments, and type their own notes. It’s the clinical equivalent of a surgeon trying to operate while also answering the phone.

The real cost isn’t just time — it’s also focus. Every time you hunt for an instrument, shift your eyes, or break your rhythm, you drain mental energy. By the end of the day, you’re worn out not from the dentistry, but from the interruptions.

This is why I wrote an entire article on 6‑handed dentistry. When done properly, it’s not a luxury — it’s essential. A well-trained nurse will anticipate the next step, the next instrument, the next movement allowing the dentist to stay in the zone. The procedure becomes a smooth choreography instead of a scavenger hunt.

7. Having too many materials and too many choices

A cluttered menu of materials slows everything down.

When you have five different bonding agents, six different composites, four different impression materials, and drawers full of “just in case” products, every decision takes longer. Choice creates delay. There’s a great book on the topic called The Paradox of Choice by Barry Schwartz.

I’ve heard dentists saying: “Let’s use OptiBond… no, on second thoughts G‑Bond…, no, Clearfil SE…” Meanwhile the nurse is sitting there wondering why everything needs to be so complicated.

Nurses should know exactly what bonding material you use for every procedure. These decisions should be made once and then baked into your routine. For a Class II filling, I used a particular bond 100% of the time. For a porcelain onlay, I used a different bond 100% of the time. Doing that removes the improvisation and guesswork.

Efficient dentists don’t have more materials. They have fewer — and they use them consistently.

8. Spending too much time typing instead of delegating

One of the saddest sights in dentistry is a dentist spending their lunch break typing notes.

Lunch should be a reset, not a punishment. When you burn your only long break doing admin, the afternoon always feels heavy. I try to avoid touching the computer altogether. Not because I consider myself above it, but because I understand the cost.

Every minute spent typing is a minute you’re not resting, thinking, or recovering. On-time dentists delegate documentation. The nurse or AI enters the notes, and the dentist verifies at the end.

Templates, shortcuts, and structured phrasing keep the process efficient. Your attention should be on dentistry, not data entry.

9. Fixing problems that should never have happened

Redo work is a thief of time.

A high spot, a rough margin, a contact that needs adjusting — each of these steals minutes from your future schedule. But the most common and most damaging is the open contact point. An open contact that packs food is bad news. The patient returns frustrated, uncomfortable, and expecting a fix. And now you’re re‑doing work you already did for free.

Post‑operative sensitivity is another big one. A tooth that zings every time the patient bites is a guaranteed time‑suck. Simply telling the patient that teeth are often sensitive after a filling or crown will reduce follow up visits.

Make sure to slow down at the right moments. Check margins, occlusion, and contacts with care. Floss every contact. Find a bonding protocol that eliminates sensitivity. Thirty seconds of precision can prevent thirty minutes of correction and sometimes thirty days of patient frustration.

10. Not respecting the patient’s time as much as your own

Most lateness isn’t intentional, but sometimes it is.

I knew a dentist who deliberately kept patients waiting because it made him feel in demand. He believed it reinforced his status and importance. In reality, it simply made him difficult to respect. Dentists need to realise that patients’ time is just as important as their own. If they are a company executive their hourly rate may well be higher than yours.

Patients notice when you run late. Some don’t mind but many find it irritating. They become less cooperative and harder to work with. If you keep doing it, quite a few will leave the practice which is a sad way to churn and burn patients.

Contrast that with Omer Reed — the most efficient dentist I’ve ever seen — who never kept anyone waiting. His punctuality was about respect. Patients trusted him instantly because he respected their time as much as his own.

11. Talking on the telephone during clinical time

Nothing breaks the flow of an appointment like an interruption. A call from the lab, a question from the front desk, a personal call you choose to answer. Each one breaks your concentration and robs you of minutes you never get back.

My rule was simple: never interrupt me when I’m with a patient. That meant I never accepted a phone call when someone was in the chair. I used to say to my staff:

“If the practice is on fire, come and tell me. If it’s not, I don’t want interruptions.”

The bonus for being interruption-free is that patients love having your undivided attention. They feel better cared for when you’re fully present with them.

12. Allowing anxious or talkative patients to control the pace

Some patients slow the appointment without meaning to.

They ask many questions, tell long, irrelevant stories, or need extra reassurance. I once had a patient who removed his shoes so he could show me a problem with his feet. Inefficient dentists let the patient set the tempo. Efficient dentists guide the appointment.

Friendly, yes — but direct. You set the pace. You set the structure. You lead the appointment. If a patient was disrupting my day with too much talking I would say to them: “We need to get on with things right now or we won’t be able to finish.”

If they kept disrupting I would cut down the amount of treatment and let them know why.

13. Starting the day already behind

Arriving late is a self‑inflicted injury.

It’s unnecessary, avoidable, and it sets off a chain reaction that affects every patient and every procedure. When you walk in late (or even just on time) you begin the day in a defensive state. You lack preparation and you have no margin for error.

Efficient dentists arrive early, 15 minutes before the first patient is a good guide. They review the schedule (preferably in a morning huddle, which is covered in the next point), anticipate challenges, and set the tone for the team. I found that time let me settle and focus.

A day that begins smoothly usually stays smooth. A day that begins in a rush rarely recovers.

14. Not reviewing the day’s schedule or anticipating complications

Many dentists walk into the day without reviewing the schedule, and it costs them dearly. They discover problems only when they’re already in the room — a missing lab case, a patient who always needs extra time, or a procedure that was booked too tightly.

Even worse, they fail to anticipate the complications that they could have seen coming. A deep restoration that may turn into endodontics, a cracked tooth that may require a crown rather than a filling, or a patient with a strong gag reflex who will need more time.

When you don’t anticipate these issues, you lose time reacting to them.

Efficient dentists review the schedule and mentally rehearse the day before it begins. A morning huddle with the team is where they look ahead, identify the likely challenges, and prepare for them. When the complication arrives, it isn’t a surprise. It’s already accounted for.

15. Allowing incomplete treatment plans to slow everything down

A surprising amount of lateness comes from unclear treatment plans.

When the dentist hasn’t got a clear, written treatment plan the appointment becomes a guessing game. I’ve been in practices where the treatment plan is written in the patient chart as “NV CT” (“Next Visit Continue Treatment”). That is completely vague and hopeless.

In such practices, the nurse sets up for one procedure while the dentist is thinking of another, and the patient believes they’re having something different again. Time is lost clarifying, explaining, resetting expectations, and reorganising.

Dentistry moves fastest when everyone in the room knows exactly what is happening. A clear written treatment plan that’s communicated to both the patient and the team, eliminates confusion and gets the appointment moving from the moment you sit down.

16. Not managing late‑arriving patients

Some dentists allow late patients to derail their day.

A patient arrives fifteen minutes late, and instead of adjusting the plan, the dentist tries to deliver the full appointment in less time. This creates stress, and a schedule that rarely recovers.

Of course you need to be sensitive to genuine emergencies in a patient’s schedule but, other than that, efficient dentists must protect the integrity of their day. If a patient arrives late, the appointment should be shortened or rescheduled. It’s not punitive — it’s practical.

I used it as a teaching moment for late patients and after missing out on expected treatment very few patients came late a second time. It goes without saying that this presupposes that you run on time. You can’t train patients to respect your time if you don’t respect theirs.

By shortening a late-arriving patient’s visit, it preserves the flow of the day, respects the patients who did arrive on time, and keeps you in control rather than scrambling to catch up. A schedule only works when it’s treated as something worth defending.

17. Allowing emergencies to disrupt your schedule

One of the fastest ways to lose control of your day is to let emergencies walk straight into the middle of it.

You have the perfect schedule planned, everything is balanced, and then someone walks in off the street saying they have a toothache. You want to help them — of course you do — but jamming them into an already full day pushes everything over the edge. Suddenly you’re stressed, the team is scrambling, and you’re thirty minutes behind with no way to recover.

The truth is simple: emergencies must wait. They cannot be allowed to disrupt the patients who booked ahead, arrived on time, and trusted you to run your day professionally.

Efficient dentists have a clear policy. Emergency patients are seen at the next available gap, or at the end of the session, or in a dedicated emergency slot but never at the expense of scheduled patients. When you guard the structure of the day, you respect everyone in it.

Final thoughts

When you’re behind schedule, your communication gets worse, your decision making deteriorates, your team becomes anxious, and your patients feel the pressure. It becomes a loop.

But when you’re on time, everything works better. Your team moves with ease and your patients appreciate the smooth rhythm. Dentistry is easier and more fun. Being on time isn’t an optional luxury. It’s part of clinical competence and affects your enjoyment of practice.

Running late can sometimes be a personal failing but more often, it’s a system failing. Fix the system, and you fix the problem.

If you have a regular problem with running late, you should find the causes somewhere in this list. No dentist I’ve ever met has all seventeen issues, but those who chronically run late usually have three, four, or five of them working against them at the same time. The first step to fixing the problem is honest reflection.

Efficiency isn’t a personality trait you either have or don’t. It’s a form of respect — for your patients, your team, and the craft itself. And like any act of respect, it’s a choice you can make starting tomorrow.
