hi Hi Human
On running a practice

Every call that rings out is a patient deciding whether to wait, or to dial the practice down the road. Here is what that really costs, and how to stop the leak.

Hi Human · 6 minute read

Most practices have no idea how many calls they miss. The phone rings during a scale and polish, at lunch, after five, or while the front desk is checking in three patients at once. Nobody logs it, nobody hears it, and the caller simply moves on. The cost of missed calls for a dentist is the quietest line on the P&L, because it never appears on the P&L at all.

A busy practice can field dozens of calls a day, and the ones that go unanswered cluster at exactly the moments the team is most stretched. We will not invent a national “calls missed per day” figure, but you can measure your own in an afternoon, and most practice managers who do are quietly horrified by the number.

What one missed call is actually worth

Not every missed call is a lost patient. Plenty are existing patients who will ring back, or suppliers, or wrong numbers. The expensive ones are the new-patient enquiries, because someone ringing round is comparing you against two or three other practices in the same ten minutes. Whoever picks up first books them. Voicemail books nobody.

Put a number on it. A new private patient is worth somewhere around £2,000 to £5,000 in lifetime value once you count treatment, hygiene visits and referrals. That is illustrative, not a promise, and the real figure depends on your mix. But it reframes the maths: a single missed new-patient call is not a missed £60 check-up, it is a missed relationship that would have paid out for years.

The same leak shows up on the other side of the diary. Roughly one in six NHS dental patients fails to attend at least one appointment a year, around 17% on the published figures, and a good chunk of those no-shows are people who could not reach you to rebook or cancel, so they did nothing. A chair sitting empty at half past two is the cost of a missed call you never knew happened.

Why the front desk cannot win this on its own

None of this is the receptionist’s fault. A human at the desk holds one conversation at a time, so when two lines ring during a checkout, one of them loses, every time. Lunch breaks, holidays, sickness and the end of the working day all leave hours where nobody is there to pick up at all.

And good reception staff are not cheap, nor should they be. A full-time dental receptionist costs a practice about £26,000 a year once you add employer National Insurance at 15% and a 3% pension contribution on top of salary, on the 2025/26 government rates. A part-time hire still runs around £14,400 a year. That money buys skilled, warm, in-person care for the patients at the desk. It does not buy a second pair of ears for the calls arriving while that care is happening.

Some practices plug the after-hours gap with a telephone answering service, typically £2,400 to £4,740 a year for a few hundred minutes of message-taking. That stops the phone ringing into the void, but a message in the morning is not a booking made the moment the patient was ready to commit. The enquiry that rang at 7pm has, by 9am, often already booked somewhere that answered.

The leak is bigger than your software bill

Here is the part that stings. A typical practice already pays roughly £2,220 to £6,180 a year for its cloud practice-management system alone, before a single call is answered. You are paying handsomely to run the diary, yet the missed calls are the patients who never make it into that diary in the first place. The most expensive software in the building does nothing for the enquiry that rang out at lunchtime.

You can buy a better diary, but the diary does not answer the phone. The leak is upstream of all of it.

How to find your own number this week

Before changing anything, measure. You cannot manage a cost you have not seen.

• Pull your call logs. Most phone systems report missed and abandoned calls. Look at a normal week, not a quiet one.
• Mark the patterns. The first hour, the last hour and the lunchtime rush are the usual suspects.
• Estimate the new-patient share. Guess how many misses were first-time enquiries, multiply by that £2,000 to £5,000 range, and you have an annual figure that focuses the mind.
• Add the no-shows you could not prevent. Count the failed appointments where the patient could not get through to change them.

Do that honestly and the cost of missed calls usually dwarfs every other line you have been agonising over. It is the rare practice problem where the fix pays for itself before the quarter is out.

The fix: answer every call, without burning out the desk

The goal is not to replace your receptionist. It is to make sure no call ever goes unanswered, so your team can give their full attention to the patient in the chair instead of lunging for a ringing phone. That is the job an AI receptionist is built for: it picks up on the first ring, every ring, at 2am or during the lunchtime rush, and it holds many conversations at once without ever leaving a caller on hold to die in a queue.

Our AI receptionist, Hannah, answers in a natural voice, books and reschedules straight into your diary, handles the routine questions that eat the front desk’s day, and passes anything clinical or sensitive to a human. The receptionist you already pay for stops being a switchboard and goes back to being the warm face of the practice. You can see how that works for dental and healthcare practices, and the cost of never missing a call is published openly on our pricing page, not hidden behind a quote.

An honest note on cost

We are not the cheapest option, and we will not pretend to be. US-built AI receptionist tools commonly start at $300 to $800 a month; UK dental AI receptionists tend to run roughly £83 to £295 a month depending on volume and features.

The point is not the lowest price. It is the return. If answering one extra new-patient call a month is worth £2,000 to £5,000 over that patient’s lifetime, the question is no longer whether you can afford it. It is whether you can afford the calls you are already losing.

For practices that want it on their own terms

For most practices, well-run UK-hosted software answering the phone is exactly the right call, and that is what we run for clinics today, including ndu Clinic on Harley Street. For those who want the intelligence to live physically inside the building, we are building Hannah Sovereign, a bespoke on-site version where patient data is processed on the premises. It is early, so we are opening a waitlist rather than shipping it off the shelf. That is a question of control and procurement preference, not a claim that data is forbidden from crossing a border. Lawful transfers happen every day, and we will not oversell it.

The phone is still the front door of a dental practice. Every call that rings out is someone who chose to call you and met silence. Measure the leak, then close it, and let your team delight the patients in front of them rather than chase the ones who already hung up.
