Does a dentist have to see emergency patients who are not patients of record?

The ADA Code of Professional Conduct, section 4.B, obliges a dentist who is consulted in an emergency by a patient not of record to make reasonable arrangements for emergency care. Arrangements, not treatment. A referral to a named colleague, a hospital dental service or an emergency clinic can be a reasonable arrangement. What the Code does not contemplate is a caller with no arrangement at all. State law and the practice's own attorney govern the specifics; the post reads the Code and the ADA's practice guidance and is not legal advice.

What should a dental office voicemail say to callers who are not patients?

Three things, according to the ADA's emergency-treatment guidance read alongside the Code: whether the practice sees emergencies from people who are not its patients, a real destination for the ones it does not see (a name and number or a place, not an instruction to find one), and how to reach the practice when it opens. The ADA's guidance says the office "should be prepared to provide referral information to individuals who are not patients of record," and the voicemail is the first place that information is needed.

What does the Code mean by returning the patient to their regular dentist?

The third sentence of 4.B says that if treatment is provided, the dentist, on completing it, is obliged to return the patient to their regular dentist unless the patient expressly says otherwise. It tells you what the arrangement is for: coverage, not acquisition. In practice it means the emergency visit ends with the front desk asking who the patient normally sees and whether to send that office the record of the visit.

What is a mutual aid agreement in dentistry?

An arrangement between practices to cover each other's emergency calls, including from callers who are not patients of either. The ADA publishes Guidelines for the Development of Mutual Aid Agreements in Dentistry, which its emergency-treatment page points to as a resource for the practice's contingency plan. The guideline is an ADA store item rather than a free page, which is why the post describes it rather than quotes it.

What does Laine do with an after-hours call from someone who is not a patient?

Laine answers the call and says what the practice wrote for that caller, in the caller's language, over 90 of them. If the practice refers out, the caller hears the name and number the dentist chose. If the practice sees emergencies from callers not of record, Laine can book them into the schedule in Dentrix, Dentrix Ascend, Open Dental or CareStack with the reason for the call attached. Laine does not decide whether the practice sees them, does not choose the referral and does not call anyone back. Those are the dentist's decisions, made in writing before the phone rings.

The Third Message

September 23, 2026 · 6 min read

In 2006 the ADA's ethics column in its own journal took up a question that still sits in the archive, filed under emergency service: what are my ethical obligations in handling after-hours calls from patients of other dentists in my community?

Read it from the other side. Somewhere in your town there is a dentist whose phone rings at night with your patients on it, because your voicemail told them to call someone else and did not say who. And somewhere in your own voicemail box there are people who have never been to your office, listening to a recording that was written for people who have.

The previous post on this blog took the ADA's after-hours guidance and found it asks the closed-office voicemail to do three things: send a life-threatening emergency to 911, give patients of record a number that reaches the dentist, and include emergency information for people who are not patients of record. It gave the third one two sentences. This is the rest of them.

What the third message is for

The ADA Code of Professional Conduct, section 4.B, is three sentences long. The first obliges the dentist to make reasonable arrangements for the emergency care of patients of record. The second extends that to patients not of record who consult the dentist in an emergency. The third is the one nobody quotes: "If treatment is provided, the dentist, upon completion of treatment, is obliged to return the patient to his or her regular dentist unless the patient expressly reveals a different preference."

That sentence tells you what the arrangement is for. It is not a new-patient funnel. The Code assumes the person calling you at night has a regular dentist, assumes you might see them, and assumes you send them home afterward. Coverage, not acquisition. Which means the third message on your voicemail is not a marketing decision and does not need to sound like one. It is the practice saying, to someone who is not its patient, where they can get help tonight.

The ADA's emergency-treatment guidance says the practice should be ready for exactly that: "Your office should be prepared to provide referral information to individuals who are not patients of record but who do contact you for emergencies." Referral information. The guidance does not say see them. It says be ready to tell them where to go.

Why referring out is a complete answer

Most dentists hear "callers who are not patients of record" and feel the pull in two directions at once. Turning them away feels wrong. Seeing them feels like an obligation the practice cannot carry every night.

The Code resolves this with less drama than either instinct. Reasonable arrangements. Not treatment, arrangements. If the arrangement is a named colleague who covers callers not of record, a hospital dental service, an emergency clinic that takes walk-ins, or your own morning schedule with the first available slot, that is reasonable. The ADA even wrote a guideline for the formal version, its Guidelines for the Development of Mutual Aid Agreements in Dentistry, which the emergency-treatment page points to and which sits in the ADA store. Mutual aid is the profession's own name for two practices agreeing to hear each other's third message.

What is not reasonable is the voicemail that says "if this is a dental emergency, please contact another dentist" with no name and no number. That sends the caller back to the search results at night, in pain, and it sends the 2006 question to whichever dentist in your town answers their own phone. That dentist did not agree to be your arrangement.

What the message actually has to say

The circulating scripts, and there is no shortage of them, get the first two lines right and then fold everyone else into "for all other calls, please leave a message and we will return your call the next business day." The person who is not your patient and has a broken tooth at night is in "all other calls." That is the whole problem in one sentence.

The third message needs three things, and none of them is long. It needs to say plainly whether the practice sees emergencies from people who are not its patients, because a caller cannot plan around a maybe. It needs a real destination for the ones it does not see: a name and a number, or a place, not an instruction to go find one. And it needs to say how to reach the practice when it opens, for the caller who can wait and would rather become a patient of record than call around.

Written down, it fits in the time it takes to say it. What takes longer is the decision behind it, which is the dentist's, and has to be made once, in daylight, not by whoever recorded the greeting.

If you do see them

The third sentence of 4.B has one more thing to say to the practice that takes the call and treats the patient. Upon completion of treatment, return the patient to their regular dentist unless they say otherwise. In practice that means the emergency visit ends with a question the front desk should be ready to ask: who do you normally see, and would you like us to send them the record of tonight. It is a courtesy the Code has made an obligation, and it is also how the dentist across town finds out that his third message worked.

Where Laine fits, and where it does not

When someone who is not a patient of record calls after hours and the practice's phone is answered by Laine, Laine says what the practice wrote. If the practice refers out, the caller hears the name and number the dentist chose, in the caller's language, over 90 of them, and is not left with a recording that was not meant for them. If the practice does see emergencies from callers not of record, Laine can put them on the schedule, into Dentrix, Dentrix Ascend, Open Dental or CareStack, with the reason for the call attached, so the morning huddle is looking at a booked patient rather than a voicemail.

What Laine does not do is decide any of this. Whether the practice sees callers not of record, who the referral is, what the dentist's own emergency number is: those are the dentist's decisions, written before the phone rings. Laine does not call anyone back, and it does not make the judgment the Code leaves with the dentist. It makes sure the third message is said to the person it was written for, every time, instead of once in a recording.

We do not lock anyone into a long-term contract and there is no onboarding fee. Writing the third message is the first piece of work, and it is yours.

Call your own main line after closing and listen to the whole recording as someone who has never been to your office. If it does not tell that person where to go, that is the message to write.

The Caller Who Tried Twice

"We must have been on the other line" is a guess, and patients can hear it. Once the scheduling coordinator has looked at the call log, she can say what actually happened, ask what the call was about, and find everyone else who tried twice and never made it to the counter.

The Teenager Who Drove Himself

A seventeen-year-old with a license walks up to the counter by himself. May he be seen today, and who gets told what afterward? The first answer belongs to your state. The second is a federal rule most front desks guess wrong. Both belong on one page the doctor writes before he arrives.

Reading Your Own Call Log

"I called earlier and nobody picked up." The front desk apologizes and guesses. The phone system knows: it wrote a row for that call the moment it came in. This post walks through a call log column by column, shows why the word "missed" means something different in each phone system, and says what a row will never tell you.
