When Your Dentist and Your Doctor Have to Work on the Same Person

Picture the patient. Her doctor, or her surgeon, has told her the treatment is set for the twentieth. Somewhere in that conversation, almost as an aside, the doctor says: get your teeth looked at first.

That is the whole handoff. A sentence.

Here’s what care coordination between a dentist and a doctor actually means: one person, or one team, holds the whole picture while the patient moves between two offices that don’t share a chart. They know why the doctor wants the teeth looked at, what the dentist found, what the hospital needs back and by when, and they get it there without the patient carrying it by hand. When that exists, the treatment date holds. When it doesn’t, the patient becomes the courier.

Now she has to find a dentist who can see her this week, explain why she is there, explain what the doctor is worried about, remember what the hospital wants in writing, and get it there before the twentieth. She is the only person who has been in all three rooms. She is sick, and she is the courier.

I read the paper this walk leaves behind: the referral that was sent, the note that came back, the claim that followed. You can see the whole failure in it. A front desk that got a call about a patient with a condition they’d never heard of and a deadline they didn’t set. A hospital coordinator waiting on a letter nobody specified. A patient who’s been to both offices and is still the only one holding the full story.

Why don’t the dentist and the doctor share a chart?

The mouth has its own office, its own insurance, its own paperwork, and its own software. For most of life that separation is just an inconvenience. The moment a doctor and a dentist have to work on the same person at the same time, it becomes the problem.

Here’s how far apart the two worlds still are. Epic, one of the largest medical records companies in the country, reported in January 2026 that dentists using its system avoided more than 260,000 potential drug interactions in a year, because for once the dentist could see the full medical record. That’s what happens when the two charts are one chart. Epic also reports about 2,300 dental clinics on its system. Set that against every dental office in the country and it’s a sliver. For almost everyone, the two charts are still two charts, and the patient is the bridge between them.

One more number from the same Epic report, which cites a federal survey (AHRQ, Medical Expenditure Panel Survey, Statistical Brief 537): about nine percent of Americans, more than 28 million people, saw a dentist in the past year and did not see a medical doctor. I’m quoting Epic’s reading of that brief, not my own. For 28 million people the dental chair is the only exam room they sit in. If the dentist and the doctor are not connected, that visit is a dead end for anything the dentist notices.

What does coordination look like when it works?

It isn’t complicated. It’s just owned.

Someone takes the doctor’s sentence and turns it into a request with a date on it. Someone calls the dental office with the context, not just the appointment: who is asking, why, what they need back, and by when. The dentist sees the patient already knowing the situation. The write-up goes back to the office that asked for it, in the form that office can use, before the date. The patient tells her story once, at the start, and after that the story travels without her.

When it works, the treatment date holds. The patient spends her energy on the treatment, not the logistics. Both offices feel like the other one finally did its job, when what actually happened is that a third person did the job between them.

What does it look like when it fails?

The sentence stays a sentence. The patient calls dental offices from a list and takes the first one that can fit her in. That office has no idea why she is there beyond “my doctor said”. The dentist does what dentists do and writes what dentists write, which is not what the hospital needs. The letter, if there is one, goes to the patient, who drives it over. The hospital reads it, finds it does not answer the question, and asks for another visit. The twentieth comes and goes.

Nobody in that chain did anything wrong. Each office did its own job. The failure lived in the space between the offices, and nobody works there.

I use one rule for every referral, in any direction: a referral isn’t complete when it’s faxed. It’s complete when the patient reaches the next provider with their story intact, and the result comes back to the person who asked. By that rule, most referrals I’ve read were never completed. They were sent.

What’s the one question a practice can ask itself this week?

Of the patients a physician sent you to look at before a hospital treatment last month, how many were seen, written up, and had the letter back to the requesting office before the hospital’s date?

If the answer is a number, you are coordinating. If the answer is “I would have to check with the front desk”, the coordination is happening by luck, and the patient is the one carrying the risk.

Hospital coordinators can ask the mirror question. Of the patients you told to get their teeth looked at before treatment, how many came back cleared on time without you or the patient chasing it?

Why do I care about the space between the offices?

Health starts from the mouth, and the mouth is treated last. I’ve said that for years, and the place where it costs people the most isn’t a philosophical debate. It’s this handoff. The moment the body most needs the dentist and the doctor to act as one team is the moment the system splits them furthest apart and hands the patient the job of holding them together.

I’m not asking anyone to rebuild medicine. I’m asking that someone own the walk. A planner, a navigator, a coordinator, a practice that decides the referral is not done until the patient is seen. The walk is short. It only feels long because nobody is walking it with the patient.
