Who says a dentist isn’t a doctor?

Sometimes I wish medical school had a dental component to their curriculum. You will understand why I say this with our next tooth story. It just might blow your mind! When it comes to medical issues that don’t obviously involve teeth, diagnosis can be tricky for other physicians. They sometimes don’t realize they should refer their patients to a dental professional, and this ends up hurting their patients.

When I went to the Dentsply Sirona Key Opinion Leader meeting earlier this year, I was super impressed when my friend and colleague, Dr. Michael Thompson, shared this mega tooth story. Because it made such an impact of me, now I want to share it with you!

 

This case is about a 17-year-old female patient.

Besides an allergy to penicillin, she was medically healthy. In 2014, she presented to her primary care provider (PCP) with pain to her left ear. The PCP diagnosed the patient with an earache (acute otitis externa) and treated her with several rounds of topical and oral antibiotics and analgesics.

Unfortunately, she had no resolution of her symptoms and subsequently she developed submandibular swelling. She returned to her PCP with continued symptoms, and her provider referred her to a plastic surgeon.

The plastic surgeon suspected a cyst in the submandibular region and removed what they thought was the cyst.  Unfortunately, the surgical site did not heal, and the patient had several more rounds of antibiotics.

The saga continued from referral to referral.

In 2015, the patient saw an ENT, who gave her a prescription for yet more antibiotics. The ENT also ordered a CT. The radiology report indicated a “periapical cyst involving the left mandibular molar compatible with odontogenic disease, draining to the skin in the left submandibular region,” and they recommended a dental evaluation.

The ENT referred the patient to OMFS, and then OMFS finally referred the patient for an endodontic consult. By this point it was 2016, and the poor young woman’s chief complaint was that “pus had been oozing out of her neck for about a year.”

Upon clinical evaluation, there was a visible draining cutaneous sinus tract in the submandibular region.

Here are the radiographs from the patient’s general dentist.

The CBCT evaluation looked like this.

And this is the 3D rendering, showing the resorption of the mandible.

All her probings were in normal limits, there was no mobility, and she had no pain to percussion or palpation. Tooth #18 did not respond to cold. Therefore, her dentist diagnosed tooth #18 with a Necrotic Pulp and Chronic Apical Periodontitis.

Finally, she would have a root canal.

The patient’s dentist knew Dr. Thompson was just the dental professional to do it! Because this case needed extra attention, he completed this root canal treatment in multiple visits.

He used calcium hydroxide as the intracanal medicament. Two weeks later, he invited her back for a follow-up and another round of calcium hydroxide. You can see that the soft tissue was starting to respond well.

And here is a CBCT view of the postoperative root canal.

At 7 months, Dr. Thompson recalled the patient again and was pleased to see everything was responding perfectly. The soft tissue was most definitely healing, and the bone was also starting to regenerate around the apex.

At her 18 month recall, she was still improving, and the tooth had been restored. Surely, she was relieved to have saved her tooth and for the lesion under her chin to be resolving!

 

The takeaway from this story

This tooth story hurts my heart, and I honestly relate to it, given my own referral nightmare. Unfortunately, when it comes to physicians in other medical specialties, they don’t always consider the impact of teeth; diagnosis becomes a wild goose chase in these instances. This only hurts the patient at the end of the day.

It’s hard just thinking about what this young lady went through physically, socially, and financially for over 2 years. I’m glad she eventually got a referral to Dr. Thompson, who has been able to give her the relief she’s needed for so long.

Yes, I know it’s impossible to completely eliminate stories like these, but I want to encourage and challenge my colleagues to create more overlap between the medical and dental world. As we better understand each others’ specialties and keep the door open to communication and referrals, we can all do our part to keep these stories to a minimum.
