Dental Consent Versus Radiographic Reality: A Resorptive Canine and a $600 Cap
A 9-year-old, 6.4 kg neutered male Yorkshire terrier is presented for a "dental." The signed consent form reads "dental cleaning, with extractions if needed, up to $600." Pre-anesthetic blood work is unremarkable apart from ALP 210 U/L; creatinine is 1.1 mg/dL. Under anesthesia, you chart grade 3 calculus and gingivitis, a 4 mm probing depth at the right maxillary fourth premolar, and a fractured right maxillary canine with a dark area at the gingival margin. Full-mouth intraoral radiographs show approximately 40% remaining bone support with furcation involvement at the right maxillary fourth premolar, and a wide cervical radiolucency on the right maxillary canine that extends into the pulp cavity, consistent with a resorptive lesion. The veterinarian begins a surgical extraction of the fourth premolar and asks you to prepare for the next tooth, then pauses and says, "We need to talk to the owner about that canine." The owner is at work and has given a mobile number. The estimate for a surgical canine extraction, including a mucogingival flap and possible bone removal, is $780 on its own.
1. Which findings change the plan, and why does the original signed consent not cover the next step?

Findings that alter the plan
- Right maxillary fourth premolar: ~40% bone support with furcation involvement. This is not a simple extraction; it requires a surgical approach (flap, possibly sectioning and alveoloplasty) and takes time.
- Right maxillary canine: a cervical radiolucency extending into the pulp cavity. This is tooth resorption, and the treatment decision belongs to the veterinarian: extraction versus crown amputation with gingival closure depends on how much root is replaced by bone-like tissue and whether the tooth is restorable. Either option is a significant procedure with a real aftercare burden (soft food, no chewing on that side, analgesia, possible flap dehiscence).
- The dark spot the owner can see is not a reliable diagnosis; the radiograph is what distinguishes resorption from pulpal exposure, and the technician's job is to make sure that image exists and is documented.
Why the consent falls short
- "Extractions if needed" authorizes the category of procedure, not an unbounded cost. The owner set a $600 ceiling; the canine extraction alone is estimated at $780, before the fourth premolar.
- A reasonable client reading of that form is "clean the teeth and pull the bad ones," not "perform two surgical extractions totalling well over a thousand dollars." Proceeding would create a billing dispute and, more importantly, an uninformed consent.
- Anesthetic time also matters: two surgical extractions in a 6.4 kg geriatric patient lengthen the procedure and change the risk conversation.
- The correct move is to pause, have the veterinarian state the findings and options in plain language, obtain a specific authorization (or a specific decline), and record it. If the owner cannot be reached, the veterinarian decides what is in the patient's immediate interest and what can reasonably wait.
2. What must go into the medical record for this appointment, beyond the usual anesthesia log?
Read the worked answer
Dental charting
- A full-mouth chart: probing depths at six sites per tooth, gingival index, calculus and plaque scores, furcation grade, mobility, and any fractures or resorptive lesions, tooth by tooth.
- The pre- and post-extraction appearance of each site, including the flap design and closure method used.
- A note that radiographs were taken and where they are stored.
Imaging
- Full-mouth intraoral series, labelled with patient name, ID, date, and the tooth and view for each image. The canine and fourth premolar views are the ones a future clinician will want; they should be retrievable, not lost in a folder.
Consent and communication
- The original signed estimate and consent form, scanned.
- The time of the call, who answered, what the veterinarian disclosed (findings, options, risks, estimate), the client's exact decision and words, and the name of the veterinarian who obtained it.
- If the client declined a recommended extraction, record that it was offered, understood, and declined - this protects the patient and the practice.
Drug and procedure record
- All drugs with dose, route, time, and who administered them; local blocks and the agent used; total anesthetic duration.
- Discharge instructions issued, including analgesia, feeding, and what to watch for.
The principle: if it is not written down, it did not happen, and a chart that cannot be reconstructed six months later is a liability rather than a record.
3. Write the substance of the telephone call to the owner. What do you say, and what do you deliberately not say?

Structure the call
- Identify yourself and the patient, and confirm the owner has a moment and is somewhere private. Never deliver unexpected cost news to someone in a meeting.
- Give the headline first: "The cleaning is done and Scout is stable. The X-rays showed two teeth that need more than a routine extraction, and Dr. - needs your decision before we continue."
- Translate the findings, using the words the veterinarian has authorized: "One is a big upper tooth at the back with about 40% of the bone gone - that one is already out. The other is the upper canine, which has a cavity-like lesion that has reached the nerve. It can't be saved."
- State the options and the numbers plainly: extraction versus crown amputation if the veterinarian considers it appropriate, the estimate, the added anesthetic time, and the aftercare.
- Ask for a specific decision and read it back: "So that's approval for the canine extraction at $780, on top of the $600 already approved - is that correct?"
- Give a realistic time frame for the call-back and the pickup, and tell the owner who will call with the discharge instructions.
Deliberately not
- Do not diagnose beyond what the veterinarian has stated, and do not predict the outcome of a procedure you are not performing.
- Do not pressure with "he'll be in pain if you say no" - present the consequence factually and let the owner choose.
- Do not quote a firm final price for a surgical extraction that may require bone removal; give the estimate as a range and say what would change it.
- Do not agree to "just do whatever is cheapest" - ask which option the owner is authorizing.
