The Cat Whose Owner Wants 'Just a Cleaning'
A 9-year-old castrated male domestic shorthair cat weighing 5.2 kg is presented because the owner has noticed drooling and "chewing on one side" for 3 weeks. The cat has lost 0.6 kg since last year's visit. He is bright and interactive but resists opening his mouth. Awake oral examination shows heavy calculus, gingival recession with exposed furcation on the maxillary right fourth premolar (tooth 108), which is mobile; a mobile mandibular right canine (tooth 404) with a dark line at the gingival margin; and a pink, proliferative lesion at the gingival margin of the mandibular left first molar (tooth 309). The owner says, "I just want them cleaned - no extractions, and please don't put him under; my last cat was groggy for two days. Can't you just give antibiotics?" The estimate for a full-mouth dental with radiographs and possible extractions is $850–$1,200, and the owner has a $500 care-credit limit.
1. How would you explain why an anesthesia-free dental cleaning is not an acceptable substitute here, and how would you address the owner's fear about anesthesia?

Anesthesia-free cleaning: it removes only visible calculus above the gumline. It cannot probe periodontal pockets, debride subgingivally, take radiographs, or treat the lesions this cat actually has. It is cosmetic, it can hide progressing disease behind a clean-looking crown, and it requires restraint that is stressful and carries injury risk in a cat with mobile teeth. It would not address the pain, the mobility, the resorptive-looking lesion, or the mass.
The anesthesia concern is legitimate - take it seriously rather than dismissing it. Two days of grogginess is usually attributable to long-acting sedatives, hypothermia, uncontrolled pain, or a rough recovery, not to anesthesia being inherently dangerous. Explain the mitigations: a pre-anesthetic examination and bloodwork, individualized drug protocol, airway protection with an endotracheal tube (which also prevents aspiration and water in the airway during scaling), local nerve blocks so less general anesthetic is needed, active warming, IV fluids, and dedicated monitoring by a technician. Anesthesia in a stable 9-year-old cat with normal labs carries a low risk; untreated periodontal disease and oral pain carry a much more certain one.
Frame the choice honestly: she can decline treatment, and you will document that. But "just a cleaning" is not a treatment option that matches these findings, and saying so is your job.
2. Prioritize the findings and build a treatment plan, including what you expect radiographs to show and the analgesia you would plan.

Priority order: the mass at 309 and the painful, mobile teeth first; the generalized calculus last.
- Tooth 108 - furcation exposure plus mobility means stage 3 periodontitis with attachment loss; extraction is the realistic option, not scaling.
- Tooth 404 - mobility and a dark line at the gingival margin raise suspicion of a resorptive lesion (feline odontoclastic resorptive lesion); radiographs will show whether the root is resorbing or ankylosed, and extraction technique depends on that.
- Tooth 309 mass - a pink proliferative lesion at the gingival margin in an older cat must be biopsied or excised and submitted for histopathology to rule out squamous cell carcinoma or other neoplasia. Waiting to "see if it changes" is the wrong call.
What radiographs add: full-mouth intraoral films reveal root resorption, retained roots, bone loss, periapical lucency, and lesions that are invisible on exam - they change the plan in a large fraction of feline dentals. They are taken before extractions, not after.
Analgesia: premedication with an opioid (e.g., buprenorphine), NSAID if renal parameters are acceptable, and local blocks - inferior alveolar nerve block for 404 and the mandibular quadrant, maxillary nerve block for 108 - which reduce intraoperative anesthetic requirement and provide postoperative comfort. Antibiotics are not a substitute for source control in a healthy cat with periodontitis; they are for systemic infection, immunocompromise, or as an adjunct when indicated, and they will not treat a mobile tooth or a mass.
3. The owner has $500 and wants everything done "in one go." Draft the consent and communication plan, including what you would do today and what you would defer, and what you document.

Staged plan with a written estimate. The estimate must be a range, in writing, with the high and low numbers, and an authorization line such as "up to $X without further approval." Also confirm who may be called if the cost changes mid-procedure.
Today (fits the budget): examination under anesthesia, full-mouth radiographs, charting, supragingival and subgingival scaling and polishing, extraction of the clearly painful mobile teeth (108 and 404), local blocks, and biopsy or excision of the mass at 309. Treating pain and getting a diagnosis cannot be deferred without real risk.
Deferred: polishing of areas not yet instrumented, further extractions of stable teeth with milder disease, and the recheck radiographs - scheduled now, with the owner told what happens if she defers indefinitely.
Conversation structure: name the findings plainly, show her the radiographs on the screen, explain the two-tier priority (pain and cancer risk first, cosmetics and prevention second), and use teach-back. Make clear that antibiotics alone will not fix this and that not treating the mass carries a risk of missing a malignancy.
Documentation: the oral exam findings by tooth number, the estimate presented and accepted, the owner's financial and treatment decisions, which teeth were extracted, the biopsy submission, analgesia and anesthesia drugs and doses, and the recheck appointment. If she declines any part, record that it was offered and declined, without editorializing.
