Fractured Carnassial and a $900 Budget
A 10-year-old female spayed Yorkshire terrier weighing 4.3 kg is presented for halitosis, dropping food, and pawing at the face. Awake examination shows grade 3 periodontal disease, 2–3 mm of attachment loss on both maxillary canines, mobile mandibular incisors, and a fractured right maxillary fourth premolar (tooth 108) with a visible pink pulp exposure. Preoperative bloodwork is unremarkable and the dog is otherwise healthy. Under anesthesia, full-mouth intraoral radiographs and probing show: tooth 108 with a wide canal and a 3 mm periapical lucency; tooth 308 with more than 50% horizontal bone loss and root resorption; teeth 104 and 204 with 1 mm pockets and no mobility. The owner's budget is $900. A referral practice quotes $1,800–2,400 for root canal therapy on 108. The owner says: "Can't you just scale the tartar off and give him a pill? I don't want him to lose teeth."
1. Interpret the radiographic findings and decide what to do with teeth 108, 308, and 104/204.

Tooth 108 has a fractured crown with pulp exposure, a widened canal, and a 3 mm periapical lucency: the pulp is dead and infected, and there is apical periodontitis. Two acceptable options exist - extraction, or root canal therapy by someone trained to do it - and "watch it" is not one of them. Extraction of 108 means a surgical extraction with a mucoperiosteal flap and sectioning of the mesial and distal roots; it is not an elevator-and-pull job.
Tooth 308 has more than 50% horizontal bone loss plus root resorption and mobility. That tooth is not restorable and extraction is the correct call, with attention to the mandibular canal and the thin lingual cortex in a 4.3 kg dog.
Teeth 104 and 204 with 1 mm pockets do not need extraction - they need subgingival scaling, polishing, and home care. That distinction is exactly what charting and radiographs are for. Present both options for 108 with the $1,800–2,400 referral figure against her $900 budget, let her choose, and document the conversation and reasoning either way.
2. The owner asks for scaling only, without anesthesia, plus "a pill" instead of extractions. How do you respond?

Say no, and explain rather than simply refusing.
Scaling without anesthesia removes only supragingival calculus. The subgingival biofilm that drives attachment loss, and the bone loss visible on these radiographs, cannot be reached by a hand scaler on an awake, painful dog. There is no probing, no radiograph, no extraction of 308 or 108 - so the painful teeth stay painful and the disease progresses. There is also a real safety problem: scaling an awake dog risks aspiration and injury, and a painful dog is a dog that bites.
Antibiotics are not a substitute. Periodontal disease is treated by mechanical debridement; antibiotics given without it select for resistance while biofilm re-forms within days.
Offer what is possible within her budget - a staged plan, extraction of the two hopeless teeth, conservative care elsewhere - rather than an all-or-nothing proposal. If she declines anesthesia entirely, document the recommendation, the risks explained, and her refusal, and schedule a recheck focused on pain and quality of life.
3. Design the postoperative analgesia and home-care plan for this 4.3 kg dog.

Post-extraction pain in a small dog should be planned before the dog wakes, not after.
Multimodal: an NSAID such as meloxicam 0.1 mg/kg on day 1 then 0.05 mg/kg q24h if renal and hepatic values are normal with no GI contraindication, an opioid for the first 24–72 hours (buprenorphine or tramadol per the veterinarian), and local anesthetic blocks at the time of extraction.
Owner instructions: soft food for 10–14 days, no chew toys, no hard kibble, no brushing over the extraction sites for 2 weeks, and prevent pawing at the mouth - an Elizabethan collar if needed. Expect mild swelling and blood-tinged saliva for 24 hours. Frank hemorrhage, swelling that worsens after 48 hours, drooling with food refusal, or a visible gap in the gum line means call immediately.
Recheck at 10–14 days to assess healing, and start the home-care plan at that visit - brushing, a VOHC-listed chew or water additive - because extractions treat today's disease, not tomorrow's.
