Cases we see.
Explained plainly.
Each section pairs the actual radiograph or intraoral photograph with a plain-language clinical explanation — the same conversation we have with referring veterinarians every day.
Periapical lucency confirms pulp necrosis — extraction indicated
The Tooth You Almost Missed
See this dark line running from the crown toward the root apex? That's a slab fracture on the upper fourth premolar — the carnassial. It looks like a minor chip on exam, but the pulp is exposed and the tooth has been dying for months.
General practice extractions often leave the palatal root behind. We use a surgical microscope and intraoral radiographs at every stage to confirm complete removal and rule out periapical pathology before closure.
Bone loss >50% root length — surgical periodontal therapy vs. extraction
Stage III Isn't a Cleaning Problem
At Stage III, bone loss has already consumed more than 50% of the root support. A polish and scale won't reverse this. The question is which teeth are salvageable and which are causing occult pain your patient can't tell you about. We probe every pocket, radiograph every root, and stage each tooth individually. Owners often say their pet "started eating again" post-op — because they didn't know it hurt until it stopped.
Root replacement resorption — crown amputation protocol appropriate
The Cavity That Isn't a Cavity
Type 2 feline resorptive lesions show root replacement resorption — the body is actively converting tooth structure into bone-like tissue. These are not caries. Attempting standard extraction shears the root and leaves fragments.
We identify lesion type radiographically before every extraction. Type 2 lesions are managed with intentional root retention and crown amputation — a technique that eliminates pain while avoiding iatrogenic fracture.

If your veterinarian has recommended extracting a tooth and you want another perspective, we offer consultation appointments with intraoral radiographs and a written treatment plan. Extraction is sometimes right. But not always.

Full-mouth extraction with documented post-op protocols, adoption-ready dental reports, and volume scheduling for multi-cat intakes. We've helped cats that cycled through four foster homes find permanent placement after resolution.
