Dental Disease, a Mobile Canine, and an Owner Who Refuses Extractions
Buster is an 8-year-old, 6.8 kg male neutered miniature schnauzer presented for 'a dental' because of halitosis and dropping food. On oral examination under light sedation, you note generalized gingivitis, grade 3 periodontal disease of the right mandibular canine with 5 mm probing depth and grade 2 mobility, a fractured right maxillary fourth premolar with exposed pulp, and heavy calculus. The owner says, 'Please just clean his teeth; I can't afford extractions or x-rays.' Preoperative blood work is unremarkable except ALP 310 U/L (reference 20–150). The clinic's dental suite has a wall-mounted digital dental unit, a charting form, and a heated recovery cage. The veterinarian asks you to help obtain informed consent and prepare the treatment plan.
1. Explain why dental radiographs and periodontal probing are essential before agreeing to a 'cleaning only,' and what specific findings would change the plan.

A visual 'cleaning' cannot determine the extent of disease below the gumline. Periodontal probing measures attachment loss and pocket depth; radiographs show bone loss, furcation involvement, root resorption, retained roots, fractures, and pulp pathology that are not visible on the crown.
In Buster, the 5 mm pocket and grade 2 mobility of the right mandibular canine indicate substantial attachment loss. Radiographs may show loss of alveolar bone, a fractured root, or a tooth that is held in place only by inflamed soft tissue. The fractured maxillary fourth premolar with exposed pulp is a painful endodontic lesion; cleaning the crown will not treat the pulp exposure. Heavy calculus also hides caries, resorptive lesions, and fractures.
Specific findings that would change the plan include:
- Bone loss involving more than 50% of the root or a furcation lesion.
- Root fracture, resorption, or retained root fragments.
- Pulp exposure with periapical lucency.
- Mobile teeth that require extraction or referral for root canal therapy.
- Oronasal fistula or mandibular bone loss that increases fracture risk during extraction.
Without radiographs and probing, the team cannot obtain informed consent for the actual procedure or plan analgesia and extraction equipment appropriately.
2. The owner insists on no extractions. How would you communicate the risks and document the conversation? Include at least three specific risks of leaving the mobile canine and the fractured premolar untreated.

Use plain, nonjudgmental language and separate the estimate from the decision. For example: 'I understand the cost is a concern. A cleaning removes surface tartar, but it does not treat the infected bone around the mobile canine or the exposed pulp in the premolar. Those are painful. If we clean without addressing them, Buster may still have difficulty eating and may develop a worse infection.' Offer a staged plan, a written estimate, and a referral or payment option if available.
Specific risks of leaving the teeth untreated:
- Chronic pain and poor eating - mobile teeth and exposed pulp cause discomfort; the dog may swallow food whole, drop food, or lose weight.
- Progressive infection and bone loss - periodontal pockets deepen, and infection can spread to adjacent teeth or the jaw.
- Mandibular fracture or oronasal fistula - severe bone loss weakens the jaw; a fractured maxillary premolar root can create a communication with the nasal cavity.
- Bacteremia and systemic effects - oral infection can seed other sites, especially in a dog with other health issues.
Document the discussion in the medical record: the specific teeth, the risks explained, the owner's refusal, the estimate provided, and the recommendation for recheck or referral. Have the owner sign an informed-refusal form. Do not perform a 'cosmetic cleaning' that leaves painful pathology untreated without a clear veterinary plan; the veterinarian should decide whether to proceed with a limited procedure.
3. Outline the immediate post-extraction and post-anesthetic nursing care for Buster, including analgesia and feeding.

Recovery and monitoring
- Keep Buster warm, oxygenate if needed, and monitor until he is sternal and swallowing.
- Check heart rate, respiratory rate, temperature, mucous membrane color, CRT, and blood pressure as ordered.
- Inspect the mouth for bleeding or swelling; a small amount of blood-tinged saliva is expected, but active bleeding, expanding swelling, or respiratory difficulty requires immediate veterinary attention.
- Provide a quiet, padded recovery area and prevent chewing on the IV catheter or cage bars.
Analgesia
Use a multimodal plan: an opioid such as buprenorphine or hydromorphone as prescribed, plus a local anesthetic block if the veterinarian performed one. An NSAID may be appropriate if renal and GI status are acceptable; check with the veterinarian before administering. Assess pain with a recognized canine pain scale, watching for drooling, pawing at the mouth, reluctance to eat, and vocalization.
Feeding and home care
Offer soft food and water after full recovery. Avoid hard kibble, bones, chew toys, and tooth brushing near extraction sites for the period recommended by the veterinarian. Give medications exactly as prescribed and explain that some drooling and mild swelling can occur. Provide written instructions for bleeding, swelling, lethargy, vomiting, or refusal to eat, and schedule a recheck. Remind the owner that extractions are treatment, not a cosmetic loss; the goal is a comfortable mouth.
