Dentistry for the Veterinary Technician
Oral Anatomy and Assessment
Dental care requires knowledge of tooth anatomy, numbering, and periodontal structures. Understand the gingiva, periodontal ligament, alveolar bone, and cementum. Know the stages of periodontal disease and the difference between gingivitis (reversible) and periodontitis (irreversible attachment loss).
Dental Procedures
Technicians perform and assist with dental prophylaxis, charting, and radiography. Understand the purpose of scaling (supra- and subgingival), polishing (to smooth the enamel after scaling), and irrigation. Know the indications for extraction and the importance of dental radiographs before extraction. Familiarize yourself with home-care products and the Veterinary Oral Health Council seal.
Anesthesia and Safety in Dentistry
Dental procedures require general anesthesia with a protected airway (cuffed endotracheal tube) to prevent aspiration. Understand the risks of bacteremia, the use of local blocks, and monitoring during procedures.
Traps to Watch
Questions often confuse scaling with polishing or imply that polishing is optional. Polishing is required after scaling to remove microabrasions that harbor plaque. Another trap is assuming dental disease is cosmetic; it is a medical condition with systemic implications.
Worked Example
A dog presents with halitosis and mobile teeth. Charting reveals attachment loss and pocket depth >5 mm. The correct interpretation is periodontitis with possible extraction; radiographs are needed to assess root and bone involvement.
Rule of Thumb
Scale, then polish, then irrigate; always protect the airway and image before extracting.
