Summary
# Editorial Summary: Equine Dental Floating (Crown Odontoplasty) Dental floating and occlusal equilibration rank among the most frequently performed procedures in equine practice, yet the anatomical basis for conservative approach remains clinically significant given the limited reserve crown available to cheek teeth. Earley and Reiswig emphasise that occlusal irregularities—including prominent cingula, transverse ridges, and enamel points—play functional roles in mastication and tooth longevity rather than representing simple defects requiring removal. Since equine cheek teeth possess a typical functional lifespan of 18–25 years with minimal reserve crown, overly aggressive floating risks premature pulpal exposure and tooth loss, making a thorough oral examination the cornerstone of any treatment plan. The authors advocate for site-specific odontoplasty guided by individual tooth evaluation rather than blanket floating protocols, ensuring that any tooth structure removal directly addresses identified pathology or functional compromise. For practitioners, this reinforces the clinical importance of diagnostic precision before instrumentation—systematic examination should precede intervention to preserve dentition and extend functional life across the horse's working years.

Practical Takeaways
- •Conservative approach to tooth floating is essential—remove only necessary structure given the 18-25 year functional lifespan and limited reserve crown in equine cheek teeth
- •Perform thorough individual tooth evaluation before treatment to develop a specific diagnosis and site-specific treatment plan rather than routine occlusal equilibration
- •Quality oral examination is the foundation of equine dental care and should guide all subsequent treatment decisions
Key Findings
- •Odontoplasty (floating and occlusal equilibration) is the most commonly performed procedure in equine dentistry
- •Equine cheek teeth have an average functional lifespan of 18-25 years with limited reserve crown available
- •Irregular occlusal surface, prominent cingula, transverse ridges, and enamel points all affect cheek tooth function and longevity
- •Site-specific odontoplasty based on individual tooth evaluation and diagnosis is recommended over routine floating
