Gingival Hyperplasia


The Boxer is the most common breed that presents to the veterinarian for gingival enlargement. Gingival enlargement could be due to either hypertrophy or hyperplasia, however, the latter is most common.  In the Boxer and other breeds, gingival hyperplasia is believed to be "familial" or inherited.  Dogs on calcium channel blockers, or on anti-siezure medications such as phenytoin; may also develop gingival enlargements.



If gingival enlargement is associated with a specific drug, changing medications may be helpful.  Periodontal surgery is typically the treatment of choice to eliminate deep pockets where bacteria can hide, colonize the periodontal tissues, and cause destruction.

This patient was successfully treated by gingivectomy and gingivoplasty.  Subsequent to gingival surgery, the teeth were brushed daily at home.  The primary care veterinarian periodically provided professional care (COHAT) with diagnostics (dental radiography and periodontal probing) to monitor these issues.
