Unerupted Teeth 1004.e3

PEARLS & CONSIDERATIONS

VetBooks.ir Comments Diseases and Disorders
• No tooth should be considered missing
without radiographic diagnosis.
• Extraction of unerupted teeth may not be
necessary in older pets (8-9 years) if there
is no radiographic evidence of associated
lesions. The odds a dentigerous cyst will
form at this age are low.
Prevention
* • Removal of persistent deciduous teeth
• Early recognition of missing teeth in young
animals
• Selective breeding
Technician Tips
Technicians are at the frontline for identifying
unerupted teeth during professional dental
cleanings and pointing them out to the
veterinarian if they were not noted previously.
