[2] Elodontoma [3] This condition is not uncommon in degus, caused by tumour-like overgrowth of the molar tooth roots into the nasal passages. May be unsymptomatic until sinuses and nasal cavity are impacted. Typically congenital and may be associated with molar malocclusion (see above). Root elongation can also be caused by improper calcium:phosphorous dietary balance188 . [4] Do not breed from degus with a history of elodontoma or molar problems. Check the molars regularly and if necessary ask your vet to x-ray the skull to check molar roots. Check the calcium:phosphorous ratio of your degus' hard feed. [5] POOR to FATAL [0]
