“…1,4,5 The incisors of all rodents are elodont, meaning there is constant tooth formation and eruption. [3][4][5] There is one reported case of a beaver receiving a metallic bridge fitted to one maxillary incisor tooth following loss of the opposing tooth. The most frequently reported treatment for rodent incisor tooth abnormalities consists of regular shortening of teeth (odontoplasty) that have elongated due to deficient attrition from lack of substrate for gnawing or following loss of an opposing tooth.…”

“…1,2 Loss of one incisor tooth results in elongation of the opposing tooth, inevitably impinging on and injuring the oral or facial soft tissues. 4,5 Extraction of overgrowing teeth often provides a permanent solution, however the procedure is difficult in larger rodents. In small captive rodents, treatment by repeated crown reduction (odontoplasty) or extraction of the offending tooth is usually effective.…”

A 52-month-old Canadian beaver was presented for treatment of lip trauma resulting from overgrowth of the right mandibular incisor tooth following earlier loss of the right maxillary incisor tooth. Extraction of the affected tooth was considered, but rejected due to the length of the embedded portion of rodent mandibular incisor teeth. The lip injury was managed by crown reduction (odontoplasty) of the overgrowing incisor tooth pending a more permanent treatment plan. A 2-cm apicoectomy of the right mandibular incisor tooth was performed to arrest growth of the tooth when the beaver was 82-months-old. The remainder of the tooth continued to erupt and was completely expelled during a 9-month period with one additional odontoplasty being required. The beaver continued to feed normally with just the left maxillary and mandibular incisor teeth until its death at 118-months, with odontoplasty performed twice on the remaining incisor teeth during the 30-months following exfoliation.

“…Various anaesthetic regimes for both beaver species have been described [e.g. Greene et al, ; Ranheim et al, ; Kim et al, ], these vary according to required duration and depth of anaesthesia. Injectable anaesthetics may have the advantage of minimising handling stress but are associated with longer recovery times and therefore potential welfare risk of returning animals to enclosures with water access.…”

Captive care and welfare considerations for beavers

Beavers (Castor spp.) tend not to be a commonly held species and little published material exists relating to their captive care. We review published material and discuss husbandry issues taking into account the requirements of wild beavers. As social mammals with complex chemical communication systems and with such an ability to modify their environments, studies of wild counterparts suggest the captive requirements of beavers may actually be more sophisticated than generally perceived. Common field techniques may have practical application in the captive setting. Their widespread utilisation in conservation, including reintroductions, translocations and habitat management, also requires components of captive care. As welfare science advances there is increasing pressure on captive collections to improve standards and justify the keeping of animals. Conservation science is increasingly challenged to address individual welfare standards. Further research focusing on the captive care of beavers is required.
