input: [1] Incisor teeth are long, growing into the soft tissue of the mouth, causing mouth ulcers and lacerations. Difficulty eating, painful mouth. [2] Incisor growth [3] Teeth are continuously growing, but are worn down when the degu gnaws and eats. This condition can occur if the degu is not wearing down their teeth properly or if an opposing incisor is missing. Incisor overgrowth can also occur if the molars are overgrown (see molar malocclusion). [4] Always provide wood or branches to gnaw on and a selection of dried food/treats sparingly. Check teeth regularly for growth/damage. Trim long teeth with clippers (this should be done by a VET). Bathe sore tissue with saline solution daily until healed. See details below for molar malocclusion. [5] GOOD [0]
