Etiology: Malocclusion occurs when the incisors overgrow because the mandibular and maxillary teeth are not normally aligned and do not properly occlude.
Incidence: The incidence of malocclusion is common.
Clinical signs: Mice may have a poor body condition and evidence of poor growth. Incisors are overgrown and misaligned.
Diagnosis: Malocclusion is readily diagnosed by an oral examination.
