When is tooth trimming generally indicated for rodents?

• A. Always
• B. Only if there are malocclusions
• C. Never
• D. Only in exotic species care settings

Answer: (B)

Rodent incisors grow continuously, so trimming isn’t something you do routinely; it’s used only when growth has become a problem. If the teeth are properly aligned and being worn down naturally by gnawing, trimming isn’t needed and could even cause harm by removing too much tooth structure or exposing the pulp. When malocclusion or overgrowth occurs, trimming can restore proper bite and prevent trauma to the lips, cheeks, or tongue, making it a necessary, but situation-specific, intervention. It’s not limited to exotic settings, but it isn’t indicated for every case either—only when there is malocclusion or functional impairment.
