The statement 'Rodents incisors will NOT grow back' is true or false?

• A. True
• B. False
• C. Not sure
• D. Depends on species

Answer: (B)

Rodent incisors are continuously growing teeth. They’re open-rooted and maintain function by ongoing eruption throughout life, so if they’re worn down or trimmed, they will elongate again as they erupt. That’s why saying they will not grow back is false—the teeth are designed to keep growing to preserve gnawing function. (Note: if an incisor is completely lost, there isn’t a replacement tooth to grow in, but the remaining incisors still persist and continue to grow.)
