Cat growing permanent fangs without losing baby teeth

Retained deciduous teeth happen when permanent adult teeth erupt before the baby teeth fall out, creating a double row of teeth. This can cause the new teeth to grow in misaligned positions and trap food or plaque, making a veterinarian visit necessary to extract the baby teeth and prevent dental crowding.

“He's 4 1/2 months old and scheduled to be fixed in a month. Consensus seems to be that they should fall out on their own or they'll remove during his surgery, right?”source ↗
