Does rabbits' front teeth grow constantly?

They never stop growing. EVER!!!

Rabbits are monophydants so their teeth grow for their entire life. However I do not think this is the question. Rabbits teeth will grow so long that they will not be able to eat if they are mis-aligned (rabbits wear their teeth down as they eat) if they are mis-aligned they CAN even grow so long that they will grow thru the roof of the rabbit's mouth and into their brain and kill them. It is not a pretty sight which is why you should keep rabbits with poorly aligned teeth clipped. This rabbit should also be culled from the herd as you will have to clip every couple of days and this is a hereditary trait (85% of the time) and not an injury (15% of the time.) more than likely.
