You should book a check up with a rabbit savvy vet. They can determine if your rabbit will need the teeth filed or clipped. You can also discuss with the vet what do it and how often it may need to be done.
Most rabbits do not need to have their teeth trimmed. A good diet with lots of hay will wear down the teeth and other chew toys can help with the front teeth.
If they are aligned right, then you may not need to do much other than provide good chew toys. If they are not aligned properly, then they will probably need to be trimmed on a regular basis and could end up needing to be removed.
