She may be able to manage ok at the moment, they grind food with their molars, but once the top teeth grow back the bottom teeth will most likely cause a problem, she may not be able to eat properly then as the teeth will be misaligned & also the teeth may not wear down properly any more.
I would strongly advise against clipping any teeth yourself unless you've been shown how to do it by a vet, it's a procedure that carries risks, you could break the teeth off, the teeth could split & damage the roots which would lead to even more problems.
It really would be best to get her checked by your vet, she may need regular clipping or burring now the bottom teeth are no longer aligned.
