I don't think that it's a problem unless she doesn't drink enough water. If this is the case then she can become dehydrated or even develop a urinary tract infection. I would try to mix a little bit of wet food in with the dry food that she likes and also add a little bit of water to it. Hopefully in time she'll get used to eating some wet food and she'll learn to like it. All of my cats like wet food but some of them can't eat too much of it or they'll throw up because they eat it too fast. Good luck.
