A bigger cage can solve it - but it has to be big enough! Minimum 80cm by 50cm approx continuous floorspace. 3 joined cages of 60 x 40 wouldn't work. One cage of 80 x 50 or bigger is best!
I don't know what cage you have but it is common sense that if a Hamster is not happy in their environment they will try and chew their way out, no matter how many chews you give them
I would look to sorting and enriching her environment - this is the main thing that allows hamster to develop normal behaviours. If she is already in a large cage, it could be an intermittent thing that has been triggered. Our hamster has only chewed bars twice. The first time was when he was in a small rotostak set up. He was desperate to get out! The second time was after he had been in his current cage for a long time but we had been away on holiday and he had been taken somewhere else for a couple of weeks where there was a female hamster on heat. He was quite stressed for a week or two on his return and chewing the bars. This became a habit as we would open the door. So we broke the habit by ignoring him when he started doing it, turning the lights out and going to bed early. And he stopped bothering!
Nine times out of ten though it's usually because the cage isn't big enough, the wheel is too small or there isn't enough depth of substrate, or all three.
If you post a photo of your cage we can advise on possible solutions.
