Yeah none of ours chew much (except the bar chewing lunatic lol), and the only one who chews bars started doing so really early to get our attention.
Then it just progressed to really bad levels and she's now banned from bars and chewing anything she can get her teeth on to distract herself. Even she didn't chew much before the addiction though, so I think its now that her gnawing is unhealthy to be honest, rather than before when she scarcely chewed anything.

Oh and I think if they're going to bar chew nothing will stop them. Scamp had wooden toys, a mineral block, fruit flavoured wood, fruit flavoured calcium based stuff on lolly sticks, a loofah, cuttlebone, cardboard, small wooden sticks (from multiple trees), dog biscuits, hamster-safe string woven through some of her bars... And the only thing she ever touched much was her bars. It all started to get our attention though, just managed to get into an addiction from there. Now she gnaws anything and everything but its just because she's being forced to get over the bar chewing thing.

If your hamster starts on its bars do what you can to stop them. We tried with Scamp but not as much as hindsight says we probably should have, but theres no point in worrying about them chewing bars until they start doing it to be honest.
