How do you make your hamster chew its toy?

There Is actually no way to make your hamster chew a toy, if your hamster feels its teeth need to be trimmed they with start chewing things. Hamsters often chose to chew on the Bars of the cage as it grinds their teeth really quick. I have got 2 Syrians and a Roborovski Dwarf, only 1 of the Syrians decide to chew. Eating their food also grinds their teeth down from time to time.
