My hamster's tooth is white and he's biting the cage. Should I worry?

Hi I have a Syrian hamster who is probably 8 months old. Yesterday I noticed that one of his bottom teeth became white, and the rest of teeth are yellow as usual. I am sure he had all teeth yellow before. Should I be concerned? He bites cage bar crazily these days even I provide him chewy toy. I am worried about if this is a sign that he hurts his teeth?

Thanks for reaching out about Zhuzhu. This could be a sign of lack of enamel (cause of yellow) or a possible fractured tooth and tissue is necrotic. Monitor appetite and weight, try to restrain occasionally and observe teeth. Good luck.
