What happens when hamster's teeth grow too long?

This could cause many problems in eating and result in weight loss, mouth infections and things like that for the hamster :/ ofc a hamsters teeth will never stop growing so they usually chew on things like the metal bars in their cage or a bits of wood, and also hamster chews. but if your hamster is already at the point were it is too Lon you should see a vet and hopefully they can help :)

They get inaffectedand grown to their guns and too big that they can't eat either
