Hamsters Teeth problems

Hamster teeth should be yellow or brownish white.  Hamsters are rodents and therefore their teeth grow continuously.   This means that a hamster needs to grind its teeth down regularly to stop the teeth from overgrowing. Hamster does this by gnawing on something hard. Many hamsters will gnaw on the cage bars or there are wood chews available from pet shops. If a hamster had nothing to gnaw on to file down its teeth, the teeth may overgrow and could puncture the mouth or jaw.

Abnormal conformation of the teeth can sometimes occur for congenital reasons, affected family lines should not be bred from. Hamsters are one of the few animals born with fully developed teeth.

Their teeth can be knocked out on impacted during a fall too.  This is bad because hamster teeth are not rooted the way a human's teeth are, there is probably no way to save the tooth. If it was an incisor that was knocked out, the hamster may have an awful time eating and will have to have his teeth clipped regularly as with the maloccluded teeth.

You should inspect your hamster's teeth regularly.  If they are getting too long, the hamster will not be able to eat properly.  Also there is a condition called malocclusion which is an inherited misalignment of the teeth.  A hamster can die from starvation with this problem, but there is also a risk that the teeth themselves will grow until they penetrate the skull, killing the hamster.  

The teeth in this case need to be clipped.  A vet can trim them for you.  If your hamster has maloccluded teeth, you will have to have this done regularly, about every other week, but you should check his teeth routinely when you clean his cage.  The vet can show you how to trim their teeth by using a nail clippers or nippers to keep the teeth at the right length.

Do not feed your hamster sweets meant for humans and limit the amount of sweetened hamsters treats as they are not good for hamster molars.  Sticky foods can gum up the teeth and cheek pouches and cause problems.
