I wouldn't worry, most likely it's just the baby teeth being worn down, getting ready for those adult teeth to pop in. Jack's teeth that I found were worn down looking, at first I didn't even recognize them as teeth they were so odd looking.
If you're diligent about brushing, and get her teeth checked by her vet with annual check-ups, chances are all of her teeth will be with her until she is an old girl.
