Kitten with tooth resorption?

My cat is about 8 months old. When he was about 6 months old, I took him to the vet because I noticed blood on something he had been chewing on and his gums were swollen. The vet told me he had tooth resorption. Here's the thing though, my cat chews on EVERYTHING. Plastic blinds, card board boxes, my desk, books, the list goes on. Is this common with this disease? It seems to me that he should be in pain and not want to chew on rough surfaces. The vet I went to is one I haven't really been to before this cat and I'm wondering if there's any chance he misdiagnosed my cat.

Any thoughts on the likelihood of misdiagnosis? Or on how to stop my cat from eating everything?

I've never heard of tooth resorption in a young kitten.  That is something that happens with adult cats.  All of a kitten's baby teeth are deciduous and will fall out when their permanent teeth come in.  The deciduous teeth begin to fall out and be replaced by permanent teeth starting at around 11 weeks of age. By 4 months, all the permanent incisors are usually in place. By 5 months, all four canine teeth are in place. By 6 months, all 10 premolars are in place.  Kittens don't have molars, but these come in during late kittenhood or early adulthood.   Teething kittens DO chew on everything, and I suspect he just chewed too much and his gums got a little swollen OR one of his last deciduous teeth came out then and left a little blood.  Perhaps some of the baby teeth looked like adult teeth do during tooth resorption, but I suspect she did not take into account the age of the kitten and the fact he is at the end of cutting his adult teeth and losing his baby teeth.  There is no way to know for sure now, two months later.  However, it IS a painful condition and I seriously doubt he would be chewing on everything if he had it.

If you are not comfortable with this vet, you may want to see if there is an AAHA acccredited hospital in your area.  Everyone here who has been to one of these hospitals seems to be very pleased and impressed with their vets.  Check out the link below where you can search your area for AAHA hospitals.

He still regularly bleeds when he chews on things and his gums look really bad still so I'm thinking there might still be something wrong other than teething a couple months ago. Thanks for the AAHA recommendation though! The closest vet I trust right now is 30 minutes away which is a long ride for a cat. I'll definitely look into that for finding a second opinion.
