My cat's name is Gimli, he just turned 1 on March 20th. He is a short haired cat. 
He has had gingavitis or/and stomatitis since he was a kitten. Gums have always been inflamed and red and he has had blisters in the back of his teeth for a long time.
He has a baby tooth still intact behind his adult k9. I am going to have it removed within the month and probably have a dental cleaning.
Gimli eats nutro natural choice wet food and natures variety raw kibbles in chicken. He has been on this diet for at least 6 months. He is doing very well with this, after going through some trial and error with food. 

His vet didnt really give me an answer to his ging/stom. He basically said he needs to do an xray to see if there is inflammation in the root before he decides to pull any teeth. He does really bad with steroids and antibiotics since he gets diarrhea. 
I am using tropiclean gel to clean his teeth and I am using llysine (500mg) again in this food. He is not in pain or drooling. He loves his food and always eats it all up. He also like biting on cardboard.

What do you guys suggest? Should I get the xray before getting his tooth pulled so he doesnt have to get teeth pulled on multiple occasions?  When I clean his teeth I feel the bumps in his mouth. I just want more opinions not sure if i should visit another vet.

Thank you guys!

Juvenile stomatitis that persists into adulthood has a poor prognosis; rarely is it due solely to periodontal disease/calculus accumulation, or infectious disease, as it started young and persisted.

Xray is used for an extraction anyway, as there is no way to know if the root was fully removed from the bone without Xray. With soft palate inflammation at the back of his mouth too, he may not even respond to steroids with that degree of inflammation.

Finding the root cause before extracting the majority of his teeth is ideal, but many stomatitis cats have a full mouth extraction procedure, WITH a Board-Certified Veterinary Dentist, as this is risky, involving prolonged anesthesia, nerve pain, and very delicate mandible (jaw) structure than regular vets have fractured too many times to be worth saving money using a regular family vet for extensive extractions.

He should've already been tested for FeLV/FIV as he's an adult. Both diseases can cause stomatitis secondary to poor response of WBC's to bacterial infection. If negative FeLV/FIV status, a tissue biopsy can confirm if he has immune mediated disease causing his stomatitis, such as EGC or early onset cancer. If biopsy isn't an option before his anesthesia, your vet may empiracally try steroid, antibiotic, and even cyclosporin (Atopica) to knock out the inflammation before his anesthetic event. If little to no effect, or trouble with oral meds in a painful mouth, they may recommend referral to the boarded dentist.

If they want to tackle full mouth extractions themselves, just ask for their experience doing so many extractions in one patient in one sitting, if they have digital Xray to confirm all the roots are removed (very important), and why they wouldn't elect to refer you to a specialist (what's the advantage/risk of this recommendation?)

Hope he's on some good pain management as stomatitis is uber ouchy. Good luck consulting with your vet about his cause and treatment!
