Gingivitis in Kittens

[amylyou]

I have a question regarding kitten dental health.

Back story:
I adopted my furr baby from a local SPCA at ~4 months. FIV negative.
Received 2/2 kitten vaccines. Otherwise I know little of his history. However,
he has been a very healthy, loving kitty with lots of energy and a good appetite.
Yesterday, Pekoe was booked for his neuter which went very well
and he is recovering quickly and is already back to his usual cuddly self today!
However, the vet noticed some reddening of his gums near his teeth.
She recommended dental xrays during his anethesia which showed an extra
tooth which she didnt seem too worried about and didnt recommend extracting
at the present time. However, she did show concern about the gum redness
and apparently consulted a specialist. She called me today and recommended
a dental surgery to remove the inflammed gum tissue and clean beneath.

From my research it seems as though she is suggesting a stomatitis (as she also mentioned extraction of all teeth may be necessary if the first surgery doesnt work)

My question is, does this sound a little, extreme.. to anyone?
I asked her about the risk benefit ratio of this surgery at the present time,
as he is showing no symptoms of distress or discomfort. She only recommendation was to get the surgery done in a month or two once he has recovered from his neuter. I feel like a more conservative option should be
tried before I put my furr baby under for (what sounds like) a pretty intensive surgery. I'm not concerned about money, my kitties health is priority.
But does anyone think an at home brushing/dental treat routine might be
a better first option?

Any advice would be great! Thanks! And sorry for the long post!!!
