Cat has swollen lower gums (Picture included) Very Scared

She does not seem to react when I touch her gums. She was hurt a few years back and broke a few teeth. Could this be an infection or something worse? I am going to the vet Monday but really want some advice before hand.  Im so nervous

Looks like stomatitis, however is lacking the very red color that indicates complete irritation and inflammation.

She also needs a teeth cleaning.

It can be other things too, how old is she?

Thank you. I am bringing her to the vet Monday. Do you think they will have to pull all of her teeth?

She is 10 years old

I am wondering if it could possibly be Gingival Hyperplasia? Seeing as it is not red

Absolutely yes. 

I'd love to see more mouth pics, please remember I am not a vet and am giving my opinions based on my experience as I have seen and dealt with in my cat rescue group and/or my experience working with the Humane Society.

I have some education through UC Davis medical teaching school as well that I use in rescue too.

But knowing you are seeing a vet on Monday, I'm okay with giving my opinions to help get you through until then

Any chance of getting more pics?

I greatly appreciate your input. She wont really let me get in there just a side view. I did get a quick look in the mouth earlier and I am pretty sure I saw the tip of the tooth sticking out in there. I read online that Gingival Hyperplasia can cause gums to get "tall" and she has that. Im just praying it is not tumor.
