Teeth problems

I've litteraly noticed my cats 2 teeth were lower than normal, so I checked, it's clear his gums are swollen and inflamed. The two teeth are litterally almost black by the gums. The ends by the point are  yellowish hence why I didn't notice how bad it it. And they are both wwobbly. Which feel loose enough to fall out.  I already feel bad about it not even picking up the fact that he could be in so much pain. He's Eating/drinking as normal and normal within himself but clearly he must be in so much pain by how bad they looked. My question is would this be considered severe tooth decay and will call for teeth extraction? And if he did have his teeth extracted. Does he have to have soft foods? He's 8 so definitely not baby teeth. And I know its not normal for them to lose teeth so I know that clearly theirs a big problem here. Please note I am taking him to the vet, soon as they are open tomorrow I'm booking a appointment. As I know theirs a risk of abcess/ infection.

Hello - I also have been amazed at times, how few signs of pain dogs seem to show when they have widespread dental disease.  For this reason, we often give them pain releif anyway.  You actually sound as if you're On It.   Your vet will let you know whether and which teeth need to be extracted, what your dogs' anaesthetic risk is like and will often provide a special diet after the dental.  Wishing the two of you all the best at this stressful time.

(Rereading that, your vet will prescribe pain releif if needed too - we don't reccommend that owners do that, although you sound as though you probably already understand that).

PPS:  Im sorry  - your pet is a cat!   Actually, it doesn't change very much, except that cats hide any signs of pain much better than dogs do, so please don't feel bad that you haven't picked this up before - at least you have a vets' appointment booked now.  Sometimes the problem is overgrowth of gum, sometimes inflammation of the teeth - your vet should be able to help you to come up with a treatment plan.   Wishing both of you all the best from here.

PPPS:  with my apologies the the wretched organisation of this answer, I have realised that I have not included any possible diagnoses for you here.  It is a feature of the programme that we cannot delete answers when we have written them - which is great for accountability, but not so good at times such as this.  One possible explanation for what is going on in your cats' case, is gingival hyperplasia (overgrowth of the gums, often due to inflammation) but other, including more sinister causes may need to be ruled out.  We hope that your vet is able to get to the bottom of it for you.
