I'm pretty much double posting right away (sorry!) but I found a couple programs that might help you in case you haven't ran across them already.

There is the Humanitarian Animal Relief Program:

Also the St. Francis Animal Hospital might be able to point you to the right direction:

Same thing with the Central Florida Animal Pantry:

Welcome to Central Florida Animal Pantry

The Pet Fund does indirect payments for treating animals who need vet care. You have to prove income/lack of income though, and have a cost estimate (so a vet treating your dog. This would mean you'd need the funds to get your dog seen - but there is a strong possibility that they would cover the surgery and medications if necessary.) I would give them a call and talk to them about what they can do.

The Pet Fund

Do you have (or had) a vet that you used for quite some time? If you have a good report with them it might be worth a shot to ask them if they would considering exchanging your time for the cost of care.

Thanks Dame for those links. I emailed the Humanitarian one. The school one I could ask info from, but thats about it. None of those places are anywhere near me. I am in very SW florida.

I only been to my vet for lolli's spay and dental, and heartworm preventative medications every month but it is not a full vet clinic just mostly for those things so I guess the answer is no, I'm not sure.

I was pretty sure that they were no where near you, but the great thing about programs like those are that they tend to be very aware of what goes on around them. If there are programs like those near you - they should know of them or give you tips on trying to find help.

Ya, I asked the humanitarian one and stuff. I might contact the school one too if the first one doesn't respond. Thanks :P

Please don't take this as veterinary advice, because I'm not a vet.
But...
Ellie had horrible teeth problems for years and we were pretty clueless about what needed to be done. Then they started falling out. After an exam, she was put on antibiotics and we didn't get her dental for a month (after exam). Now this was a very severe case... I don't think putting off an adult tooth extraction with no periodontal disease is a huge deal. It may be painful for her...I have no idea. But maybe talk to the vet about it? It may not need to be pulled. Maybe it will just fall out. If the vet is concerned about infection, maybe use antibiotics?

Im sorry to hear what youre going through, I know the recession has hit both our countries hard.

I think you are doing exactly the right thing, keeping the tooth clean, the mouth clean and keeping an eye on it. Older dogs and cats do naturally lose the odd tooth and often there are no side effects, the socket will heal and nature will take care of itself. I had a cat that kept losing the odd tooth when he got older and I didnt take him to the vet each time, only once when the mouth looked inflamed. I was in the same position as you then, but thankfully in our country we have the PDSA and if youre on benefits you can use their vet service and just make a donation. The rules are quite strict though and you do have to take in your paperwork. Sorry thats no good to you though.

What I would do is keep it clean, keep an eye on the mouth generally, and in the meantime do a google search. You might be able to find a home remedy or a herbal remedy or self treatment for this type of complaint. There may be some over the counter medicine you can buy for it. Just do some research. Another thing is, could you use your grooming position to get in touch with a clinic and try and talk your way into some free treatment? Sounds unlikely I know, but you might have a vet or a vet nurse for clients. Or why not phone up all the vets in our area, speak to the vet nurse and ask for some free advice, they do this at our vets. You never know, they may be able to help you. ... Good luck.
