Need help to figure out what's wrong with my bearded dragon

I have had my bearded dragon for 6 years now and she has a lip problem, we were told by the vet it was gingivitis so we treated her with antibiotics.
It never got better, we bath her 3 times a week and let her run around the house freely.
She eats fine, but it is painful and annoying her but I can't find a way to get rid of it.
Any suggestions?

Poor thing, that looks quite painful. He has mouth rot , which can encompass several different types of infections, trauma, etc. Your vet may not know how to handle this [ and this can be deadly, so it's serious ] so be sure to look for a qualified reptile vet ASAP. If you need help locating one, list the area that you live in and someone here can recommend a vet. Please list the exact type + brand of lights you use as well as the temps. throughout the tank and how you measure the temps. .

In the meantime you can put raw [ unpasteurized ] honey on it which is a powerful antimicrobial and may help ease the swelling + infection but is not a cure. Best wishes for your baby !

Yeah that looks like stomatitis and is probably pretty painful. An experienced vet may be able to remove infected tissue and prescribe medication as needed. In the meantime using the raw honey or an oral cleanser like MaxiGuard is a good idea to keep the area as clean as possible and keep the infection at bay.

Awe, the poor thing, it's definitely Mouth Rot, and a bad case of it, which is not your fault, that vet didn't know what they were talking about. This will only get better by taking cultures of her mouth and sending them off to determine what type of microbe is causing the infection, and getting her on the proper Antibiotic/Antifungal, both orally and probably by injection and then also a topical application in and around her mouth. You need to find an experienced Reptile Vet/Specialist to treat this, as it's extremely serious, and yes, she's in a great deal of pain and need some pain medication as well, because it's inevitable that she will stop eating soon...

If you need help finding a proper, experienced Reptile Specialist, please just let us know where you live and we can find the closes one for you, but please don't wait any longer to get her in, I'd even call them and tell them it's an emergency, and explain how the first vet was not a reptile vet and misdiagnosed "Mouth Rot", and now she's very much worse than she was, and needs to have cultures done immediately. If it isn't treated properly soon, the infection is going to spread to her bloodstream and cause sepsis, which is fatal. Mouth infections can also spread to the heart and caused Endocarditis, which is an infection in the heart, which is also fatal. So this is very urgent.
