Bloody mouth/ Lower Jaw sunken in

My 7 month old bearded dragon has started to develop an odd growth, his lower jaw is growing asymmetrical, one side more protruding sideways than the other. His upper jaw looks completely normal, but it is sticking out about a centimeter from his lower jaw. His mouth is basically open all the time now, and today I noticed dry blood on his lower lip. He opened his mouth and his two bottom front teeth seem extremely long. I’ll be taking him to the vet ASAP but is this anything someone has heard of before?

That sounds like it could be a serious issue. A vet visit is definitely a good idea. Can you provide details about his setup? What are the temps in his tank? What are you using for lighting? What is his age and typical diet?

If you can provide photos that may be helpful as well. You can upload photos here https://www.beardeddragon.org/useruploads/ and post them to your thread using the XIMG button when you reply.

Oh my, that sounds very serious. How old is he now? This is either an extreme case of MBD due to inadequate UVB/UVA light, poor diet, and/or poor supplementation, or it's some type of genetic developmental issue or an injury that was never treated and has caused improper healing. I myself have never heard of such an extreme issue, but if you could post photos of him it would be quite helpful, maybe it just sounds more drastic than it actually is.

In addition to photos of him and his issues, could you list what brand/model/wattage/type (tube, compact, coil, or mercury vapor) UVB light he has? Is the UVB light on top of a mesh lid or obstructed by any plastic covers on the fixture or by glass? How old is his UVB? How many inches is it away from his Basking Spot/Platform? How often do you give him Calcium and Multivitamin supplements?

Have you had him his entire life, since he was only a couple of months old, or did you adopt him/buy him at an older age? Did he look normal when you got him? I'm just wondering if he had an accident while with a prior owner that was never treated and allowed to heal "wonky".

I'm sorry this is happening, but it does sound quite serious, hopefully it is not painful for him. Definitely find only either a Certified Reptile Vet or a very experienced Reptile Specialist Vet, no general vets or "exotics" vets for this one, you need a vet with lots of Bearded Dragon experience.
