Mouth infection (?)

[Lolo76]

I just went to check on Snug, my little normal 2yo boy, and he appears to have some sort of mouth infection. Now I should mention first (before mouth rot is suggested), he has ALWAYS had a problem with his "lower lip." I bred this boy's clutch myself, and from the minute he slithered out of the egg, I noticed a weird misshapen bump - right around where the egg tooth usually is, so I'm guessing it broke while he was emerging.

I have had some issues with the humidity in his tub, since he always re-arranges the furniture & puts the water over the heat strip... I'd pretty much given up keeping things 100% dry, so maybe that caused this flare-up? I will call the vet on Monday, but since it's 3am on a Sat/Sun, I'd like to hear some suggestions in the meantime. He seems otherwise fine, btw, and the inside (what I could see) doesn't look like mouth rot or RI. Oh, and he ate a live mouse about 5 days ago.



The clear "dot" has been there since hatching...




See how it juts out a bit? It's always a little oddly-shaped, but this is worse than usual.
