All the damage done by MBD isn't usually reversible but if the calcium levels are brought back into balance no further damage will likely occur...as long as you correct your husbandry.

That being said...it needs to be determined if your chameleon even has it. I don't see any signs of it.

Mouth open could be a respiratory issue, temperatures too hot, etc.
