Sheds lower jaw frequently

[Missi]

For some reason Jim seems to shed his lower jaw and neck more than the upper jaw and head . This started in spring when he came out of his slow down . It seems like the bottom jaw is getting slightly longer than the upper .
It is not really a big difference , just a little off when viewed from one side .

What is your diet and calcium schedule like, what uvb light do you use and what's the age of it?
I don't know about the shedding more but an underbite can be a symptom of MDB.

Jim is 19 months old 22 in long and weighed 628 g in june/july (and 650g today) .
JIm gets calcium 2x per week and vitamins 2x per week .
He has a repti sun 10.0 which was replaced in June/july .
He was / is having some issues with hard urates so I was told to cut down on the calcium , which has helped a bit .

Is he still eating a lot of insects?
Maybe if you share a picture some of the more experienced member can help.

a little hard to see with the shedding.But the side of his mouth stick out a bit further than the top .He does still get insects at least every other day , supers , butter worms & hornworms are his favorite but he will also sometimes have dubia , silk worms or a wax worm here and there . His main green is collards with whatever frish fruit / vegies I have .I always make sure it is on the approved food list first .
