UPDATE:
This is the best photo at this time for a look at some of her teeth. She is missing a front canine but it seemed best to show you all one side of her mouth. Maybe this will shine some more light on things and show you all what is going on, at least a little.
The more Mowgli and me work on other issues, such as flea care (combing difficulty as she use to have mats and some part still are a bit knotty therefore I only really comb near and around the spine) the more it becomes clear that her mouth is also causing her some pain.
Opening her mouth is not something we like to do as it stresses her out a tad and it can be difficult to open her mouth because she doesn't like anyone touching her teeth or even her mouth for similar or obvious reasons.

It's noticeable at this point while watching it get worse as I try to save up.
If you would like to help and are able to then could you possibly chip in?
Not expecting the whole cost sorted by you guys... but it would be lovely if anyone could help in any way.
Many thanks to you all
