Inside of mouth discolouration

I have an adult beardie around 2-3 years old with previous ill health from former bad owners (gut parasites and malnourishment) all of that is cleared up now and he seems healthy.
My one concern is I have noticed he has some dark patches inside his mouth and I have heard that mouth rot is something they can get.
He is eating fine and very active at the moment, gets natural sun every day alongside his UVB lamp. His enclosure is kept at the appropriate range and I keep him regularly bathed.
Currently I’m feeding him on an alternating diet of bok choy leaves, kale, mealworms and crickets with some occasional cooked yellow squash and butternut pumpkin.
I’ll attach images of his mouth to this inquiry where you can see the darker patches. Hoping it’s just his particular colouring considering these patches are fairly symmetrical on both sides and he seems fine otherwise.

If he is eating well then it doesn't sound like it's bothering him much. It may just be natural coloring but I can't see too clearly in the photos. You could try using an oral cleanser like MaxiGuard gel to clean along the teeth and gums if you want to. It probably isn't a big issue if the gums don't look like they are shriveling or if you don't see any open wounds etc which could indicate infection or decay.

Hi there,

I agree with cooper. In the presence of a lack of other issues, I'd say it's not symptomatic and nothing to worry about. But do keep an eye on things and let us know how things are progressing.

Ok that’s good to know. I was mainly concerned about it because he wasn’t in a good way when I first got him last year since his previous owners didn’t know how to care for a reptile but considering he doesn’t seem bothered by anything when he eats and there’s no visible wounds it’s probably just the coloration he has.
Thanks for the second opinion here ?
