Mouth rot?

[MushuHemmi]

It looked like my Yoshi had a piece of dry salad, he likes to eat his leftovers from the day before, on his lip. I opened up his mouth and I don't know if it looks okay or not. I think the darker spot is some dry salad, but I don't want to pick it off if it's something else.

He is about a year and a half old, has the proper lighting, basking spot hovers around 100, has a salad usually every day, a few crickets a day, has the calcium and multivitamins in proper amounts, has water available at all times, is in a large DIY enclosure that's four Foot by two foot by two foot I believe, is on tile, the enclosure is cleaned once a week and poop is cleaned up when spotted.

Does it look like mouth rot? If so is it contagious? How should I treat it?

Hi there, no pics are showing up, here's how to post :

BTW it doesn't sound like mouth rot, just some stains but better safe than sorry so it's always good to check.

Here's another one. I don't think it's showing up still. I'm updating it properly, but it's not showing up. Why isn't it showing the pictures?

Now it's showing.

Looks fine, no sign of rot in that picture.

Thank you! I'm glad it's not mouth rot.
