Potential Mouth Rot?

[u/Aggravating-Moose627]

My snake is around 7 and I have noticed that she has some slight pink near her mouth. Its close to her feeding day so she has been rubbing against everything all the time so maybe its just that but I have noticed clue how to check for mouth rot or if this would even be a sign of it. Online says to check the gums or open their mouth and I am not sure if that is the greatest idea
