I floss my sons teeth when needed, if they cooperate for brushing teeth it is very similar.
Thanks everyone. As of right now I’m just attempting to floss, brush good and even use a wet rag sometimes to try and loosen it up. Of course the spot that I need to floss the most he doesn’t cooperate. Definitely time to go to the dentist soon.

That happened to us before... I just had to leave it alone until it shifted and was visible enough to slide out the piece of food from under the gum.
