Seeing a rotten tooth but not mine?

um.. so I basically know that teeth dreams can be either very good or very bad depending if their rotten or not but my dream is kinda confusing. well the part where there was teeth involved went something like this... it was kinda in a video game-esque world with chambers, knights and dragons. me and my fam were in this one chamber trying to get out (I ume it's the climax of the dream) apparently to get out we had to collect a rotten tooth (maybe a baby teeth) with my fam/friend's name on it. Now the tooth isn't falling out of their mouth or anything it was just there with names carved on it...and before I woke up I was freaking out cuz I couldn't find my mom's >.>.....what does this dream mean?? (please dont put it's only a dream ****...I'm generally curious to what it means 8D)
