My dad went into the hospital with top and bottom dentures. After his catherization he came back to his room with just top dentures?

HPotter, usually just prior to any type of medical procedure, where the patient isn't awake, the pre-op team will have the patient remove all dentures. Check with pre-op.

Done all the obvious checking. Their last response was we will check with the laundry service (off site) and see if it got taken out with his laundry. Never heard back from the floor manager (not head nurse in this case). Likely dining team took the dentures out with his food tray into the garbage.

Well they must still be there. Go see the Head Nurse on that floor and ask her to check with the cath lab.
