[QUOTE="Inman Labs, post: 13288, member: 318"] Acrylic shrinks away from the wires always.. When the patient swallows it can draw saliva into the space between the acrylic and wire, this is called capillary action or effect. It sure looks like rust and I guess it really can be rust but if you ever remove the acrylic and expose the wire this so called rust usually just wipes away... I think the "rust" is often just goo suspended in the moisture between the wire and the acrylic but it sure looks bad! Regards, Don [/QUOTE]
