Cold Sensitive Teeth/Replacing large fillings in So.O.C.
So, when you eat ice cream, or drink a margarita, one of your molars, or maybe even a bicuspid, is sensitive. So, you take that problem tooth to your friendly, neighborhood dentist, and he says you need that tooth capped (or crowned). What’s that about? When you drill on a crystalline structure, like glass, or porcelain, or tooth enamel, the heat of friction from the drilling device puts microscopic fractures in the material. When we have to put a big filling in a tooth, those little fractures pre-dispose the tooth to further fracture, virtually splitting the tooth, in subsequent years. Later, after years of chewing trauma, the nerve becomes irritated from this microscopic splitting during chewing. This hypersensitivity is usually manifested as temperature sensitivity. Just replacing the filling doesn’t really help because the cracks are already there. A crown, on the other hand, holds the tooth together, like the band on a barrel, so the splitting activity stops.
