why should the arnalgam used in dental fillings have the same average cofficient of expansion as a tooth what would occur if they were mismatched?

he reason why dental amalgam (a mixture of metals used in dental fillings) should have the same coefficient of expansion as a tooth is because the coefficient of expansion is a measure of how much a material will expand or contract when exposed to changes in temperature. If the coefficient of expansion of the dental amalgam is different from that of the tooth, it can cause problems. If the coefficient of expansion of the dental amalgam is greater than that of the tooth, the filling will expand more than the tooth when exposed to heat, and this can cause the tooth to crack or fracture. Similarly, when the filling contracts more than the tooth when exposed to cold, it can cause the tooth to become loose or fall out. On the other hand, if the coefficient of expansion of the dental amalgam is less than that of the tooth, the filling will not expand as much as the tooth when exposed to heat, and this can cause the filling to become loose or fall out. Similarly, when the filling contracts less than the tooth when exposed to cold, it can cause the tooth to crack or fracture. Therefore, it is important for the coefficient of expansion of the dental amalgam to be as similar as possible to that of the tooth in order to prevent these problems from occurring. In order to achieve this, dentists use a special type of dental amalgam that is specially formulated to have a coefficient of expansion that is similar to that of the tooth.𝘩𝘵𝘵𝘱𝘴://𝘸𝘸𝘸.𝘥𝘪𝘨𝘪𝘴𝘵𝘰𝘳𝘦24.𝘤𝘰𝘮/𝘳𝘦𝘥𝘪𝘳/372576/𝘮𝘶𝘣𝘪𝘳𝘪𝘨𝘪/

Why does it hurt when metal touches a tooth filling?

It is called Galvanic shocks. If you have a gray filling, which contains some metal, it can cause a shock when you put another piece of metal on it. This doesn't happen when you have white fillings.

What will happen if you fill pie crust with hot filling and then bake it?

Well, darling, if you fill a pie crust with hot filling and then pop it in the oven, you're playing a dangerous game of soggy bottoms. The crust won't have a chance to properly bake and set before it gets bombarded with all that steamy filling, resulting in a sad, mushy mess. So, do yourself a favor and let that filling cool down a bit before you cozy it up in that crust.
