Most people don't know this, but teeth expand and contract with temperature. If a tooth with a filling expands, the filling can come loose and let in food and other debris. Dr. Michael Manhard of Carlsbad Dental Excellence has spent his 30-year career considering details like this. In solving this particular problem, he repairs patients' cavities with glass ionomer, which expands at the same rate as the tooth, and then puts a tooth-colored composite on top to disguise it. He's extremely thorough, not only with this procedure, but also with each of his general, restorative, and cosmetic services.
