Although most dental fillings work well for many years, they are likely to eventually require thorough overhaul. Dr. Marianne Salsetti of Wappingers Falls said: “Whether it is a cement canopy or cap, or a directly placed filler material, it will break at some point.” “The gap in the restoration of the teeth may eventually open and begin. "Leakage" causes sensitivity in the early stages and declines over time," she pointed out.
Teeth are often subjected to daily pressure caused by chewing - while teeth or teeth can increase the added strength of tooth enamel and fillings. According to the American Dental Association, all of these may help to make the filling gradually brittle, crack, wear, or fall off. Bacteria can also wriggle around the edges of the filler, causing invisible injuries; eventually, it can reach the nerves, causing pain and requiring replacement of the filling - or sometimes performing the root canal or even completely pulling the tooth out.
