Years ago, a painful and badly infected tooth due to caries or traumatic injury was doomed to be extracted. But today a majority of these teeth can be saved by a special dental procedure called ROOT CANAL TREATMENT(R.C.T). Retaining your natural tooth helps to effectively chew and also it functions and feels like the other natural tooth. Following R.C.T in majority of cases a crown is usually used to cover the R.C.T treated tooth.
