When tooth decay gets into the nerve of the tooth, it contaminates the nerve with bacteria, causing pain and infection. The only way to solve this problem is to remove the infected nerve from your body. This can be done by either extracting the entire tooth or simply removing the nerve from the tooth, disinfecting the inside of the tooth, and placing a filling material in the root. This is known as a root canal procedure.
With modern developments in dental anesthetics, most root canals can now be performed pain-free. We now use tiny motorized files that allow us to clean the inside of the roots of your teeth better and more efficiently.
After a root canal procedure on a back tooth, it is recommended to place a crown over the tooth to protect it and keep it from breaking. When it comes to front teeth, many times they can get by without having a crown placed, depending on how much natural tooth structure you have remaining.
