If your tooth is traumatized or gets a cavity that is allowed to grow large enough that your tooth gets infected, a root canal treatment is often the only way to save your tooth.
Inside you’re the hard enamel outer shell of your tooth, are blood vessels, lymph vessels, and nerves. A root canal cleans out the infected nerve chamber and repairs the damage. The chamber is then sealed off inside the root of the tooth so that the socket around the tooth can heal. Once the body clears out the infection, the pain subsides, and the tooth and socket feel normal again.
After the root canal is completed, the tooth needs to be restored with a ceramic cover called a crown. This helps to prevent the tooth from breaking or splitting apart. Once the crown is completed, the tooth can function and feels like a normal tooth again.
