A root canal is required when the nerve of your tooth becomes infected. Root canal treatment lets you keep the tooth rather than have it extracted. Keeping your teeth helps prevent other teeth from drifting into the missing areas and causing jaw problems. Saving a natural tooth avoids having to replace it with an artificial tooth in the future.
After your root canal treatment, your tooth will have to be restored with a filling or crown. A restoration will be required along with your root canal treatment so that your tooth post treatment will function as normally as possible.
