You may not experience symptoms and still require a root canal. An infected tooth that doesn’t cause pain likely means that all the nerves in the tooth have died.
If there is infection present, a root canal is necessary. Without a root canal, infection can spread beyond the tooth into other parts of your body like your gums and jawbone.
Failure to undergo a root canal when you need one increases your chances for tooth loss and other serious complications, such as:
Infection
Jawbone damage
Stroke
Sepsis
Heart Disease
