Root Canals Q&A

What is a root canal?

A root canal is a dental procedure used to address an infected tooth. To understand the process it helps to think about how your teeth are structured. 

The outermost layer of each tooth is composed of a hard tissue called enamel. Just beneath lies another layer of hard tissue called dentin. These layers protect the pulp, a soft tissue that fills the hollow inner chamber of your tooth and tooth roots. 

Your pulp is filled with blood vessels, nerves, and connective tissues that play critical roles during tooth development. As an adult, however, your pulp is no longer necessary. When the pulp becomes infected by advanced decay or trauma, serious pain can occur. 

A root canal solves the problem by removing the infected pulp, which eliminates sensation in the tooth. 

How do I know if I need a root canal?

Pain when chewing or biting down is the primary symptom of an infected tooth. Some other things to keep an eye out for include:

  • Lingering sensitivity to cold or heat
  • Swollen or sore gums
  • Pimple-like sore on gum tissue
  • Chipped or cracked tooth
  • Darkened gums or visible tooth decay

A thorough dental exam can detect signs of a tooth infection. In the case of decay, routine dental exams can often catch problems in the early stages and prevent the need for a root canal. 

What happens during a root canal?

Dr. Karren begins by numbing the area to help you rest comfortably. He then creates a small opening in your tooth to gain access to the inner chamber.

A series of tiny instruments called files are used to remove all traces of the infected pulp. Once clear, the chamber is cleansed and reshaped before a material called gutta percha is used to fill the chamber to provide structural support. 

The access opening is closed with a small filling and a custom crown is created to cover the tooth. This provides additional support and allows your restored tooth to look and function just like your natural teeth. 

At Karren Dental, the team performs the majority of root canals procedures their patients need without having to refer out to a specialist.
