A root canal (also known as an endodontic treatment) is a serious procedure, but one that

specialists handle every day. Before engaging in any type of dental work, it’s important to
know the facts about root canals.

What is a root canal?

Root canal treatment is designed to eliminate bacteria from the infected root canal, prevent
reinfection of the tooth and save the natural tooth. When one undergoes a root canal, the
inflamed or infected pulp is removed and the inside of the tooth is carefully cleaned and
disinfected, then filled and sealed.

How does endodontic treatment save the tooth?

The endodontist removes the inflamed or infected pulp, carefully cleans and shapes the
inside of the root canal, then fills and seals the space. Afterward, you will return to your
dentist, who will place a crown or other restoration on the tooth to protect and restore it to
full function. After restoration, the tooth continues to function like any other tooth.

Does a root canal hurt?

Many endodontic procedures are performed to relieve the pain of toothaches caused by
pulp

inflammation or infection. With modern techniques and anesthetics, most patients report
that they are comfortable during the procedure. Therefore since patients are given
anesthesia, a root canal isn’t more painful than a regular dental procedure, such as a filling
or getting a wisdom tooth removed. However, a root canal is generally a bit sore or numb
after the procedure, and can even cause mild discomfort for a few days.

How do you know if you need a root canal?

Root canals are needed for a cracked tooth from injury or genetics, a deep cavity, or
issues from a previous filling. Patients generally need a root canal when they notice their
teeth are sensitive, particularly to hot and cold sensations. 

There are a few symptoms that mean you might need a root canal:

  • Severe pain while chewing or biting

  • Pimples on the gums

  • A chipped or cracked tooth

  • Lingering sensitivity to hot or cold, even after the sensation has been removed

  • Swollen or tender gums

  • Deep decay or darkening of the gums
