Root Canal

Root Canal

A root canal cavity is a central space present in every tooth. It is filled with the dental pulp, which comprises blood vessels and nerves that are responsible for the nourishment and sensation. The dental pulp may sometimes get infected by the microbes, which can lead to a severe oral condition called the root canal infection. If left untreated, the infected tooth may be at risk of getting extracted.

What are the common causes of root canal infection?

Cavities: Cavities are caused due to the erosion of the enamel by the tartar deposits. When a cavity grows bigger, it can reach the deeper layers of the tooth and enter the root canal. The microbes can infect the pulp and lead to a root canal infection.

Damaged teeth: When the teeth break, crack, or chip due to external trauma, the underlying root canal cavity will be exposed to the microbes, which can possibly cause a root canal infection.

Gum diseases: Severe gum diseases, such as periodontitis, can infect the gum tissues and the surrounding teeth as well. The microbes could enter the dental pulp through the tooth root and cause an infection.

What are the symptoms?

  • Extreme pain near the infected tooth, especially while biting and chewing food
  • Bleeding and discharge of pus from the gums
  • The infected tooth may become dull in color
  • It may become highly sensitive to hot and cold foods
  • Over time, the microbes can cause jawbone deterioration
  • The infected tooth could loosen from its socket and eventually fall off

What is the treatment?

The best way to treat a root canal infection is by getting rid of the infected dental pulp from the tooth. During the initial consultation, we will numb the affected area and open an access point through the tooth's top surface. Dr. Felahy determines the working length of each canal, and then cleans and shapes to receive the filling material. 

Then, we will use an inert material referred to as gutta-percha to fill the hole. After a few days, a ceramic crown will be fabricated and bonded to the tooth to prevent it from cracking or crumbling.
