Infection After A Root Canal?

Updated: Jul 25


We at Evershine Dental Clinic recommend root canal treatment to patients with a cavity that has a dying root. This usually causes pain or tooth sensitivity. A root canal is necessary when there is a tooth with decay that has reached the pulp of the tooth.


When do you need a root canal?

The following symptoms will trigger for a root canal

  • You have severe tooth pain, especially when you chew or bite

  • You notice a small, pimple-like bump on your gumline

  • Your gums are red, swollen, or tender around a particular tooth

  • You are experiencing tooth sensitivity to hot or cold foods or beverages

How is a root canal performed?

When tooth decay gets deep into the pulp of a tooth, you will need a root canal. During root canal therapy, we apply local anesthesia to numbs the tooth being treated. Dentist at Evershine, drill through the crown of your tooth until we reach the pulp. Dentist cleans the area and then removes the pulp. After the tooth is clean, dentist uses gutta-percha to close the top of the crown. A temporary filling is placed there until a crown is custom-made to fully restore your tooth.


Signs of infected root canal tooth

Some common signs of a root canal infection include:

  1. A recurring pimple on the gums: This abscess may release pus or fluid.

  2. Lethargy: Feeling run down is normal after a root canal. However, if your energy doesn’t bounce back after a few days, contact dentist at Evershine Dental immediately as it can be a sign of an infection.

  3. Fever: Any temperature over 99.5 degrees may signal that you have a root canal infection.

  4. Severe pain: When you have pain that persists for a few days after a root canal, you should return to our dental clinic.

  5. The area around the tooth feels hot: An infected area often feels hot.

What causes a root canal to get infected?


There are several reasons why a tooth may become infected after a root canal. The shape of your root canals can be complicated, making it hard to clean and disinfect fully. Your tooth may also have extra canals that may have bacteria that are reinfecting your tooth. If there was a delay in placing your crown, this also allows harmful bacteria to get back into the tooth. During dental check-up, dentist at Evershine Dental can determine the cause of your root canal infection and offer root canal infection treatment.


Tooth decay spreads fast when left untreated and can lead to serious symptoms.

When you’re experiencing these symptoms, it’s important to schedule an appointment quickly with our root canal specialist.
