Knowing if you need a root canal requires retreatment may require an experienced eye. This is because even people who don’t need root canal therapy frequently experience various symptoms, forcing them to think about retreatment. Opposingly, root canal infection has some lesser-known signs that only your dentist can identify.

It is essential to get familiar with symptoms and warning signs of root canal infection. This can help you act timely and prevent future damage.

5 Most Common Root Canal Infection Symptoms

Teeth Pain 

Infected root canals cause minor pain as the inner tooth material is extremely sensitive. In some cases, the dental infection thrives, leading to a dental abscess. If the tooth pain becomes unbearable, and it must be treated as soon as possible. However, not all kinds of tooth pain are linked to the root canal.

Just because you’re a victim of severe tooth pain, that doesn’t mean a root canal treatment is waiting for you. And sometimes a tooth requiring a root canal doesn’t hurt at all.

The key is to determine the type, duration, and site of the pain. It is also important to diagnose if the pain is dull or sharp and severe. The pain can exist for weeks or even months, causing continuous discomfort. While most patients can identify which tooth actually hurts, for some, an examination by a dentist is required.

Here are some types of pain that often indicate a root canal infection:

  • Sharp tooth pain when chewing
  • Throbbing tooth pain stopping you from sleeping at night
  • A pain that occurs when pressure is exerted the infected tooth
  • Hot or cold sensitivity
  • A lingering toothache

Swollen and Tender Gums

Swelling is another symptom linked to root canal failure. It comes in different types and forms. In some cases, it can look very normal and is accompanied by gum tenderness. Other times you may see or feel a big lump. And when it turns severe, you may experience a swollen face or neck. It often comes along with a toothache. Just like tooth pain, the swelling doesn’t always indicate an infected root canal.

Bad Breath 

Bacteria can cause many unpleasant-smelling infections, including infection of the root canal. If the tooth enamel gets damaged from erosion, cavity, or trauma, harmful bacteria can easily hop into a root canal and start cultivating, emitting a foul odor.

High Fever

Temperature over 99.5 degrees is one of the most common infection signs after a root canal treatment. If you have such a fever after dental work, contact your endodontist or dentist immediately.

Tooth Discoloration

A discolored tooth is one of the most prominent symptoms of a root canal infection. If you notice a dark blue, gray, or yellow toned tooth, an infection might be present. The good part is that such a tooth can be identified with ease. It has darker shade compared to the rest of the teeth.


Though the human body can effectively fight off oral infections, it is nearly impossible to get antibodies deep inside a tooth. This is where the dentist comes to rescue. If you are experiencing any of the symptoms mentioned above, be sure to contact your dentist immediately.
