Causes & Symptoms of a Reinfected Root Canal

A root canal is designed to save an infected tooth and eliminate pain, but what happens when that tooth gets reinfected? 

If you’ve had a root canal in SW Calgary, understanding the causes of reinfection and knowing how to prevent it can save you from future complications. Speaking with a dentist near you about common reasons for reinfection, signs to watch out for, and treatment options available can help you be prepared in case this should happen. 

What Causes a Root Canal to Become Reinfected?

The success of a root canal relies on completely removing bacteria from the tooth and then sealing it properly to prevent future infections. However, various factors can lead to reinfection even after a seemingly successful procedure. Some of the common causes that can lead to root canal reinfection are:

• Incomplete Removal of Bacteria

Despite the dentist’s best efforts, bacteria may remain hidden in the complex root canal system. The presence of bacteria that wasn’t completely removed during the initial treatment can be intricate and, in some patients, difficult to navigate. The inner layers of our teeth consist of porous tissues, including dentin and pulp. Since these areas contain blood vessels and nerves, any bacteria left behind can spread and cause a recurring infection.

• New Infection in Nearby Teeth

Sometimes, an infection in nearby teeth or gums can spread to the previously treated tooth, leading to recurring problems. This highlights the importance of oral hygiene and regular dental check-ups to catch any new problems before they worsen.

• Leaking or Loose Restorations

If the filling, crown, or other restoration placed after the root canal is loose or improperly sealed, bacteria can enter the tooth again. This is why ensuring your dental restoration is well-placed and secure is essential to preventing reinfection.

• Poor Oral Hygiene

Inadequate oral hygiene is another major factor contributing to reinfection. Once your root canal is completed, it’s crucial to maintain good dental habits to keep the area free of bacteria. Not brushing or flossing properly can allow bacteria to thrive in your mouth, increasing the risk of an infection. Plaque buildup and gum disease can also lead to complications after a root canal.

Signs of a Reinfected Root Canal

Identifying the signs of a reinfected root canal early can aid in avoiding further complications. If you’ve had a root canal and are experiencing any of the following symptoms, it’s time to consult your dentist nearby:

• Persistent Pain:If the tooth that received the root canal starts to hurt again, especially if the pain worsens over time, it could be a sign of reinfection. This discomfort may range from a dull ache to sharp, intense pain.
• Swelling and Sensitivity:Swelling around the treated tooth or sensitivity to hot or cold foods could also indicate reinfection. Any discomfort in the surrounding gums or facial area should be addressed immediately.
• Gum Drainage or Pus:This is a clear sign of infection if you notice pus or drainage around the tooth or gums. It could lead to more severe oral health issues if you don’t seek dental treatment promptly.
• Loose Restoration:A loose or dislodged crown or filling can expose the tooth to bacteria, leading to reinfection. If you notice that your restoration doesn’t feel secure, make an appointment with your dentist for an evaluation.
• Bad Taste or Odor:A persistent bad taste or odour in your mouth can be another warning sign of bacteria growth. If the infection isn’t treated quickly, it could spread to other areas, making treatment more complicated.

What to Do If You Have a Reinfected Root Canal

If you suspect your root canal has become reinfected, taking immediate action is important to prevent further damage. Several treatment options are available, depending on the severity of the reinfection:

• Root Canal Retreatment: Root canal retreatment involves removing the old filling material, thoroughly cleaning the space once more, and then resealing it to eliminate the infection. While this is an effective solution, it requires skilled care to remove the bacteria completely.
• Apicoectomy: This surgical procedure removes the root tip, allowing the dentist to clean the area and seal the root end to prevent further infection.
• Antibiotics:  Antibiotics can help control the infection and prevent it from spreading. But they may not cure the underlying problem, so they’re often used with other treatments like retreatment or surgery.
• Tooth Extraction: Tooth extraction may be the last resort if the infection is too severe and cannot be effectively treated with a retreatment or apicoectomy. While extracting a tooth is not ideal, it can be necessary to protect your overall oral health.

Preventive Measures to Avoid Future Root Canal Infections

Preventing reinfection starts with proper oral hygiene and regular dental care. Some tips to help you protect your teeth include; 

1. Brushing and flossing regularly 
2. Limiting sugary and acidic foods and drinks
3. Scheduling regular dental check-ups
4. Monitor your dental restoration
