Understanding the Symptoms of Root Canal Infection: A Comprehensive Guide


Each year, countless Australians turn to their local dental clinics, seeking relief from dental pains and aches. One culprit often identified is the dreaded root canal infection. To effectively combat this issue, understanding its symptoms and causes is crucial. Here’s your guide to delving deeper into the mystery of root canal infections.

Anatomy of a Tooth

Before we plunge into the realm of root canal infections, it’s helpful to understand the structure of our teeth. At a glance, our teeth may seem simple, but they’re intricate structures with different parts.

  • Crown: The visible part of the tooth when you smile or open your mouth.
  • Root: Secured beneath the gum line, this anchors the tooth into the jawbone.
  • Pulp: Located in the tooth’s centre, it contains the vital nerves and blood vessels.

The pulp plays a pivotal role in the tooth’s health, providing it with essential nutrients and also signaling pain, which can indicate issues like infections.

What is a root canal infection?

Simply put, it occurs when bacteria invade the pulp chamber, leading to inflammation and infection. But how does this happen? Often, the causes include:

  • Deep dental cavities that reach the pulp.
  • Traumatic injuries that damage the tooth
  • Cracks or chips in the tooth, creating access points for bacteria.
  • Failed or old dental fillings that no longer seal the tooth effectively.

Common Symptoms of Root Canal Infection

Knowing the symptoms can mean the difference between timely treatment and potential tooth loss. Here’s what to look out for:

  • Pain: This isn’t your run-of-the-mill toothache.
    • Sharp, intense pain when biting down—think of it as a jolt.
    • A persistent, throbbing pain that doesn’t let up.
    • A deep sensitivity to hot and cold beverages, lasting longer than usual.
  • Swelling:
    • Around the troubled tooth, the gum might feel puffy or look reddened.
    • In more severe cases, swelling can extend to the face or neck.
  • Pus discharge: Not only can this create a foul taste, but you might also detect an unpleasant odour, signalling an infection.
  • Discoloration of the tooth: Sometimes, an infected tooth can appear darker. This discoloration stems from changes within the infected pulp.
  • Gum issues:
    • The gums might become tender to touch or appear swollen.
    • Keep an eye out for pimple-like formations on the gums. These are dental abscesses, filled with pus from the infection.

Complications if Left Untreated

Ignoring a root canal infection isn’t just about bearing the pain. If left unchecked, the consequences can be dire.

  • The infection can spread, risking neighbouring teeth and potentially the jawbone.
  • Abscesses might form, which are painful and can lead to more severe systemic infections.
  • The affected tooth might decay to a point where saving it is impossible.
  • In rare cases, untreated dental infections can lead to sepsis, a life-threatening condition.

According to the Australian Dental Association (ADA), timely treatment of dental infections is paramount to preventing more significant health issues.

Diagnosis of Root Canal Infection

If you suspect you’re grappling with the infection, your dentist will typically:

  • Conduct a thorough clinical examination, checking for signs of swelling, tenderness, and other symptoms.
  • Take dental X-rays. These offer a clearer view of what’s happening beneath the surface, revealing any abscesses or infections.
  • In some cases, other diagnostic tests might be required to ascertain the infection’s extent and how best to treat it.

In Australia, it’s essential to have regular dental checkups. Not only does this comply with the ADA’s recommendations, but it also ensures early detection of potential issues, making treatment more effective and less invasive.

Treatment Options

Facing a root canal infection? Fear not. Modern dentistry offers various treatments tailored to the severity and specifics of the infection. Here’s a glimpse into what you might expect:

  • Root Canal Treatment (RCT):
    • This procedure is designed to save the natural tooth by removing the infected pulp. Once cleaned and disinfected, the tooth’s inner chamber is filled, and often the tooth is crowned for additional protection.
    • While many may shudder at the mention of a ‘root canal‘, advancements in dental technology and anaesthesia mean that the procedure is usually no more uncomfortable than a typical filling.
  • Tooth Extraction:
    • Sometimes, the tooth may be too damaged or the infection too advanced for RCT. In such instances, extraction might be the best option.
    • However, extracting a tooth isn’t the end; often, dental professionals recommend replacing it with an implant or bridge to preserve the jaw’s structure and functionality.
  • Antibiotics:
    • If the infection has spread or there’s a risk of it doing so, your dentist might prescribe antibiotics.
    • It’s crucial to understand that antibiotics alone won’t solve the problem; they manage the infection, but the underlying cause still requires treatment.

Prevention: Keeping Your Teeth Healthy

An ounce of prevention is worth a pound of cure, and this is undoubtedly true for dental health.

  • Regular Dental Check-ups: The Australian Dental Association recommends regular check-ups to detect and manage potential issues early on.
  • Proper oral hygiene practices such as brushing twice a day, flossing daily, and using mouthwash can significantly reduce the risk of infections.
  • Avoiding Trauma to the Teeth: While accidents happen, wearing mouthguards during contact sports and avoiding using teeth as tools can prevent unnecessary damage.
  • Dietary Choices: A balanced diet low in sugars and acids is pivotal. Such foods can erode enamel and pave the way for bacteria.

While these infections common, are not to be taken lightly. By recognising the symptoms early and seeking professional care, you stand a good chance of saving your tooth and staving off more severe health implications. Regular dental checkups and maintaining good oral hygiene can be your armour against such infections. And remember, when it comes to dental concerns, early intervention is always best.

Most patients can return to their regular activities the next day, but it’s essential to follow the dentist’s aftercare advice to ensure a smooth recovery.

3. Can root canal infections return?

While rare, a tooth that has undergone RCT can get re-infected if it isn’t adequately sealed or if the infection wasn’t entirely removed during the initial treatment.

4. Are there alternatives to root canal treatments?

Depending on the tooth’s condition and the infection’s severity, alternatives like tooth extraction followed by a dental implant or bridge might be considered.

Root canal infections are a dental concern that shouldn’t be overlooked. Yet, with the right knowledge, professional advice, and timely intervention, they can be managed effectively.
