Why You Might Need a Root Canal — And Why It’s Worth It

For many people, the words “root canal” can trigger anxiety — but this long-misunderstood procedure is actually one of the most effective ways to save a natural tooth and avoid more serious dental problems. In fact, root canal therapy is a routine, highly successful treatment designed to relieve pain, stop infection, and restore your oral health.

If you’ve been told you might need a root canal, or you’re experiencing persistent tooth pain, this article explains what’s involved — and how Dr Amish Bhayani at Inspired Dental Care in Exeter can help.

What Is a Root Canal?
The term “root canal” refers both to the part of the tooth and the treatment itself.

Inside each tooth is a soft tissue called the pulp, which contains nerves, blood vessels, and connective tissue. This extends down through narrow canals within the roots of the tooth. If the pulp becomes infected or inflamed, it can cause significant discomfort — and if left untreated, the infection can spread to the surrounding bone and tissues.

Root canal treatment removes the infected or damaged pulp, disinfects the inside of the tooth, and seals it to prevent further issues. The aim is to save the tooth so it can continue to function normally — without needing to be removed.

Why Might I Need a Root Canal?
Root canal therapy is needed when the dental pulp becomes damaged beyond repair. This can happen for a number of reasons, including:

• Deep tooth decay that reaches the inner layers of the tooth
• Repeated dental procedures on the same tooth
• Faulty crowns or restorations that allow bacteria to enter
• Cracks or chips that expose the pulp
• Injury or trauma to the tooth — even if there’s no visible damage

If the infected pulp isn’t removed, the condition can worsen. This may lead to an abscess, bone loss around the tooth, and eventually, tooth loss.

Signs You May Need Root Canal Treatment
Not all teeth that need root canal therapy are painful — which is why regular check-ups are so important. However, some warning signs to watch out for include:

• Persistent toothache, especially when chewing or applying pressure
• Sensitivity to hot or cold that lingers
• Swelling or tenderness around the tooth or nearby gums
• A darkened or discoloured tooth
• A recurring pimple or boil on the gum

These symptoms may come and go, but the underlying issue won’t resolve on its own.

What Happens During Root Canal Treatment?
Root canal therapy is typically completed in one or two visits. Here’s what to expect:

• Assessment and imaging – Your dentist will examine the tooth and take radiographs to assess the extent of the damage.
• Anaesthetic – Local anaesthetic is used to fully numb the area, ensuring the treatment is pain-free.
• Access and cleaning – A small opening is made in the tooth. The infected pulp is removed, and the root canals are cleaned, shaped, and disinfected.
• Sealing – The canals are filled with a biocompatible material (usually gutta-percha) and sealed to prevent reinfection.
• Restoration – Most root-treated teeth will require a crown to restore their strength and function. Your dentist will recommend the most suitable option.

Most patients experience immediate relief from pain following treatment. A smooth recovery is common, with over-the-counter pain relief and good oral hygiene usually all that’s needed while the tooth settles.

Can’t I Just Have the Tooth Removed?
While extraction may seem like a simpler solution, keeping your natural teeth is generally better for your long-term dental health. Here’s why:

• Natural teeth help maintain jawbone strength — Removing a tooth can eventually lead to bone loss.
• Tooth loss can affect your bite — Adjacent teeth may shift, leading to changes in bite alignment and further problems.
• Replacing a missing tooth takes time and costs more — Dental implants and bridges are effective but require more appointments and higher investment.
• A root-treated tooth functions and feels natural — You can chew, speak, and smile with confidence.

Where possible, saving your tooth through root canal treatment is usually the most conservative and beneficial option.
