Of all the treatments in dentistry, root canal therapy has perhaps the most unfair reputation. Ask most people what they imagine it involves and the answers cluster around words like painful, invasive, and frightening. The reality, for most patients who undergo the procedure with modern techniques and adequate anaesthesia, is rather different.
Why Root Canal Treatment Is Needed
Root canal therapy becomes necessary when the pulp — the soft tissue inside the root canals of a tooth — becomes infected or inflamed. This can occur as the result of deep decay, a cracked or fractured tooth, repeated dental procedures on the same tooth, or trauma. Left untreated, an infected pulp can lead to significant pain, abscess formation, and ultimately tooth loss. Root canal treatment removes the infected tissue, cleans and shapes the canals, and seals them to prevent reinfection — preserving the tooth in a way that no other treatment can replicate.
Modern Treatment: What to Actually Expect
A well-administered root canal procedure should be no more uncomfortable than having a filling placed. Modern local anaesthesia is highly effective, and the tooth is completely numb before any treatment begins. The procedure itself typically takes between one and two hours, depending on the complexity of the root canal anatomy. Most patients are surprised — often relieved — by how manageable the experience is. Post-operative discomfort is usually mild and responds well to over-the-counter pain relief.
“The most common thing I hear after a root canal is: I wish I hadn't waited so long to have it done.”
