Do I really need a root canal?

What a root canal actually treats

Inside every tooth is a soft core of nerve and blood vessels called the pulp. When decay, a crack or trauma lets bacteria reach it, the pulp becomes inflamed and then dies. That is not something a filling can fix — the infection is inside the tooth, and it will spread into the bone at the root tip if it is left.

Root canal treatment removes the infected pulp, disinfects the space, and seals it. The tooth stays in your mouth. The alternative, when the pulp is genuinely dead, is extraction.

Signs that usually do justify it

• Pain that lingers after hot or cold — several seconds or minutes, not a quick zing
• Pain that wakes you at night, or that throbs on its own without being triggered
• Pain on biting or tapping that particular tooth
• A tooth that has darkened compared to its neighbours
• A gum boil or abscess near the root, sometimes with a bad taste
• A dark area at the root tip on an x-ray — this is infection in the bone, and it is visible evidence you can ask to be shown

Notably, a tooth can also need root canal treatment while causing no pain at all — a nerve can die quietly. That is a legitimate reason for a recommendation that feels like it came from nowhere, and a fair thing to ask to see evidence for.

Signs that often do not

• A brief zing to cold that stops as soon as the cold does — usually ordinary sensitivity, often from exposed root surfaces or a worn spot
• Generalised sensitivity across several teeth — rarely a nerve problem in one tooth
• Discomfort in a newly placed filling — often settles over a few weeks
• Pain that is actually from your gums, or from clenching and grinding

Five questions worth asking

1. "Can you show me on the x-ray?" A reasonable dentist will happily point at the problem.
2. "What test led to this?" Cold testing, electric pulp testing and tapping all give real information about whether a nerve is alive.
3. "What happens if I wait?" Sometimes the honest answer is "it gets worse and more expensive." Sometimes it is "we can watch it."
4. "Is there a more conservative option?" For a nerve that is inflamed but not dead, there sometimes is.
5. "Will it need a crown afterwards, and is that in the quote?" Back teeth often do, and it materially changes the total.

What it costs here, and how long it takes

The price varies with the tooth. Front teeth usually have one canal; back molars can have three or four, and each has to be cleaned and sealed individually — so a molar is more work than an incisor. You will be quoted for your specific tooth before anything starts.

One visit, not several

Most practices split root canal treatment across two or more appointments, with a temporary dressing in between. We complete it in a single visit. Dr. Jagdeo is certified in rotary endodontics — a technique that shapes the canals with a powered instrument rather than by hand, which is both faster and more consistent than the traditional method.

That matters for more than convenience. Every extra appointment is another injection, another period with a temporary filling that can leak or fracture, and another day of not knowing whether it worked. If you are anxious about the appointment itself, sedation is available.

When to get a second opinion

Get one if you were not shown evidence, if the tooth does not hurt and you are unclear why treatment is needed, if the total cost is significant, or simply if you are not comfortable. Delaying a genuinely necessary root canal is not free — infection spreads and teeth become unsaveable — so the goal is a quick, confident decision rather than months of avoidance.
