When most people hear the words “root canal,” they panic. A root canal is a tooth-saving treatment designed to relieve pain, not cause it. It becomes necessary when the nerve inside your tooth becomes infected or inflamed which can cause you pain. It is the last treatment designed to keep your tooth, if you ignore the symptoms it can lead to worsening infection, tooth loss, and even more complicated (and expensive) treatments down the line.
If you’ve been wondering whether that nagging toothache is something more serious, here are five common tooth pain symptoms that signal you may need a root canal:
1.Persistent Tooth Pain
Occasional sensitivity or momentary discomfort isn’t unusual but constant, throbbing, or recurring pain is a red flag. Root canal related pain may come and go, but it tends to return in waves, often worsening when you chew, apply pressure, or lie down. This type of pain suggests the nerve inside the tooth may be damaged or infected.
2. Sensitivity to Hot or Cold That Lingers
It’s normal to feel a quick zing when you sip hot coffee or bite into ice cream. What’s not normal is sensitivity that lingers.
If the ache lasts more than a few seconds—or feels sharp, deep, or stabbing—your tooth could be compromised.
3. Swollen or Tender Gums
Gum swelling near one specific tooth often indicates infection. You might see:
- A small bump or pimple-like lesion (an abscess)
- Redness or inflammation
- Soreness when you touch the gum
This swelling is your body’s way of signalling that something deeper beneath the gumline needs attention.
4. Darkened or Discoloured Tooth
A tooth that turns grey, brown, or black compared to its neighbour’s may be suffering from internal damage. Trauma, decay, or infection can cut off blood flow to the nerve, causing the tooth to darken, often requiring a root canal to prevent further complications.
5. Pain When Chewing or Touching the Tooth
If biting down feels sharp, uncomfortable, or strangely sensitive, it may be due to nerve inflammation or infection inside the tooth. This symptom often becomes more noticeable over time and commonly accompanies one or more of the signs above.
