No one enjoys tooth pain — and while not every ache is serious, some symptoms may be a sign that you need more than just a filling. One common treatment for deep tooth infections is root canal therapy. Although it may sound intimidating, a root canal can actually relieve pain and help save your natural tooth.
So, how do you know if you might need one? Here are some key signs to watch for.
1. Persistent Tooth Pain
If you’re experiencing continuous pain — whether it’s sharp, dull, or throbbing — especially when chewing or applying pressure, this could indicate an infection in the tooth pulp. Pain that lingers even after the trigger is gone should never be ignored.
2. Sensitivity to Hot or Cold
A little sensitivity is normal. But if you feel sharp pain or prolonged discomfort after drinking hot coffee or eating ice cream, it could mean the nerve inside your tooth is damaged or inflamed.
3. Swollen or Tender Gums
Swelling near the affected tooth may be a sign that infection has spread to the surrounding tissues. You might also notice a small bump on the gum that resembles a pimple — this is called a dental abscess and often requires immediate care.
4. Tooth Discolouration
A tooth that suddenly appears darkened or greyish may indicate trauma or damage to the nerve. This is especially common after a fall or injury and may be one of the early signs that the tooth is dying.
5. Pain When Biting or Touching
If your tooth feels extra sensitive or painful when touched, it could be inflamed from infection. This kind of touch sensitivity is often a signal that the pulp is compromised.
6. Cracked or Chipped Tooth
A deep crack or chip — whether from a sports injury, grinding, or biting something hard — can expose the inner layers of your tooth to bacteria. If left untreated, this can lead to infection that requires root canal therapy.
7. Lingering Bad Taste or Smell
A foul taste or odour in your mouth, even after brushing and flossing, can sometimes indicate an underlying infection in the tooth or gum tissue.
When to See Your Dentist
If you’re experiencing any of these symptoms, don’t wait it out. The earlier you catch an issue, the more likely you’ll be able to avoid complications. A simple dental exam — often with an X-ray — can confirm whether a root canal is needed.
Most importantly, modern root canal therapy is safe, effective, and far less uncomfortable than you might think. It’s a smart way to relieve pain and preserve your natural smile.
