Why Do I Need a Root Canal?
If you’ve ever wondered why do I need a root canal, you’re not alone. Many people feel anxious when their dentist suggests this treatment, but a root canal is often the best way to save a damaged or infected tooth. Instead of removing the tooth, this procedure restores it to normal function—relieving pain and protecting your smile for years to come.
What Are the Signs You Need a Root Canal?
The most common signs that you may need a root canal include:
-
Persistent toothache or throbbing pain
-
Sensitivity to hot or cold that lingers after exposure
-
Swelling or tenderness around the gums
-
A dark or discoloured tooth
-
A small pimple-like bump (abscess) on the gums
-
Pain when chewing or touching the tooth
These symptoms usually mean the tooth pulp (the soft tissue inside) is infected or damaged. A root canal removes the infection and saves the tooth from extraction.
What Is the Main Cause of Needing a Root Canal?
The main cause is bacterial infection within the tooth pulp. This infection can result from:
-
Deep decay: When cavities reach the inner part of the tooth
-
Repeated dental procedures: Over time, this can weaken or expose the pulp
-
Cracked or chipped teeth: Allow bacteria to enter
-
Injury or trauma: Even if there’s no visible crack, the pulp may be damaged
Once the pulp becomes infected, it cannot heal on its own. Without treatment, the infection can spread to surrounding bone, leading to severe pain or even tooth loss.
Is a Root Canal Really Necessary?
Yes—if your tooth is infected or badly decayed, a root canal is necessary to stop the infection and save your natural tooth. Without it, the tooth may eventually die, and extraction might be the only option.
Root canal treatment helps you avoid:
-
Ongoing pain and swelling
-
Abscess formation
-
Tooth loss
-
Costly replacement treatments like implants or bridges
It’s a reliable, long-term solution that preserves your natural bite and smile.
Why Do Dentists Push for Root Canals?
Dentists recommend root canals not to “push” unnecessary treatments, but to save your natural tooth—which is always the best outcome.
A tooth that has undergone a successful root canal can last a lifetime with proper care. Removing the tooth might seem easier, but it can lead to:
-
Shifting of neighbouring teeth
-
Bite misalignment
-
Jawbone loss over time
So, your dentist suggests a root canal because it’s the healthiest and most conservative way to treat the problem.
Is It Better to Get a Root Canal or Extraction?
In most cases, a root canal is better than extraction. Here’s why:
-
You keep your natural tooth
-
It maintains your chewing efficiency
-
It prevents bone loss
-
It looks and feels natural
Extraction is only recommended when the tooth is too damaged to repair. Even then, it often requires additional treatments like dental implants, which are more costly and time-consuming.
What Happens If You Avoid a Root Canal?
Ignoring the need for treatment can lead to severe infection, abscess formation, swelling, and even systemic issues if bacteria enter the bloodstream. Eventually, the pain becomes unbearable, and tooth removal becomes unavoidable.
In Summary
Root canal treatment is not something to fear—it’s a safe, effective way to relieve pain and save your tooth. If you have persistent pain, swelling, or sensitivity, don’t delay. Early diagnosis can make the procedure quicker and more comfortable.
