If you’re experiencing persistent tooth pain, you’re right to be concerned, but the good news is that modern root canal treatment is far more comfortable than you might think. But how do you know if you need a root canal treatment in Markham?
Most people know they need a root canal when they experience persistent pain, prolonged sensitivity to hot or cold, or swelling around a tooth.
We understand that “root canal” can sound scary. This guide helps you recognize symptoms, know when to seek care, and understand what to expect.
Below, you’ll find a clear symptom checklist, honest answers about pain and costs, and guidance on when treatment can wait versus when it’s urgent.
What are the 7 warning signs you may need a root canal?
These root canal symptoms are recognized as key indicators of pulp infection requiring treatment. If you’re experiencing several of these signs together, it’s time for a professional evaluation.
1. Persistent tooth pain that won’t go away
Constant, throbbing pain, or pain that comes and goes but keeps returning, is the most common sign. The pain may be deep in the tooth, radiating to your jaw, ear, or other teeth.
2. Prolonged sensitivity to hot and cold
If your tooth hurts when you drink coffee or ice water AND the pain lingers for 30+ seconds after removing the temperature source, this suggests nerve damage or infection inside the tooth.
3. Swollen, tender, or discoloured gums near the tooth
Puffy gums, tender to the touch, darker than normal, or with a small pimple-like bump may indicate infection.
4. Pain when chewing or applying pressure
If biting down causes sharp pain or if the tooth feels different when you chew on that side, the pulp inside may be infected or inflamed.
5. Tooth discoloration (gray or dark brown)
A tooth that has darkened or turned grayish, especially after trauma or without other obvious cause, may indicate the pulp is dying or dead.
6. A pimple or bump on your gums
Called a dental abscess or fistula, this pus-filled bump may drain, release an unpleasant taste, and indicate active infection that requires treatment.
7. Loose tooth or tooth that feels different
A tooth that feels slightly loose or different from others may indicate that an infection has weakened the supporting bone.
Important: Sometimes you won’t experience any symptoms at all, especially in the early stages of infection. This is why regular dental exams are essential; our digital X-rays can detect infections before pain develops, allowing earlier, simpler treatment.
If you’re experiencing 2 or more of these symptoms, schedule a consultation. Early diagnosis means simpler, less invasive treatment.
What is a root canal, and why would you need one?
What is a root canal?
Root canal therapy is a procedure that removes infected or inflamed pulp (the soft tissue inside your tooth containing nerves and blood vessels) from the root canals of your tooth.
Your dentist in Markham cleans the canals, disinfects the space, and seals it to prevent future infection.
Why would you need one?
You need a root canal when bacteria reach the pulp inside your tooth, usually through deep cavities that penetrate through enamel and dentin to the pulp, cracked or chipped teeth that expose the pulp to bacteria, repeated dental procedures on the same tooth that weaken it, or trauma from accidents or sports injuries.
Research published in NCBI confirms that specific bacterial pathogens are strongly associated with endodontic signs and symptoms, making professional diagnosis and treatment essential.
What happens if you don’t treat an infected tooth?
Without treatment, the infection spreads into the bone surrounding your tooth, causing bone loss that weakens the tooth’s foundation, abscess formation that can spread to other parts of your body, and eventual tooth loss requiring more expensive replacement. In rare cases, serious infections affect overall health.
Root canal treatment is recommended by major medical institutions as the standard of care for preserving natural teeth when pulp becomes infected.
We use digital X-rays and diagnostic testing to confirm whether root canal treatment is truly necessary, we never recommend procedures you don’t need.
Do root canals hurt?
Let’s address the question everyone Googles at 2 AM: “Are root canals painful?” The short answer: Modern root canal treatment is no more uncomfortable than getting a cavity filled.
Why root canals have a bad reputation
Decades ago, before modern anesthesia and techniques, root canals were uncomfortable. But today’s procedures are completely different.
The pain associated with root canals comes from the INFECTION, not the treatment; the procedure actually RELIEVES pain.
What makes modern root canals comfortable
Today’s root canal treatment involves effective local anesthesia that completely numbs the area (you’ll feel pressure but not pain), sedation options available for anxious patients (oral sedation or nitrous oxide), modern rotary instruments that complete procedures 30 to 40% faster than manual techniques, and improved anesthesia delivery using systems like the Dental Vibe that eliminate injection pain.
Studies show that modern endodontic techniques significantly reduce patient discomfort during and after treatment.
What you’ll actually feel
During treatment: Numbness and pressure, but no pain. After treatment: Mild soreness for 2 to 3 days, manageable with over-the-counter pain relievers. Most patients return to normal activities the same day.

How do dentists diagnose if you need a root canal?
At Forestbrook Dental, we never recommend root canal treatment without a thorough diagnosis. Here’s exactly what we do to confirm whether you need treatment and rule out simpler alternatives first.
The diagnostic process:
Step 1: Symptom discussion and medical history
We’ll ask detailed questions about your pain (when it started, what triggers it, how long it lasts) and review your dental history.
Step 2: Visual examination
We examine the tooth for visible cracks, decay, or damage, and check your gums for swelling, discoloration, or abscesses.
Step 3: Diagnostic tests
- X-rays/Digital radiography: Reveals infection in the root, bone loss around the tooth, or abscess formation that is not visible
- Temperature sensitivity test: Applying cold to determine if the nerve is still responsive or if it has died
- Percussion test: Gently tapping the tooth to identify if inflammation has spread to the surrounding tissues
- Bite pressure test: Checking if biting down causes pain, indicating pulp inflammation
- Vitality testing: Using electrical stimulus to test if the tooth’s nerve is alive or dead
Ruling out other causes first
Before confirming the need for a root canal, we rule out simple cavities that can be treated with fillings, sinus infections that can cause tooth pain without dental problems.
TMJ issues that can refer pain to teeth, and cracked fillings that cause sensitivity without a pulp infection.
We only recommend root canals when diagnostic tests confirm pulp infection or irreversible nerve damage.
If there’s any uncertainty, we may refer you to an endodontist (root canal specialist) for a second opinion. We want you to feel completely confident in your diagnosis.
Can you wait if you need a root canal?
We understand that cost, schedule, or anxiety might make you consider delaying treatment. Here’s honest guidance on when you can wait safely versus when treatment is urgent.
Emergency situations (treat within days):
- Severe, constant throbbing pain that prevents sleep or eating
- Visible swelling in the face, jaw, or neck
- Fever accompanying tooth pain
- Pus drainage from gums or foul taste in the mouth
- Breathing or swallowing difficulty
These symptoms indicate a spreading infection requiring immediate care — call us for an emergency appointment.
Moderate urgency (treat within 1-2 weeks):
- Persistent pain that’s manageable with over-the-counter pain relievers
- Intermittent pain when chewing or temperature sensitivity
- Small gum boil without severe swelling
- Tooth discoloration without pain
Schedule consultation within 2 weeks, infection is present but not immediately dangerous.
Can be monitored (appointment within 3-4 weeks):
- No symptoms, but the dentist saw an infection on the X-ray
- Mild occasional sensitivity only
- Previous root canal trauma, but currently no pain
These situations need treatment but aren’t emergencies — you have time to research options and arrange financing.
What happens if you delay too long:
- 2-4 weeks delay: Pain worsens, infection spreads to the surrounding bone
- 1-3 months delay: Abscess formation, possible tooth loss, bone damage
- 6+ months delay: Tooth likely not savable, extraction + implant needed (much more expensive)
Bridge solution if you need time: If you need 4 to 6 weeks to arrange financing, antibiotics can temporarily control infection while you prepare. This is NOT a long-term solution, but it can buy you time to plan.
During your free consultation, we’ll assess your specific urgency level and help you understand if treatment can wait or if action is needed now.

Frequently Asked Questions
Can you have a root canal without symptoms?
Yes, sometimes infections develop without pain, especially in early stages. This is why regular dental checkups with X-rays are essential — they help you know if you need a root canal before symptoms appear.
How urgent is a root canal?
Depends on symptoms. Severe swelling, fever, or constant pain requires treatment within days. Moderate intermittent pain should be addressed within 1-2 weeks. Symptomless cases found on X-ray can be scheduled within 3-4 weeks.
What’s the success rate of root canal treatment?
90-95% long-term success with proper care. About 5-10% may need re-treatment, but this is still more cost-effective than extraction and replacement.
Is a root canal more expensive than an extraction?
Initially cheaper to extract ($300-500), but replacement with an implant costs $3,000-5,000. Root canal + crown ($1,800-3,000) saves you money in the long term while preserving your natural tooth.
How do dentists confirm you need a root canal?
Through X-rays showing infection, nerve conduction tests, temperature sensitivity tests, percussion tests, and ruling out simpler causes like cavities or sinus issues.
Should I get a second opinion on the root canal diagnosis?
Yes, especially for symptomless cases found only on X-ray. We encourage second opinions and welcome patients seeking confirmation of diagnoses from other practices.
