Dentist treating patient with rotary endodontic tools Root Canal Mississauga.

If you’re dealing with persistent tooth pain or sensitivity, a root canal may be the solution to save your natural tooth and eliminate discomfort. At Trio Dentistry in Mississauga, we provide gentle, effective root canal therapy using advanced technology to ensure a smooth and efficient experience.

Our general dentist is trained in performing root canals using digital X-rays, apex locators, and rotary endodontic instruments to increase accuracy, reduce discomfort, and promote faster healing. Whether you’re experiencing pain from deep decay, trauma, or infection, we’re here to restore your oral health with confidence.

What Is a Root Canal?

A root canal (also known as endodontic treatment) is a dental procedure that treats infection or inflammation in the pulp (inner tissue) of a tooth. The procedure removes the infected tissue, cleans the root canals, and seals the space to prevent reinfection.

This treatment allows you to:

  • Keep your natural tooth
  • Eliminate pain and sensitivity
  • Prevent the need for extraction
  • Maintain chewing ability and alignment


Root canal therapy is often misunderstood, but at Trio Dentistry, we make it a stress-free, comfortable experience for patients across Mississauga.

When Do You Need a Root Canal?

A root canal may be necessary if:

  • You have deep decay reaching the pulp
  • There’s an infection or abscess near the tooth root
  • You’ve experienced trauma such as a cracked or broken tooth
  • The tooth has undergone repeated dental procedures

Symptoms can include:

  • Persistent toothache or pressure
  • Sensitivity to hot or cold
  • Swollen or tender gums
  • A pimple-like bump on the gums


If you experience any of these signs, contact us for a root canal evaluation in Mississauga.

Advanced Technology We Use

We’re committed to precision and comfort. That’s why we use:

Digital X-rays
Offer detailed imaging with minimal radiation exposure, allowing us to locate infection and shape the treatment plan accurately.

Apex Locators
Help determine the exact length of the root canal to ensure thorough cleaning and prevent over-instrumentation.

Rotary Endodontics
Electric-powered instruments that clean and shape canals more efficiently and comfortably than traditional hand files.

These technologies reduce treatment time and improve outcomes, giving our Mississauga patients the best care available.

The Root Canal Process

1. Diagnosis and Imaging
We begin with a thorough exam and digital X-rays to confirm the need for a root canal.

2. Anesthesia
Local anesthesia is administered to ensure complete comfort throughout the procedure.

3. Pulp Removal and Cleaning
We remove the infected or damaged pulp, disinfect the canals, and shape them using rotary instruments.

4. Sealing the Tooth
The cleaned canals are filled and sealed to prevent future infection. A temporary or permanent filling is placed.

5. Final Restoration
In most cases, a dental crown is recommended to protect the tooth. We’ll schedule a follow-up to place the crown.

How Much Does a Root Canal Cost in Mississauga?

Root canal pricing depends on the complexity and location of the tooth:

  • Front teeth (incisors/canines): typically $800–$1,200
  • Molars or complex cases: may cost over $1,200

Insurance plans often cover a significant portion of endodontic treatment. At Trio Dentistry, we offer:

  • Direct insurance billing
  • Transparent estimates before starting treatment
  • Flexible payment options for uninsured patients

Will It Hurt?

Thanks to modern techniques and anesthesia, most patients report little to no discomfort during or after a root canal. In fact, the procedure relieves the pain caused by infection or inflammation.

Some mild soreness is normal for 1–2 days after treatment, but this can be managed with over-the-counter medication.

What Happens If You Delay a Root Canal?

Delaying treatment can allow infection to spread, potentially leading to:

  • Bone loss around the root
  • Severe pain or abscess
  • Tooth loss
  • More expensive or invasive procedures later on


Prompt treatment is the key to saving your tooth and avoiding complications.

Frequently Asked Questions

How long does a root canal take?

Most root canals are completed in 60–90 minutes. Complex cases may need a second visit.

Will I need a crown afterward?

Yes, especially for molars or large restorations. A crown strengthens the tooth and prevents future breakage.

Is it better to extract the tooth?

We recommend saving the tooth whenever possible. Extractions can lead to shifting and require additional restorations.

Can I go to work after a root canal?

Yes. Most patients return to normal activities the same or next day.

Are root canals covered by insurance?

Most dental plans include coverage. We’ll confirm benefits before treatment.
