Root Canal Treatment in Mississauga: What to Expect, Benefits, and Side Effects

Root canal treatment is one of the most misunderstood procedures in dentistry among patients. Due to long-standing myths, many patients feel anxious when they learn they need one. However, the reality is quite different: a root canal treatment does not cause pain—it eliminates it. It is a routine and highly predictable clinical procedure designed to save a severely damaged tooth that would otherwise require complete extraction.

At Appleday Dental Care, we believe that transparency builds trust. This comprehensive guide will explain in detail what the procedure involves, its benefits, and the typical side effects you can expect during recovery.

What is a root canal?

When the inner pulp of a tooth becomes infected or inflamed, the body cannot heal it on its own. If left untreated, the infection can form a painful abscess, destroy the surrounding jawbone, and ultimately require an emergency extraction.

What is the root canal treatment process like? Does it hurt?

During a standard root canal at our Mississauga clinic, our clinical team follows a precise, multi-step process:

Local Anesthesia: We completely numb the tooth and the surrounding area, ensuring you feel absolutely nothing during the procedure.
Infection removal: A small, precise opening is made in the crown of the tooth to access the damaged pulp chamber.
Cleaning and shaping: The infected tissue and nerves are carefully removed. The root canals are then thoroughly cleaned, disinfected, and shaped using advanced rotary instruments.
Hermetic Sealing: The empty canals are filled and sealed with a biocompatible material called gutta-percha to prevent future bacterial infiltration.
Structural Restoration: The tooth is sealed with a temporary or permanent filling. In most cases, a custom dental crown is strongly recommended to restore the tooth’s full chewing strength and prevent fractures.

Side Effects of Root Canal Treatment: What’s Normal and What Isn’t?

It’s completely normal to wonder how your body will feel after a dental procedure. Since root canal treatment addresses a deep internal infection, your body will go through a brief natural healing phase. Understanding the difference between expected side effects and warning signs is key to a smooth recovery.

Normal side effects of root canal treatments

Sensitivity when chewing

For the first 3 to 5 days, the treated tooth may feel sensitive or sore, especially when biting down. This is completely normal and occurs because the surrounding tissues and ligaments become inflamed due to the initial infection.

Jaw pain

Keeping your mouth open for an extended period during the procedure can cause mild muscle fatigue or stiffness in the jaw joint for 24 to 48 hours.

Mild gum irritation

The area where the anesthesia was administered or where the rubber dam was placed may be slightly tender or bruised for a day or two.

These temporary symptoms are easily managed with over-the-counter anti-inflammatory or pain medications recommended by our dentists.

Unusual side effects that warrant contacting us

Although root canal treatment has a success rate of over 95%, you should contact our clinic immediately if you experience any of the following symptoms:

Severe, throbbing pain that worsens over time and is not relieved by over-the-counter medications.
Visible swelling inside the mouth, on the gums, or on the cheek and face.
An uneven bite sensation (if the temporary filling feels too high, it puts additional pressure on the tooth and prolongs inflammation).
An allergic reaction to any post-procedure medication (such as a rash or itchy skin).

The Hidden Dangers of Home Remedies for Root Canal Treatment

When faced with sudden tooth pain, it can be tempting to look for quick fixes online. However, searching for ways to “naturally remove a tooth nerve” or using aggressive home remedies, such as crushing aspirin directly onto the gums, is extremely dangerous.

Teeth cannot regenerate or fight deep internal infections without professional intervention. Attempting to treat or ignore an infected root at home can lead to serious systemic infections, chemical burns on the gums, and quickly turn a simple clinical procedure into a serious medical emergency. The only safe way to eliminate bacteria is through a sterile, professional root canal.
