Root canal therapy in St. Catharines
Persistent tooth pain or sensitivity can be a sign of infection deep inside the tooth. At Hartzel Dental, we perform gentle root canal therapy in St. Catharines, ON to remove infection, ease discomfort, and preserve your natural tooth whenever possible. Our focus is on comfort, precision, and long-term protection.

Why root canal treatment matters
When decay or trauma reaches the inner nerve of a tooth, it can cause significant pain and swelling. Left untreated, the infection can spread or lead to tooth loss. Root canal treatment cleans and seals the tooth’s inner chamber to stop further damage in its tracks. Preserving your natural tooth also means avoiding the need for extractions or implants down the road.
What to expect during your visit
Treatment begins with digital imaging to accurately pinpoint the infection. Your dentist will gently remove the damaged tissue, disinfect the root canals, and seal them with a durable material. In many cases, a crown is placed afterward to strengthen and protect the tooth. For patients dealing with urgent pain, we offer same-day care so you’re not left waiting when it matters most.


Comfortable, reassuring care from start to finish
Root canal therapy is much more comfortable than its reputation suggests. Local anesthesia keeps you at ease throughout the procedure, and our team takes time to explain every step so there are no surprises. Most patients return to normal activities the following day, with any residual discomfort resolving quickly as the tooth heals.
When to seek care for a fractured or infected tooth
A fractured tooth, persistent ache, or swelling near the gumline are all signs that prompt care is needed. Our dentists will evaluate your condition thoroughly and walk you through the best treatment options for your situation. Catching an infection early gives us the best chance of saving the tooth and preventing more complex problems later.

Frequently asked questions
Does a root canal hurt?
Most patients are surprised by how comfortable the procedure is. The area is fully numbed before we begin, and many people find the relief from pre-treatment pain far outweighs any mild soreness afterward.
How long does treatment take?
Most root canals are completed in one to two appointments, each lasting about 60 to 90 minutes depending on the complexity of the tooth.
Do I need a crown after a root canal?
In most cases, yes. A crown protects the treated tooth from fracture and restores its full function. Your dentist will confirm whether one is needed based on your specific situation.
Is it better to just pull the tooth instead?
Whenever possible, saving your natural tooth is the healthier choice. It helps preserve your bite alignment, prevents neighbouring teeth from shifting, and avoids the need for a bridge or implant.
