Root Canal Therapy for Templeton-Sinclair Residents

Some people cope with treatment by knowing the order of events. If that sounds like you, this page walks through a root canal from the first numbing to the final restoration.

The procedure in sequence

Five Stages, Start to Finish

Under the hard outer layers of enamel and dentin lies the pulp, a soft core of nerves, blood vessels and connective tissue. Its branches run down narrow channels within the roots. Treatment becomes a consideration when deep decay, a crack or an injury leaves this tissue unable to recover.

The work follows a logical order: numb and isolate, open, clean and shape, seal, then restore. Templeton-Sinclair is an area in Winnipeg, and residents having this treatment attend our clinic on McPhillips Street. Exactly how the stages divide across appointments is something the dentist explains once your tooth has been examined.

A clear order of events

Every stage has a purpose, and each one sets up the stage that comes after it.

Ask at any point

You are welcome to hear what is happening now and what is coming up next.

The final stage counts

Sealing the canals does not end the job, because the tooth still has to be rebuilt.

Inside the tooth, then on top of it

Two jobs make up one treatment.

It helps to think of the process as dealing first with the space within the tooth, and then with the structure surrounding it.

The inner work

The first job is to remove affected pulp tissue and leave the channels clean enough to be closed off.

  • Instruments reach the channels through a small opening made in the tooth.
  • Careful shaping prepares the narrow spaces that run through the roots.
  • Disinfection follows, so that the area is ready to be closed.
  • Filling the cleaned system lowers the chance of reinfection.

The outer rebuild

The second job gives the tooth back its strength for chewing, since damage has already cost it some structure.

  • A filling closes the access opening and rebuilds lost areas.
  • Back teeth commonly need a crown or similar protective coverage.
  • Advice for front teeth varies with your bite and what structure remains.
  • Putting this stage off can leave the treated tooth at risk.

Teeth differ, so some stages may vary for yours. Anatomy, infection and the restoration planned all influence the details.

Stage by stage

What happens, in the order it happens.

This is the general sequence after an examination and X-rays confirm the diagnosis. Some teeth can be treated in one appointment and others take more.

Request your visit
  1. 01

    Freezing and isolation

    Local anesthetic goes in first. Once the area is numb, the tooth gets isolated from the rest of your mouth so the working area remains clean.

  2. 02

    Opening and clearing

    A small access point is made so the dentist can reach the inside of the tooth and take out the tissue that has been affected.

  3. 03

    Cleaning and sealing

    Each canal is instrumented, disinfected and prepared. Once ready, the system is filled to help keep bacteria from coming back in.

  4. 04

    Rebuilding the tooth

    A filling and frequently a crown come last. This step restores function and shields a tooth that may now be more prone to fracture.

To help you follow along

Plan your questions around the steps.

A list of stages is general, whereas your tooth is specific. It makes sense to ask how the sequence will apply to you before anything begins.

Ask when each stage is expected to happen, so that you can arrange your calendar and talk through estimated costs ahead of time.

Questions for each stage

  • How many appointments does this particular tooth appear to need?
  • Which stages would happen at each of those visits?
  • What kind of final restoration would suit this tooth, and when should it go on?
  • What should I tell you about my medications, health history, and insurance or CDCP?

Knowing where you are

Ask for a running commentary.

Some patients want every stage narrated while others prefer quiet. Tell us which you like. It is your appointment, and knowing what is underway may make it easier to settle in.

Sensations along the way

Vibration and pressure are things you may notice while the tooth is numb.

Interrupt if something is sharp

Sharp pain is not something to sit through, and the dentist needs to know right then.

Agree how to get our attention

With instruments in your mouth, talking is awkward, so settle on a hand signal beforehand.

The stage after the last stage

What comes once the work is complete.

Your involvement carries on for a while. Recovery and upkeep are simply the last links in the chain, and knowing them in advance makes them less of a surprise.

01

A tender bite at first

For a short period, chewing on that side may feel tender. This is expected to improve, and worsening or marked pain should prompt a call.

02

Finish the sequence

If your crown or other final restoration is still to come, keep that appointment. The tooth stays vulnerable until the plan has been completed.

03

Ongoing care

Treated teeth can still develop leaks, cracks or fresh decay. Going on with regular dental visits helps you protect the result.

Ask our team
What is the first step for someone from Templeton-Sinclair?

Start with an assessment request by phone at (204) 338-3003 or through this page’s form. Once a time is confirmed, you would come to Unit 5, 2358 McPhillips Street for the examination.

Which stage is the most uncomfortable?

That differs between people, and the inflammation already present can influence how a tooth feels. The area is numbed before work starts, and anything sharp should be mentioned without delay.

What actually fills the canals?

A sealing material is placed once the canals are clean and shaped. Ask the dentist to describe what will be used for your tooth if you would like more detail.

Is the tooth finished once the canals are sealed?

Not yet. It still requires a final restoration, which is often a crown for a back tooth. Consider the sealing a milestone rather than the finish line.

Can you tell me in advance how many stages happen per visit?

After examining the tooth, the dentist can describe the anticipated sequence. Complex anatomy or active infection may add visits, so that outline could change as treatment moves along.

Ready for step one?

It begins with an examination.

The opening stage is a visit to our Winnipeg clinic, which you can request here. If you are dealing with severe pain or swelling, a phone call is the right way to reach us.
