Root Canal Therapy for Southdale Residents

You paid to protect that tooth, so it can feel unfair when it starts hurting anyway. A crown shields the outside, but the tooth beneath it is still living tissue that can run into trouble.

The tooth beneath the cap

When a Crowned Tooth Starts to Hurt

Unless it has already had canal treatment, a crowned tooth still contains its soft inner tissue. Past damage may have taken a toll on that tissue years ago, and decay can also creep in along the crown’s edge. The crown itself might look perfectly sound while any of this is taking place.

Living in Southdale, an area in Winnipeg, you can have this checked at our clinic on McPhillips Street. The dentist can examine the tooth, look at X-rays and talk about whether canal treatment makes sense, and what would then happen with the crown you already have.

A crown isn’t a seal on everything

It covers the visible tooth while its inner tissue remains capable of becoming inflamed.

Soreness has many causes

The problem could be the pulp, your bite, the gum or something else entirely.

Your crown needs a look too

Its fit and condition help determine what should happen to it next.

Working around a crown

What’s different with a cap in place.

Your treatment follows the usual stages, with one extra question added: how does the dentist get to the canals when a crown is covering the tooth?

Why a crowned tooth can act up

A tooth that needed a crown has generally been through something already.

  • Earlier decay or a fracture may have harmed the pulp.
  • New decay can develop where the crown meets the tooth.
  • Leaks at the margin can let bacteria reach the inside.
  • A crack beneath the crown may stay out of sight.

How treatment could proceed

Sometimes a small opening can be made through the crown itself, and sometimes it can’t.

  • Freezing and isolation come first, as they would with any tooth.
  • Access is gained to the affected tissue inside.
  • Canals are cleaned, disinfected, shaped and then filled.
  • The access opening is repaired, or a new crown is planned.

Whether your existing crown can stay depends on how it fits and how sound the tooth is beneath it, so ask about this directly.

Questions for the exam

Getting clear on the crown.

Knowing what’s causing the pain is only half of it. You’ll also want to learn what any treatment means for the crown you already have.

Request your visit
  1. 01

    Share the crown’s history

    Roughly when it was placed, why it was needed and whether it has ever felt different are all useful to know.

  2. 02

    Have it tested and imaged

    X-rays can’t see through everything, but along with other checks they help narrow down what’s going on.

  3. 03

    Ask what happens to the crown

    Find out if it may stay, needs repair where it’s accessed or would need replacing altogether.

  4. 04

    Compare the alternatives

    If the tooth under the crown can’t be restored predictably, removing it may come into the conversation.

Digging up the details

What may help the dentist.

You don’t need the paperwork on your old crown. Whatever you recall can help, along with the current picture of your health.

If your crown feels loose or comes off, phone the clinic and explain what happened.

If you remember

  • How long the crown has been in place, even approximately.
  • Whether that tooth has ever had a root canal already.
  • Changes you’ve noticed, like soreness when you bite or a bad taste.
  • Your up-to-date medicines, allergies and health conditions.

What this may feel like

Treatment on a covered tooth.

Numbing works in much the same way on a tooth with a crown. Here’s what you could notice in the chair, keeping in mind that responses vary.

Sensations through the crown

Vibration may seem stronger as work takes place through a harder material. Please mention anything that feels sharp.

Keeping your mouth open

Your jaw can tire after a while, so ask for a break if you’d like one.

The effect of inflammation

Inflammation in place before you came in may influence comfort both during and after your appointment.

With the canal work behind you

Getting the crown sorted.

Finishing up matters even more when the crown has been accessed or removed. Leaving an opening or temporary repair in place too long can undo good work.

01

Short-term soreness

It might be tender to chew on for a bit, and that should settle. Tell the clinic if pain or swelling becomes significant or is increasing.

02

Sealing the access point

Anywhere the crown was opened needs a sound repair, since leakage is one of the ways contamination gets back in.

03

Watching the edges

Decay at the margin of a crown can start quietly, so careful cleaning and routine exams remain important here.

A replacement crown, if needed, gets planned around what’s left of the tooth and how you bite.

Helpful details about root canal therapy in Southdale.

Ask our team
How would someone in Southdale ask about a sore crowned tooth?

Tell us about the crown when you phone (204) 338-3003 or write in. The exam would be at 2358 McPhillips Street in Winnipeg.

Does my crown have to come off for a root canal?

Not always. An opening through it might be possible, depending on the fit and the condition of the tooth. The dentist can explain after looking at yours.

Could the crown be fine while the tooth is failing?

It can happen. The visible part might be intact while problems develop at the edge or inside, so the crown’s appearance isn’t a reliable sign by itself.

Is it the crown that’s making my bite feel high?

It might be, particularly if the crown is recent, but an inflamed tooth can also feel high or tender. An exam can help distinguish between these.

Will I need to pay for a whole new crown?

Whether you’d need one isn’t known until the tooth has been assessed. Ask for an estimate once the plan is clearer, covering any restoration.

My crowned tooth already had a root canal. Could it still hurt?

Yes, as treated teeth can develop new problems from leakage, a fracture, complex anatomy or decay. Have it examined so the cause can be looked into.

A crown shouldn’t ache

Have that tooth looked at.

Ask for an assessment at our Winnipeg clinic and tell us about your crown. If severe pain or swelling is involved, it’s better to phone.
