Decay does not always stop at a depth a simple filling can handle. Here is why a cavity can turn into a bigger conversation, and what that conversation is likely to cover.
Let's find a time
Decay works its way inward, through enamel and then dentin, toward the pulp at the centre of the tooth. As long as that inner tissue is healthy, repairing the outer layers may be enough. Once it is irreversibly inflamed or infected, patching the outside no longer addresses the source of the problem.
That is often when root canal therapy enters the discussion. For Margaret Park residents, who live in an area of Winnipeg, this assessment takes place at our McPhillips Street clinic. An examination and X-rays help the dentist judge how far decay has travelled and what your tooth now needs.

How close decay has come to the inner tissue shapes what treatment makes sense.
A deeply decayed tooth may cause little discomfort, or quite a lot, before it is examined.
When enough sound structure remains, treatment aims to keep your natural tooth working.
One rebuilds the outside of a tooth, while the other treats the inside as well. The right one depends on the health of the pulp.
A filling replaces tooth structure lost to decay, and it suits teeth whose inner tissue is not the source of trouble.
Treatment goes further by removing affected tissue from within the tooth before it is restored.
A cavity alone does not mean you need a root canal. Only an examination and appropriate X-rays can say what is going on in your tooth.
You should understand what has been found before deciding anything, and appointment numbers vary depending on the tooth and the planned restoration.
Request your visitA dark spot, a rough edge, food catching or a twinge when eating are all useful to mention, as is how long you have noticed them.
Examination and X-rays give the dentist a sense of how far decay has progressed and how much of the tooth is sound.
You hear whether a filling may still be enough, whether the pulp appears affected, and whether the tooth can be predictably restored.
If root canal therapy is the agreed path, the canals are treated first with the area numbed, and a suitable restoration follows.
Hearing about a root canal when you expected a filling can be jarring. Asking the dentist to show you what they saw on the X-ray is a perfectly reasonable request.
Because the two treatments differ, ask for estimated costs of whichever is recommended, along with any final restoration it requires.
The waiting area and consultation room at our clinic.
Decay does not always announce itself, and life can get in the way of dental visits. Your time here is for understanding the tooth and deciding what to do about it, not for going over what might have been.
An X-ray can make a hidden problem easier to grasp, so ask to have yours explained.
Treatment begins with local anesthetic. Please mention right away if you feel anything sharp.
It is easier to talk through a fear about the procedure before it starts than during it.
Once the deep decay is dealt with
A repaired tooth still lives alongside the rest of your teeth, and the same risks that affected it may matter elsewhere in your mouth.
Decay and treatment both leave a tooth with less natural structure. Restoring it as advised is how you guard against a fracture later.
The nerve may be gone, but the outside of a treated tooth can still decay. Keep brushing and cleaning around that tooth as you would any other.
Regular check-ups give the dentist a chance to find a developing cavity while the available treatment may be simpler.

A filling repairs what is missing from the tooth, but it does not treat diseased tissue inside. If the pulp cannot recover, closing over it would leave the actual problem in place.
Your symptoms, the examination and X-rays are considered together. Lingering pain after hot or cold, tenderness on biting or a gum bump can all be clues, though none settles the matter alone.
It could be, as damage can reach the inner tissue before severe pain begins. Likewise, not every sore tooth needs a root canal, which is why it needs to be examined.
Continuing decay can reduce the structure available for a restoration, and a tooth that can no longer be restored may need removal. Ask how much time your own tooth seems to allow.
