A tooth that was already fixed can still develop a problem underneath. Here’s what that means for Kildonan residents, with treatment on McPhillips Street.
Let's find a time
It can feel unfair to hear that a filled tooth has a cavity. A filling replaces lost structure, yet the natural tooth meeting it stays vulnerable. Decay can get going along that boundary or beneath the older material, often without any pain to warn you.
If this turns up, Winnipeg North Dental will explain where it appears to be and what a repair would involve. The old material generally has to come out so the area can be properly treated. How much remains afterward helps decide whether another filling is suitable.

Trouble below an old repair doesn’t necessarily come with symptoms.
It usually comes out so the affected part beneath can be reached.
Remaining healthy tooth shapes which restoration is appropriate.
You can’t inspect beneath a restoration yourself. Clues may be subtle, and an assessment is needed to work out what’s really responsible for them.
Each of these has other potential explanations, so none proves there’s decay below the filling.
Looking and feeling alone can’t always answer the question, which is why appropriate records may be involved.
The full extent sometimes becomes clear only after the old material is out. If that changes the recommendation, you’d be told what has been found and why.
First comes confirmation of the tooth and a review of the plan. The exact sequence varies by tooth and material, but a replacement direct filling typically runs this way.
Request your visitLocal anesthetic is given if appropriate. Attention then turns to isolating the tooth, since moisture interferes with placing the material.
Taking out the previous filling exposes what’s below. Affected structure is cleared away, sparing healthy tooth whenever that can be done.
Tooth-coloured material is brought up in controlled layers and hardened between them, recreating contours you can clean around.
Your teeth are brought together to check contact. High spots get adjusted, and the surface is smoothed before you go.
Your memory of that tooth can help, even if it’s vague. Knowing roughly when it was filled, and what has changed since, gives the examination useful context.
If the recommendation came from an earlier visit, say what you were told. We’ll still need to assess the tooth ourselves before proposing treatment.
Reception and the consultation room in our Winnipeg clinic.
That earlier filling did a job, and needing another repair isn’t a verdict on you. If this news is discouraging, tell us. We’re glad to slow down and go through what’s happening with this tooth.
Seeing the area on your records may help the explanation land.
You’re free to ask if freezing is expected for your particular repair.
Mention any discomfort during treatment so we can stop and reassess.
After the replacement
Aftercare is tailored to what was done. Beyond the first day, your attention belongs on that boundary between the restoration and natural tooth.
Wait for normal sensation before you chew anything, as the numb tissue is easily bitten. Treat hot drinks carefully during this stretch.
A brief reaction to temperature or pressure can happen after a repair. Look for gradual easing, and phone if it’s heading the other way.
Brushing plus cleaning between teeth reaches the edges where new decay can begin. Recommended exams allow the repair to be monitored.
A tooth that contacts first, or stays sore when chewing, is a good reason to give the clinic a call.

Helpful details about dental fillings in Kildonan.
Ask our teamThe natural tooth around a restoration can still decay, and older repairs may develop small openings at the margin. The process can move along quietly until it’s picked up at an examination.
Not by itself. Bite forces, diet, hygiene and time all influence a restoration, and new decay can arise years later. We can only speak to what the tooth shows now.
That depends on what’s found, though reaching the affected area often means taking out the old material. Ask how much would need to come out in your situation.
It may be, because some additional tooth might be affected. If too little healthy structure is left, an inlay, onlay or crown may be considered instead.
X-rays can reveal many changes that are hard to see or feel, but they’re one part of an assessment. They’re considered along with the examination and your symptoms.
You can fill out the form on this page or call (204) 338-3003 and mention the tooth. Assessments happen at 2358 McPhillips Street, and someone from the clinic will reply.
These treatments can come up if a filled tooth has lost more structure than a direct repair can support.
