Inlays & Onlays for West Kildonan Residents

Hearing that a cavity has outgrown a simple filling can catch you off guard. If you live in West Kildonan, this page explains what that finding may mean for a back tooth and what happens next.

Moderate decay, explained

What Happens When a Filling May Not Be Enough

Decay that reaches well across a molar leaves less sound tooth around the hole. A direct filling is shaped right in the mouth and suits smaller repairs. Once the space becomes extensive, a piece custom-made outside the mouth may give more controlled shape and support.

That piece is an inlay or an onlay, and neither one is automatic. West Kildonan is an area in Winnipeg, and residents who want this looked at are seen at Winnipeg North Dental on McPhillips Street, where the dentist weighs how much healthy structure surrounds the decay.

Size matters here

How far the cavity spreads shapes whether a direct or a custom repair makes more sense.

Sound walls count

Healthy tooth left around the decay is a large part of what makes partial coverage workable.

Decay comes out first

All damaged material is cleared away before anything is recorded for the custom piece.

Sorting the options

Three ways a decayed molar might be rebuilt.

A larger cavity does not lead to one fixed answer. Which repair suits you depends on what remains once the decayed part has been dealt with.

If an inlay is suggested

Decay confined to the central chewing area, with the raised cusps still strong, may point toward a custom piece seated inside them.

  • The cusps stay as your own natural tooth.
  • It takes the place of the area hollowed out by decay.
  • Surrounding walls have to be judged suitable first.

If an onlay is suggested

Sometimes the cavity has undermined a cusp. An onlay then reaches over that weakened part and leaves the other surfaces uncovered.

  • Coverage extends only to the cusps selected.
  • Stronger surfaces can stay untouched by the design.
  • Your bite is factored in when the shape is planned.

A filling or a crown could still turn out to be the right call. Decay may also look different on examination than it did at first glance, so the plan can only be settled after assessment.

From finding to finished

What follows the news about your cavity.

Custom work moves through more stages than a direct filling does. Knowing the order can make the recommendation easier to absorb.

Request your visit
  1. 01

    Measure the problem

    Cracks, leftover walls, the depth of decay, root health and your bite are all reviewed. You hear which repair looks suitable and why.

  2. 02

    Clear the decay

    Freezing is usually used for this part. The dentist removes what is damaged and shapes a clean space that can support the restoration.

  3. 03

    Record the space

    Next comes a scan or impression capturing the tooth, how it meets its neighbours, your bite and a shade. A temporary may go on if the piece is made between visits.

  4. 04

    Seat the piece

    Fit and bite get checked before anything is permanent. After that, the restoration is bonded adhesively and given a polish.

Getting ready to decide

Bring what you were told about the cavity.

Maybe the finding came up during a routine exam, or perhaps you noticed something yourself. Either way, sharing the background gives the dentist a useful starting point for this tooth.

Recent X-rays held by another clinic may be relevant, so ask about having them transferred when you request your visit.

Worth noting down beforehand

  • Which tooth was flagged, and who flagged it.
  • Any twinges with cold, sweets or chewing on that side.
  • Medications you take and updates to your health history.
  • Whatever dental plan or CDCP information applies to you.

Taking in the news

It is fine to feel unsure about a larger repair.

Being told a tooth needs more than you pictured can be unsettling. Ask anything you like, including what would change if you chose to wait.

Freezing for preparation

Local anesthetic is the usual approach while decay is being removed, so tell us about past experiences with it.

Sensitivity afterward

Some temporary tenderness can follow, and it ought to get better. Let the clinic know if it does not.

Room to process

You are welcome to ask how soon this tooth should be dealt with before you commit to anything.

Keeping new decay away

Protect the tooth you just had rebuilt.

A restoration cannot decay, though the natural tooth beside it still can. That makes daily habits a real part of how long the repair serves you.

01

Mind the margin

New decay can begin along the seam between restoration and enamel, so give that edge careful brushing and flossing.

02

Report odd changes

A high-feeling bite, a sharp edge, or any shifting of the piece should prompt a call to us.

03

Return for exams

Ongoing check-ups let the dentist keep watch on the restored tooth along with the rest of your mouth.

Ask our team
Can someone from West Kildonan come in about a large cavity?

Yes. Send the request form or phone (204) 338-3003 and mention the tooth concerned. Appointments happen at Unit 5, 2358 McPhillips Street, Winnipeg, MB R2V 4J6, once the office has arranged a time with you.

How big does a cavity have to be before a filling stops being suitable?

No set measurement applies. A dentist considers how extensive the filling would be, how predictable it might be, and what healthy tooth would be left to support it.

Can I just ask for a large filling instead?

By all means raise it. Tell the dentist you would prefer this and ask how each choice would likely affect your particular tooth, so that you understand the trade-offs.

Will the decay be gone once the restoration is on?

The decayed material is removed during preparation, before the piece is made. New decay can still form later, particularly at the margins, which is why home care remains important.

What happens if the decay turns out to be deeper than it appeared?

The plan may need revisiting. Root health and the amount of remaining tooth both feed into whether partial coverage still suits, and the dentist can explain any change.

Is there a temporary after the cavity is prepared?

There may be, when the piece is being made between visits. Temporaries are less durable than final restorations, so follow the care instructions you are given.
