Inlays & Onlays for St. Vital Residents

Cavities on the sides of back teeth often go unseen until an X-ray shows them. If you live in St. Vital and have heard this about one of your molars, our Winnipeg clinic can explain where an inlay or onlay might fit.

Why Side Decay Can Call for More Than a Small Filling

Where two back teeth touch, food and plaque can sit undisturbed, and decay can spread before anything is felt. Reaching it usually means working through the chewing surface, so the repair may end up larger than the spot first suggested.

When the opening becomes substantial, a custom restoration can rebuild the side wall and the contact with the neighbouring tooth. Anyone in St. Vital, which is part of Winnipeg, who has been told about a hidden side cavity can have it reviewed at Winnipeg North Dental on McPhillips Street.

A tight contact

Rebuilding the side of the tooth aims to restore how it meets the tooth beside it.

Controlled shape

Because it is made outside the mouth, the restoration’s contour can be shaped precisely.

Assessment first

Whether a filling, an inlay, an onlay or a crown suits depends on what remains.

Options for a side cavity

How much of the tooth is affected shapes the choice.

Once decay between teeth has been removed, the dentist sees how strong the remaining walls and cusps are. That view guides which design is reasonable.

Restoring with an inlay

If the cusps remain sturdy, an inlay can replace the lost side wall and part of the chewing surface without covering the cusps.

  • Rebuilds the side where decay was removed.
  • Restores the contact with the neighbouring tooth.
  • Leaves sound cusps uncovered.

Restoring with an onlay

When removing side decay leaves a cusp thin or weak, an onlay can cover that cusp as well, keeping the rest of the tooth natural.

  • Adds coverage over weakened cusps.
  • Still preserves surfaces that are healthy.
  • Is fitted with your bite in mind.

Decay sometimes affects both teeth that share a contact. Ask whether the neighbouring tooth was also checked and what it might need.

Step by step

From finding the cavity to a finished contact.

This is the general sequence. A temporary may protect the tooth if the restoration is made between visits.

Request your visit
  1. 01

    Confirming the extent

    How far the side decay has spread, whether cracks run through the tooth, how thick the walls are, how you bite and how the root looks all feed into the suggested design.

  2. 02

    Removing the decay

    Once frozen, the tooth is opened from above so the hidden cavity on its flank can be cleaned out and the space formed for a made-to-fit piece.

  3. 03

    Recording the contacts

    Particular attention goes to the side facing the neighbour when the prepared tooth is scanned or an impression is made, along with your bite and a matching shade.

  4. 04

    Placing the restoration

    Floss may be passed through the rebuilt contact while the piece is tried, so its tightness can be judged before it is bonded and polished.

Signs you may have spotted

Clues that point to decay between teeth.

Side cavities do not always cause symptoms, but these observations can still be helpful to share.

Should the side of the tooth crumble or start to throb before your appointment, phone the clinic instead of filling in the form.

Have you noticed

  • Floss catching or tearing between two back teeth.
  • Food packing into one spot after meals.
  • Sensitivity on one side when eating something sweet or cold.
  • Any medicines you take and health conditions you have.

Frozen for the side work

Numbing makes the preparation easier.

Cleaning decay from between teeth is normally done with the area frozen. When the numbness lifts, the restored side may feel tender for a while before it quietens.

Freezing the area

Both the tooth and the gum next to it are numbed so the side can be worked on comfortably.

Protecting it meanwhile

A temporary, if used, is not as strong as the final piece, so be gentle with it.

Sensitivity that fades

It is common for a restored tooth to react for a while before settling down.

Keeping the contact clean

The spot between teeth still needs care.

Restoring the side of a tooth does not stop new decay from forming there. Cleaning between teeth daily matters as much as it did before.

01

Clean between daily

Floss or another between-teeth cleaner should pass the restored contact each day.

02

Notice food trapping

If food starts packing into the restored contact, mention it at your next visit or call.

03

Call when something changes

Floss that suddenly snags on a new ledge, a tooth that lands first when you close, a twinge that will not fade or a piece that moves are reasons to phone.

A rebuilt side has no promised service life. Its future turns on the tooth left around it, careful shaping and bonding, keeping saliva out during bonding, your bite and grinding, cleaning between teeth and whether decay starts again at that contact.

Your questions, answered.

Helpful details about inlays & onlays in St. Vital.

Ask our team
Why does decay between teeth need work through the top of the tooth?

The side surface is hidden by the neighbouring tooth, so access usually comes from above. That can make the opening larger than the cavity itself.

Can an inlay restore the contact with the next tooth?

Yes, a custom piece can be shaped to rebuild the side wall and meet the neighbouring tooth. The fit of that contact is checked before bonding.

Why might my side cavity need an onlay instead?

If removing decay leaves a cusp thin or undermined, covering it can provide added support. The dentist decides once the tooth has been prepared.

Is it possible both teeth have decay where they touch?

It can happen. Ask whether the tooth next door was examined and what the dentist found.

Will food stop catching there after treatment?

Restoring a proper contact may help, but it cannot be promised. Tell the dentist if food packing continues afterward.

I live in St. Vital and was told about side decay elsewhere. Can I be seen?

You can ask for an assessment on this page or call (204) 338-3003. Your visit would be at Unit 5, 2358 McPhillips Street, Winnipeg, MB R2V 4J6 once confirmed.
