What Is a Dental Crown and When Is One Needed?
A crown is a custom cap that covers a tooth on all sides, restoring its shape, strength, and appearance. Where a filling replaces part of a tooth, a crown wraps the whole thing, which is what stops a weakened tooth from splitting under chewing force. Dr. Abbas recommends one when there is not enough sound structure left for a bonded restoration to hold.
The usual reasons at our Brampton office are:
- A tooth that has fractured or has a crack running through it
- A back tooth after root canal therapy, which becomes brittle without coverage
- A very large old filling that has left thin, unsupported walls
- Decay too extensive for a filling to restore predictably
- A tooth worn down significantly by grinding
- The restoration on top of a dental implant
What Materials Does Brampton Smiles Use for Crowns?
The material is chosen for the position of the tooth and the forces on it, not by a blanket policy. Dr. Abbas will explain the trade-off for your specific tooth before anything is prepared.
- Zirconia. Extremely strong, the usual choice for molars and for patients who grind. Modern layered zirconia is far more natural-looking than early generations.
- Lithium disilicate (all-ceramic). The best light behaviour and the most lifelike result, favoured for front teeth and premolars.
- Porcelain fused to metal. A long-serving option with a metal substructure for strength and a porcelain exterior for appearance.
- Full gold or metal alloy. Rarely requested now, but still the kindest material to opposing teeth and excellent where clearance is limited.
Getting a crown does mean reducing the tooth to make room for the material, and thicker materials require more reduction. That is one reason we do not default to the strongest option on every tooth.
What Is a Dental Bridge and How Does It Work?
A fixed bridge replaces one or more missing teeth by anchoring replacement teeth to the natural teeth on either side of the gap. The anchor teeth are crowned, and the replacement tooth spans between them. The whole unit is cemented, so nothing is removed for cleaning the way a partial denture is.
A bridge requires healthy, well-supported teeth on both sides of the space. Where those neighbouring teeth are pristine, Dr. Abbas will usually raise an implant as the alternative first, because a bridge means preparing two otherwise untouched teeth. Where the adjacent teeth already need crowns, a bridge often becomes the more sensible choice.
What Does Getting a Crown or Bridge Involve at Brampton Smiles?
Two appointments, typically 2 to 3 weeks apart, with a temporary in place between them.
- Preparation and scan (about 90 minutes). The tooth is frozen, shaped, and any weakened structure built up. A digital scan captures the preparation, the opposing arch, and the bite. A temporary crown is made and fitted before you leave.
- Lab fabrication (2 to 3 weeks). The crown or bridge is milled or pressed to the scan and finished by the technician.
- Fit and cementation (about 45 minutes). The temporary comes off, the fit and contacts and shade are verified, the bite is adjusted, and the restoration is cemented.
The appointment that decides whether a crown lasts is the second one, and specifically the bite check. A crown left a hair high takes every chewing force first, every time. That is what causes the sensitivity people assume is a failed root canal. We spend longer on articulating paper than most patients expect, and it is the cheapest insurance in the whole procedure.
How Long Do Crowns and Bridges Last?
Published literature commonly puts well-made crowns and bridges in the range of 10 to 15 years, with many lasting considerably longer. Longevity depends on three things far more than on material: the seal at the margin, the forces on the tooth, and how well the edge is cleaned at home.
What actually ends the life of most crowns is not the crown. It is new decay at the margin where the restoration meets the tooth, which is why flossing under bridges and around crown edges matters more than for a natural tooth. Grinding is the other major factor, and Dr. Abbas often recommends a nightguard for patients who clench.
Does Insurance Cover Crowns and Bridges at Brampton Smiles?
Most extended Canadian dental plans cover crowns and bridges under major restorative services, commonly at 50 percent and subject to your annual maximum. Frequency limits are typical, often one crown per tooth every 5 years. The Canada Dental Care Plan covers eligible patients for a range of restorative services.
Brampton Smiles runs a predetermination with your insurer before treatment starts, so the coverage answer is in writing rather than a guess. We direct-bill on the day and offer 0% in-house payment plans. See financing details.
“When a back tooth has had a root canal, the conversation I have is about timing, not about whether. That tooth is dehydrated and brittle, and it will hold up fine for a while, right up until the day it splits below the gum. A tooth I can crown is a tooth I can save. A tooth that has already split vertically usually is not.”
Frequently Asked About Crowns & Bridges at Brampton Smiles
Does getting a crown at Brampton Smiles hurt?
The appointment itself is comfortable under local anesthesia, and most patients describe it as similar to having a large filling. Mild tenderness in the gum around the tooth for a few days afterwards is normal. Sensitivity to cold on a tooth that has not had a root canal is common for a week or two and usually settles on its own.
Should I choose a bridge or a dental implant at Brampton Smiles?
It depends on the teeth beside the gap. If they are healthy and untouched, a dental implant is usually the better choice because a bridge means preparing two sound teeth. If those neighbouring teeth already need crowns, a bridge does two jobs at once. Bone volume, healing time, and medical history also factor in. Dr. Azher Abbas, DMD, reviews both options with you at consultation.
How do I clean under a bridge from Brampton Smiles?
A bridge is cleaned under, not just around. You will need a floss threader or superfloss to pass floss beneath the replacement tooth, or a water flosser, once daily. Plaque trapped under the span is the most common reason a bridge eventually fails. Our hygiene team demonstrates the technique at the cementation visit at our Brampton office.
My temporary crown came off. What should I do in Brampton?
Call Brampton Smiles at (905) 793-8668 the same day. Keep the temporary, avoid chewing on that side, and do not leave the prepared tooth uncovered for long, because neighbouring teeth can shift enough to affect the fit of the final crown. Re-cementing a temporary is a short appointment and we fit these in same day where possible.
Will a crown from Brampton Smiles match my other teeth?
Yes. The shade is selected against your natural teeth in good light, before the tooth dries out, since a dehydrated tooth reads lighter than it truly is. For front teeth, Dr. Abbas can request custom characterization from the lab. If you are planning to whiten, do it before the crown is made, because ceramic does not respond to whitening gel.
