What Is a Dental Crown?

A dental crown is a custom-made cap that fits completely over a damaged or weakened tooth, encasing it from the gum line up to restore its original shape, size, strength, and appearance. Once cemented in place, a crown functions exactly like a natural tooth, it is fixed, non-removable, and indistinguishable from the surrounding teeth when made from porcelain.

When Is a Crown Needed?

Crowns are one of the most versatile restorative treatments in dentistry and are recommended in a range of situations.

A crown is typically needed when a tooth is cracked, fractured, or broken in a way that cannot be adequately repaired with a filling, particularly when the crack extends toward or below the gum line. Leaving a cracked tooth untreated risks the crack deepening, which can ultimately lead to the need for root canal treatment or extraction.

Crowns are the standard restoration following root canal therapy, as the treated tooth is significantly weakened by the procedure and requires full coverage to protect it from fracture under biting forces.

A tooth with extensive decay, where so much of the original structure has been lost that a filling would not have sufficient tooth structure to bond to, is best restored with a crown, which distributes biting forces evenly across the entire tooth rather than relying on a small bonded area.

Crowns are also used to restore dental implants, to anchor the ends of a dental bridge, to protect a tooth that has become severely worn from grinding or acid erosion, and as part of cosmetic smile makeovers where a significant change to tooth shape or size is desired alongside or instead of veneers.

What Materials Are Crowns Made From?

Eastern Dental Group uses high-quality porcelain and ceramic materials for crowns on visible teeth, as these most closely mimic the translucency and light-reflecting properties of natural enamel. Porcelain-fused-to-metal crowns, which have a metal substructure with a porcelain outer layer, offer good durability and are sometimes used for back teeth. Full metal crowns in gold or other alloys are occasionally recommended for back teeth where maximum durability is the priority and aesthetics are less critical.

Your dentist will recommend the most appropriate material for your specific tooth, its position in the mouth, and your bite forces.

What Is a Dental Bridge?

A dental bridge is a fixed restoration used to replace one or more missing teeth. It consists of one or more artificial teeth, called pontics, suspended between crowns that are placed over the natural teeth on either side of the gap. The bridge is cemented permanently in place, restoring the appearance of the smile and the function of the missing teeth without any removable component.

When Is a Bridge Recommended?

A bridge is an appropriate tooth replacement option when one, two, or occasionally three adjacent teeth are missing, the neighbouring teeth on either side of the gap are healthy and strong enough to support the bridge, and the patient prefers a fixed restoration over a removable option such as a partial denture.

The primary consideration with a traditional tooth-supported bridge is that the adjacent teeth must be prepared, a layer of enamel is removed from each abutment tooth to accommodate the crown that will anchor the bridge. These teeth will always require some form of coverage going forward. For patients with healthy, intact neighbouring teeth, an implant-supported crown or implant-supported bridge may be preferable, as it replaces the missing tooth without involving the adjacent teeth at all. Your dentist at Eastern Dental Group will discuss both options and their respective trade-offs at your consultation.

Implant-Supported Bridges

Where multiple adjacent teeth are missing and dental implants are placed at either end of the gap, an implant-supported bridge can span the space without using natural teeth as anchor points. This avoids preparation of healthy teeth and provides a more stable, bone-preserving solution than a conventional tooth-supported bridge.

Why Replacing a Missing Tooth Matters

Leaving a gap unfilled after a tooth extraction has consequences beyond aesthetics. The adjacent teeth begin to tilt and drift toward the space over time, disrupting the bite and creating areas that are difficult to clean and at higher risk of decay and gum disease. The tooth in the opposing jaw, the one that used to bite against the missing tooth, can also begin to over-erupt, growing into the gap. A bridge placed promptly after extraction prevents these changes from occurring and maintains the structural integrity of the surrounding dentition.
