Dental Crowns vs Bridges: Which Option Is Best for a Missing Tooth?

Dental Crowns vs Bridges

TL;DR

A dental crown caps and protects a single damaged tooth, while a dental bridge replaces one or more missing teeth by anchoring an artificial tooth to the crowns on either side. If your tooth is still present but weak, cracked, or heavily decayed, a crown is usually the answer. If the tooth is already missing, you’re choosing between a bridge and a dental implant. Bridges are faster and less invasive but rely on healthy neighbouring teeth, while implants stand alone and typically last longer. This guide breaks down the process, cost, and longevity of each so you can have an informed conversation with your dentist before deciding.

What Is a Dental Crown?

A dental crown is a custom-made cap that fits over an existing tooth to restore its shape, strength, and appearance. Crowns are one of the most common restorative treatments in general dentistry, and at our Camberwell practice they’re typically used when a tooth is too damaged for a filling but doesn’t need to be removed entirely.

When a crown is used:

  • After a root canal, to protect the treated tooth from fracturing
  • On a tooth with a large filling that no longer has enough natural structure to support it
  • To repair a cracked, chipped, or worn-down tooth
  • To cover a discoloured or misshapen tooth for cosmetic reasons
  • As the visible cap placed over a dental implant

The process:
Getting a crown usually takes two visits. In the first, your dentist prepares the tooth by removing a thin layer of enamel to make room for the crown, takes an impression or digital scan, and fits a temporary crown while your permanent one is made. At the second visit, the permanent crown — commonly made from porcelain, ceramic, or a metal-porcelain blend — is checked for fit and bite, then cemented into place.

If you’re weighing up porcelain crowns in Camberwell, porcelain is popular because it closely matches natural tooth colour and holds up well under normal biting pressure, making it a strong option for both front and back teeth.

What Is a Dental Bridge?

A dental bridge is used specifically to replace one or more missing teeth. It consists of a false tooth (or teeth), called a pontic, held in place by crowns fitted over the natural teeth on either side of the gap — known as abutment teeth.

When a bridge is used:

  • To replace a single missing tooth without surgery
  • To replace several missing teeth in a row
  • When the adjacent teeth already need crowns or are structurally strong enough to support one
  • As a faster alternative to implants for patients who want a shorter treatment timeline

The process:
Similar to a crown, a bridge typically requires two appointments. The abutment teeth are shaped to receive crowns, an impression is taken to design the pontic and connecting crowns as one piece, and a temporary bridge is worn in the interim. On the second visit, the permanent bridge is fitted, adjusted, and cemented in place.

Which Is Better for a Missing Tooth? A Decision Guide

Because a crown restores an existing tooth and a bridge replaces a missing one, they’re not always interchangeable — but when you’re missing a tooth, a bridge and a dental implant become the real comparison. Here’s a general guide:

Consider a bridge if:

  • The teeth next to the gap are already weakened or have large fillings and could benefit from crowns anyway
  • You want a non-surgical option
  • You’re not a suitable candidate for implant surgery
  • You want a shorter overall treatment time

Consider an implant instead if:

  • The teeth next to the gap are healthy and you’d prefer not to alter them
  • You want the longest-lasting, most independent solution
  • Bone density in the area is sufficient to support an implant (or can be built up)
  • You’re comfortable with a longer treatment timeline

There’s no universally “best” answer — it depends on the condition of your remaining teeth, your budget, your bone health, and how you weigh a shorter treatment time against long-term durability. Your dentist can assess your specific situation and talk through which option makes the most sense for your mouth.

Cost Comparison: Crown vs Bridge vs Implant

Costs vary depending on the materials used, the number of teeth involved, and the complexity of your case. The table below gives a general indication for patients researching dental bridge cost in Camberwell and tooth crown cost in Camberwell.

TreatmentTypical Price Range (AUD)What’s Included
Single dental crown$1,500 – $2,500Tooth preparation, impression, custom-made crown, fitting
Dental bridge (3-unit)$3,500 – $6,500Two abutment crowns, one pontic, fitting
Single dental implant$4,000 – $6,500+Implant post, abutment, and crown (may require separate stages)

These figures are general estimates only and can vary based on individual clinical needs. The most accurate way to understand your cost is with a personalised quote following an examination and consultation.

Longevity: How Long Does Each Option Last?

  • Dental crowns generally last 5 to 15 years, depending on the material, your oral hygiene, and habits like teeth grinding. Porcelain crowns can last well over a decade with good care.
  • Dental bridges typically last 10 to 15 years, though their lifespan is closely tied to the health of the abutment teeth supporting them. If those teeth develop decay or gum issues, the bridge may need earlier attention.
  • Dental implants are the most durable option, often lasting 25 years or more, and in many cases a lifetime, since the titanium post fuses with the jawbone. The crown on top may eventually need replacing, but the implant itself is built for the long term.

Regular check-ups, good brushing and flossing habits, and avoiding excessive grinding or chewing on hard objects will help extend the life of any of these restorations.

Dental Implants as a Long-Term Alternative

For many patients missing a single tooth, a dental implant is worth considering alongside a bridge. Rather than relying on neighbouring teeth for support, an implant is anchored directly into the jawbone, which also helps preserve bone density in the area — something bridges and dentures can’t do.

Implants involve a longer process, usually spanning several months to allow for healing and osseointegration (the fusing of the implant with the bone), but they offer a stand-alone, long-lasting solution that doesn’t require altering healthy adjacent teeth.

If you’re missing multiple teeth or considering options beyond crowns, bridges, and implants, it’s also worth exploring dentures as a removable alternative, particularly for more extensive tooth loss.

FAQ

Can a dental bridge be used for more than one missing tooth?

Yes, bridges can replace multiple missing teeth in a row, though the more pontics involved, the more strain is placed on the abutment teeth. Your dentist will assess whether a bridge is suitable or if implants might better distribute the load.

Both procedures are performed under local anaesthetic, so you shouldn’t feel pain during the appointment. Some sensitivity around the treated area is normal for a few days afterwards.

As a general rule, if more than half the tooth structure is compromised, a crown offers better long-term protection than a filling. Your dentist can determine this with an examination and, if needed, an X-ray.

Many private health funds offer partial cover for major dental work like crowns and bridges under extras cover, but the amount varies by policy and provider. It’s best to check directly with your fund for your specific level of cover.
