When a tooth is damaged or missing, your dentist will explain options. Two common solutions are a crown and a bridge. They sound similar but serve different purposes. A crown covers and protects a single tooth. A bridge replaces one or more missing teeth by joining to nearby teeth. Both restore chewing and appearance. Both help your mouth work better. Choosing the right option depends on what’s wrong, the health of nearby teeth, and your long-term goals.
A clear way to remember it: a crown fixes one tooth. A bridge fills a gap. In this article we’ll explain how each works, when dentists recommend them, what the procedures involve, how long they last, costs, and what to expect from recovery. We’ll also mention local care options, including Pakenham Shine Dental and how to find the best dentist in Pakenham for crown and bridge in Pakenham work.
What is a dental crown?
A dental crown is a cap placed over a damaged tooth. The crown covers the visible part of the tooth above the gum line. Dentists use crowns to restore a tooth’s shape, strength and look. Crowns protect a weak tooth from breaking. They restore a tooth after a large filling or a root canal. Crowns can also cover a dental implant. Materials include porcelain, zirconia, metal, or a mix. Porcelain and zirconia look natural. Metal crowns are very strong and last long.
A crown is useful when the tooth structure is still present but weakened. For example, a large cavity or a crack may need a crown to keep the tooth functional. Your dentist will discuss which material fits your needs. A well-made crown blends with your other teeth and lets you chew normally.
What is a dental bridge?
A dental bridge replaces one or more missing teeth. It uses crowns on the adjacent teeth to hold an artificial tooth (called a pontic) in the gap. The two supporting crowns are called abutments. Together they form the bridge. Bridges restore the look of your smile and help with chewing and speech. They stop nearby teeth from shifting into the empty space. There are several types of bridges: traditional fixed bridges, cantilever bridges, and implant-supported bridges.
A traditional bridge needs healthy neighbouring teeth to support the crowns. That means those teeth are shaped to accept crowns. An implant-supported bridge uses dental implants as anchors instead of natural teeth. That avoids altering adjacent teeth but does require surgery and adequate bone.
When is a crown the right choice?
Choose a crown when one tooth is damaged but salvageable. Common reasons for crowns include:
-
Large cavities where a filling won’t hold.
-
A cracked or broken tooth.
-
A tooth that has had root canal treatment.
-
Cosmetic fixes for badly discoloured or misshapen teeth.
-
Covering a dental implant.
Crowns protect the tooth and can last many years with good care. They are a strong, predictable way to repair a single tooth.
When is a bridge the right choice?
Choose a bridge when a tooth is missing and the neighbouring teeth are strong enough to support the bridge. Bridges are a fixed, non-removable option. They are good when:
-
You want a quick, stable solution for one or two missing teeth.
-
You prefer not to have removable dentures.
-
You are not ready for implants due to cost, time, or medical reasons.
If neighbouring teeth already have large fillings or need crowns, a bridge can be an efficient way to both restore those teeth and replace the missing one.
How the procedures differ
Getting a crown is usually two visits. First, the dentist prepares the tooth, removes decay, and shapes it. An impression or digital scan is taken. A temporary crown protects the tooth while the lab makes the permanent crown. At the second visit, the crown is fitted and cemented.
A bridge often takes two to three visits. The dentist prepares the support teeth by shaping them for crowns. Impressions or scans are taken so the lab can make the full bridge. A temporary bridge protects the area until the permanent bridge is cemented. If an implant-supported bridge is chosen, the implant placement requires surgery and months of healing before the final bridge is attached.
The implant route takes longer but avoids changing healthy teeth. The right path depends on health, budget, and patient choice.
Impact on nearby teeth and jaw
A key difference is how each option affects neighbouring teeth. A crown treats a single tooth and usually does not change nearby teeth. A bridge requires reshaping of the supporting teeth. That means altering healthy teeth to secure the bridge. For some people this is acceptable. Others prefer to keep adjacent teeth untouched and choose implants instead.
Missing teeth can also affect the jawbone. When a tooth is lost, the bone in that area slowly shrinks. Implants help preserve bone because the implant acts like a root. Crowns and bridges restore function but don’t prevent bone loss unless an implant supports the restoration.
Longevity and maintenance
Crowns and bridges can last many years when cared for properly. Crowns often last 10–15 years, and bridges can last a similar time. Lifespan depends on material, oral hygiene, and habits like grinding teeth or chewing very hard foods.
Care tips: brush twice daily, floss once a day, and see your dentist for regular check-ups. For bridges, special floss threaders and interdental brushes help clean under the pontic. Poor hygiene can lead to decay under the supporting crowns or gum disease, which can cause bridge failure.
If you grind your teeth, ask about a night guard. Grinding shortens the life of restorations.
Cost differences
Costs vary by material, lab fees and whether implants are involved. Generally, a single crown costs less than a multi-unit bridge, because a bridge uses more materials and lab work. Implant-supported solutions are usually the most expensive due to surgery and parts. Insurance coverage varies. Ask your dentist for a clear estimate and payment options.
At Pakenham Shine Dental, we discuss costs upfront and offer options to fit different budgets. Talk to the clinic about payment plans or staged treatment if needed.
Aesthetic and functional considerations
Modern crowns and bridges are highly aesthetic. Porcelain and zirconia match tooth colour and shine. Good lab work makes restorations look natural. Functionally, both restore chewing and speech. A bridge fills the empty space so your smile looks complete. A crown restores the look of a damaged tooth.
If appearance matters most, your dentist will recommend materials and shades to match adjacent teeth. If strength is more important, especially for back teeth, materials like zirconia or metal may be better choices.
Risks and things to watch for
Both treatments are safe but have potential issues. After a crown, a tooth may feel sensitive for a few days. If discomfort continues, contact your dentist. In rare cases a crowned tooth later needs root canal treatment if infection develops. Bridges can fail if supporting teeth decay or become loose.
Always follow aftercare instructions. Report pain, looseness, or swelling quickly. Early action prevents bigger problems.
Choosing what’s right for you
Your dentist will recommend based on:
-
Number of missing teeth
-
Health of neighbouring teeth
-
Jawbone condition
-
Budget and time frame
-
Personal preference about altering adjacent teeth
A thorough exam, X-rays, and a candid discussion will guide the choice.

Questions patients often ask
Will it hurt?
You will get local anaesthetic. Most patients feel little to no pain during the procedure. Mild soreness may occur after.
How long does it take?
Crowns and bridges usually require a few weeks from start to finish. Implant options take longer due to healing time.
Can I switch from a bridge to implant later?
Yes. Bridges can be replaced by implants later if you decide to change.
How do I clean under a bridge?
Use floss threaders or interdental brushes to clean beneath the pontic.
Final thoughts
A crown repairs and protects one damaged tooth. A bridge replaces missing teeth by anchoring to nearby teeth. Both restore function and appearance. Implants add another long-term option that protects bone and avoids changing adjacent teeth. Which is best depends on dental health, personal goals, and budget.
