Crowns and bridges are fixed dental restorations that repair damaged teeth and replace missing ones. A dental crown is a custom-made cap that covers and protects a tooth that is badly decayed, cracked, weakened or heavily filled. A dental bridge replaces one or more missing teeth with artificial teeth held in place by the natural teeth next to the gap or by dental implants.
Both are common forms of dental tooth restoration. They can help you chew more comfortably, protect weakened teeth and restore the look of your smile. The key difference in dental crowns vs bridges is simple: crowns restore teeth you still have, while fixed dental bridges replace teeth you have lost.
How much healthy tooth remains, your gum health, your bite, where any teeth are missing and the condition of the surrounding teeth all decide whether either option suits you. Many people also wonder about comfort, appearance, durability and upkeep. This guide from Barton Dental in Hamilton answers those questions. For a personal recommendation, a dental assessment is the best first step, and you can learn more about our Dental Crowns in Hamilton.
What Are Dental Crowns and When Are They Needed?
A dental crown is a tooth-shaped restoration that fits over a prepared natural tooth to restore its shape, strength, function and appearance. A crown can also sit on a dental implant to replace the visible part of a missing tooth.
What a crown does
The crown covers the part of the tooth above the gum. It holds a weakened tooth together and protects it from further damage. The American Dental Association explains that crowns are used to strengthen weak teeth, restore broken teeth and cover implants.
Common reasons for a crown
- Extensive decay: when so much tooth has been lost that a filling would not hold.
- Cracked or broken teeth: to protect and restore the tooth, depending on where the crack is and how deep it goes.
- Large fillings: when little natural tooth remains and the tooth is at risk of breaking.
- After root canal treatment: back teeth in particular often need the extra protection. Learn more about our Root Canal Therapy service.
- Severely worn teeth: to rebuild shape and function.
- Appearance: when a crown is the right clinical choice for a badly shaped or discoloured tooth.
- Dental implants: an implant crown replaces a missing tooth.
Crown materials
| Crown Material | Main Characteristics | Considerations |
| Porcelain or ceramic | Tooth-coloured appearance | Suitability depends on the material and bite forces |
| Zirconia | Strong ceramic with tooth-coloured options | Appearance and choice vary by situation |
| Porcelain-fused-to-metal | Metal base with a porcelain outer layer | A dark line may show at the gum over time |
| Metal alloys | Very durable and resistant to breaking | Metallic look may not suit visible teeth |
| Resin-based materials | Often used for temporary crowns | Generally less durable than final ceramic or metal crowns |
No material is best for every tooth. Your dentist will consider the tooth’s position, your bite, how it will look and your clinical needs.
Benefits of crowns
Crowns can restore chewing, protect weak teeth, improve shape and appearance, support damaged teeth and help keep your bite comfortable.
When a crown may not suit
A crown may not be recommended if too little healthy tooth remains, the gums and bone are in poor condition or the damage makes the result unpredictable. Crowns restore existing teeth. They only replace a missing tooth when placed on an implant.
How Do Dental Bridges Replace Missing Teeth?
A dental bridge replaces one or more missing teeth by joining an artificial tooth to supporting teeth or implants on either side of the gap. Fixed dental bridges are cemented in place and are not removed at home.
Parts of a bridge
- Pontic: the artificial tooth that fills the gap.
- Abutment: the natural tooth or implant that supports the bridge.
- Retainer: the crown or attachment that connects the bridge to its support.
Designs vary with the type of bridge.
Types of bridges
- Traditional bridge: crowns are placed on the teeth on both sides of the gap, holding the pontic between them. The supporting teeth must be reshaped.
- Cantilever bridge: the bridge is supported on one side only. Bite forces, location and the supporting tooth decide suitability.
- Maryland (resin-bonded) bridge: the pontic is held by thin wings bonded to the back of neighbouring teeth. It may suit some front-tooth gaps.
- Implant-supported bridge: the bridge is attached to dental implants rather than natural teeth, which can be useful when several teeth are missing.
Your dentist will explain which types are suitable, and available, for your situation.
How bridges help
Bridges can help restore chewing, improve speech affected by gaps, fill visible spaces and make the dental arch more complete. They do not guarantee that teeth will never shift or that your bite will never change.
Who may be a candidate?
Your dentist will look at:
- How many teeth are missing and where.
- The condition of the neighbouring teeth.
- Gum health.
- Bone support.
- Your bite.
- Oral hygiene habits.
- Your preferences.
- Whether other options suit you better.
Bridges vs. other options
Dental Implants and removable partial Dentures are the main alternatives. Your oral health, budget, preferences and clinical situation decide which is best. Fixed dental bridges need a professional assessment and ongoing maintenance.
What Is the Difference Between Dental Crowns and Bridges?
The main difference between dental crowns and bridges is their purpose: crowns restore damaged teeth you still have, while bridges replace missing teeth. Traditional bridges often use crowns as anchors, so the two frequently work together.
| Feature | Dental Crowns | Dental Bridges |
| Primary purpose | Restore and protect an existing tooth | Replace one or more missing teeth |
| Tooth replacement | Can replace a tooth when placed on an implant | Replaces missing teeth with pontics |
| Support | Natural tooth or dental implant | Neighbouring teeth or dental implants |
| Tooth preparation | Usually needs the affected tooth reshaped | May need supporting teeth reshaped |
| Common indications | Extensive decay, fractures, weakened teeth, large fillings | Missing teeth and gaps |
| Cleaning | Regular brushing and cleaning between teeth | Regular brushing plus cleaning under the bridge |
| Lifespan | Varies with material, bite forces and care | Varies with support, design and care |
| Suitability | Depends on whether the tooth can be restored | Depends on the gap and supporting structures |
When a crown may be recommended
When your natural tooth is still there but needs extra protection or rebuilding, for example after a large filling, a fracture or root canal treatment.
When a bridge may be recommended
When one or more teeth are missing and you prefer or need a fixed replacement. Your dentist checks that the neighbouring teeth or implants can support it.
Can crowns and bridges be used together?
Yes. A traditional bridge usually includes crowns on the supporting teeth, which anchor the replacement tooth.
Which is better?
Neither. They do different jobs. Your dentist will consider your remaining tooth structure, the number of missing teeth, the condition of supporting teeth, gum health, bite forces, maintenance, your preferences and cost before recommending one.
What Happens During Crown and Bridge Treatment?
Crown and bridge treatment usually involves an examination, preparing the tooth or teeth, impressions or scans, a temporary restoration and fitting the final crown or bridge. The steps vary for crowns, tooth-supported bridges and implant restorations.
- Examination: Your dentist checks your teeth, gums and bite and takes X-rays to look at the roots, bone and any decay.
- Treatment planning: You discuss the recommended restoration, materials, appearance, stages and costs.
- Tooth preparation: For crowns and traditional bridges, the tooth or supporting teeth are reshaped to make room. How much varies with the design and material.
- Impressions or digital scans: These record the shape of your teeth and bite so the restoration fits.
- Temporary restoration: A temporary crown or bridge often protects the teeth while the final one is made.
- Fabrication: A dental laboratory makes the permanent crown or bridge to your dentist’s specifications.
- Fitting: Your dentist checks the fit, colour, bite and contact with neighbouring teeth, then cements or bonds it in place.
- Bite adjustments: Small adjustments may be needed. Tell your dentist if your bite feels uneven.
- Follow-up: A later check makes sure the restoration and gums are healthy.
Is getting a crown or bridge painful?
Not usually. Local anesthetic numbs the area while the teeth are prepared, so you may feel pressure or vibration but not pain. Some temporary sensitivity is common afterward. Persistent or worsening pain should be checked.
How long does treatment take?
Traditional crown and bridge treatment usually needs at least two appointments, with a temporary in between while the final restoration is made. The restoration and its complexity affect timing, so ask your dentist what to expect.
How Can You Care for Your Dental Crowns and Bridges?
Care for crowns and bridges with twice-daily brushing, daily cleaning between and under them, sensible habits and regular dental visits. The natural teeth and gums around restorations can still develop decay and gum disease.
Brush twice a day
Use a soft-bristled toothbrush and fluoride toothpaste, paying attention to the gumline around each crown.
Clean between teeth every day
Floss or use interdental brushes to remove plaque where a toothbrush cannot reach.
Clean under bridges
Plaque and food can collect under the pontic. Useful tools include:
- Floss threaders.
- Super floss.
- Interdental brushes when suitable.
- Water flossers as an extra aid.
Avoid very hard objects
Chewing ice, pens or very hard candy can crack restorations or surrounding teeth.
Manage grinding
Grinding or clenching puts extra force on crowns and bridges. Your dentist may recommend a night guard.
Keep up dental visits
Regular examinations let your dentist check the restoration, supporting teeth, gums and bite.
Watch for problems
See your dentist if you notice:
- Ongoing sensitivity.
- Pain when biting.
- A loose crown or bridge.
- Cracks or chips.
- Bleeding or swollen gums.
- Food getting trapped.
- A bite that feels uneven.
How long do crowns and bridges last?
Crowns and bridges can last many years, but they do not last indefinitely and there is no guaranteed lifespan. The material, the fit, the supporting teeth, your hygiene, gum health, bite forces, grinding, diet and regular care all play a part.
| Recommended Habit | Why It Matters |
| Brush twice daily | Controls plaque around teeth and restorations |
| Clean between teeth | Removes debris from hard-to-reach areas |
| Clean beneath bridge pontics | Reduces plaque build-up under the bridge |
| Avoid biting hard objects | Lowers the risk of cracks and damage |
| Address teeth grinding | Reduces excess force on restorations |
| Attend dental examinations | Allows professional monitoring |
| Report discomfort or looseness | Helps catch problems early |
Even with good care, restorations can wear out or need replacing.

Frequently Asked Questions
What is the difference between dental crowns and bridges?
Dental crowns cover and restore teeth you still have, while dental bridges replace one or more missing teeth using artificial teeth supported by neighbouring teeth or implants. They serve different purposes, and your oral health decides the right choice.
When do you need a dental crown?
You may need a dental crown when a tooth is badly decayed, cracked, weakened by a large filling or needs protection after root canal treatment. A crown restores the tooth’s strength and function. Your dentist decides whether a crown or another restoration is best.
How long do dental crowns and bridges last?
Dental crowns and bridges can last many years, but their lifespan varies with the material, the supporting teeth, your hygiene, bite forces and regular care. Check-ups help spot wear or damage early. There is no guaranteed lifespan.
Is getting a dental crown or bridge painful?
Getting a crown or bridge is not usually painful, because local anesthetic numbs the area during tooth preparation. Some temporary sensitivity or mild soreness afterward is common. Talk to your dentist about any concerns or anxiety.
Can dental bridges replace more than one missing tooth?
Yes, bridges can replace several missing teeth in suitable cases. Where the gap is, the strength of the supporting teeth or implants, your bite and your overall oral health all affect how many. Your dentist will recommend the right design.
Restoring Strength and Confidence
Crowns and bridges are well-established ways to protect damaged teeth and replace missing ones. Crowns rebuild teeth you still have, while bridges fill gaps, and the right choice reflects your oral health and goals.
