Damaged or missing teeth can affect how you eat, speak and feel about your smile. Dental Crowns & Bridges are restorative dental treatments that help rebuild weakened teeth, replace missing teeth and improve oral function.
A dental crown is a custom-made covering placed over an existing tooth to restore its shape, strength and appearance. A dental bridge replaces one or more missing teeth using support from neighbouring teeth or dental implants.
Both treatments can provide natural-looking results, but they address different dental problems. Choosing the right restoration depends on the condition of your teeth, gum health, bite and long-term treatment goals.
This guide explains how dental crowns and bridges work, the available treatment options, what happens during the procedure and how to care for your restorations.
What Are Dental Crowns Used For?
Dental crowns are used to restore teeth that are weakened, cracked, heavily filled or significantly damaged by decay.
A crown, sometimes called a dental cap, covers the visible portion of a prepared tooth above the gumline. It helps protect the remaining tooth structure while restoring its appearance and chewing function.
According to the Canadian Dental Association’s guidance on dental crowns, crowns are commonly recommended for damaged teeth, following root canal treatment or when a tooth needs additional support.
Protecting Cracked or Weakened Teeth
A tooth with a substantial crack or fracture may need more protection than a standard dental filling can provide.
A crown covers the remaining tooth structure and helps distribute chewing forces across the tooth.
However, not every cracked tooth can be saved with a crown. Deep fractures extending into the root may require other treatment.
A dentist must examine the tooth before recommending a restoration.
Restoring Teeth With Large Fillings
Teeth that have undergone repeated restorative treatment may have limited natural structure remaining.
When a filling becomes too large, the surrounding tooth can become more vulnerable to fracture.
A crown may provide greater coverage and support than replacing the existing filling.
Protecting Teeth After Root Canal Treatment
Root canal treatment removes damaged or infected pulp from inside a tooth.
Although the procedure can preserve the natural tooth, additional restoration may be needed to protect it.
Back teeth often require crowns after root canal therapy because they experience considerable pressure during chewing.
Sky Dental Centre provides root canal therapy in Thunder Bay and can assess whether a crown is appropriate after treatment.
Improving Tooth Shape and Appearance
Dental crowns can also improve the appearance of teeth that are severely worn, misshapen or discoloured.
Tooth-coloured materials can be selected to blend with surrounding teeth.
However, when a tooth is otherwise healthy, a less invasive treatment may be suitable.
A dentist can compare crowns with alternatives such as bonding or veneers before recommending treatment.
How Dental Bridges Replace Missing Teeth
Dental bridges replace missing teeth by holding one or more artificial teeth in the space between natural teeth or dental implants.
A conventional bridge usually consists of two crowns placed on neighbouring teeth, with an artificial tooth called a pontic positioned between them.
Unlike removable dentures, fixed bridges remain attached during normal eating, speaking and cleaning.
The Canadian Dental Association explains how dental bridges work, including the use of natural teeth or implants to support the replacement teeth.
Restoring Chewing Function
Missing teeth can make it difficult to chew certain foods comfortably.
A properly designed bridge helps replace the missing biting surfaces and distribute chewing forces.
The result depends on the number of missing teeth, the condition of supporting teeth and the overall bite.
Maintaining Tooth Position
When a tooth is missing, neighbouring teeth may gradually shift towards the empty space.
Teeth in the opposite jaw may also move into the gap.
A dental bridge can help maintain spacing by replacing the missing tooth and supporting a more stable bite.
Improving Smile Appearance
A visible gap can affect how your smile looks and, in some cases, how certain sounds are pronounced.
Dental bridges are designed to resemble natural teeth in shape, size and colour.
Modern materials allow dentists to select restorations that complement the surrounding teeth.
Who Is a Suitable Candidate for a Dental Bridge?
A dental bridge may be suitable for patients who:
- Have one or more missing teeth
- Have healthy supporting teeth or suitable dental implants
- Prefer a fixed replacement rather than a removable denture
- Have healthy gums and sufficient support for the planned restoration
- Can maintain proper cleaning around and beneath the bridge
A dentist will also assess the size of the gap, existing restorations and bite forces before recommending treatment.
Types of Dental Crowns and Bridges
Dental crowns and bridges are available in different materials and designs. Each option offers advantages depending on tooth location, appearance, durability and available support.
Common Types of Dental Crowns
| Crown Material | Main Features | Common Considerations |
| Zirconia | Strong, tooth-coloured ceramic | Often suitable for back teeth and areas with higher chewing forces |
| All-ceramic | Natural-looking appearance and light transmission | Commonly considered for visible front teeth |
| Porcelain-fused-to-metal | Metal framework covered with tooth-coloured porcelain | Combines strength with appearance, although metal may become visible near the gumline |
| Metal | Highly durable and resistant to wear | More noticeable appearance, often used for back teeth |
Sky Dental Centre discusses zirconia, all-ceramic and porcelain-fused-to-metal restorations as part of its dental crowns and bridges in Thunder Bay treatment options.
The best material depends on the tooth’s location, chewing forces, available space and cosmetic requirements.
Common Dental Bridge Options
Different bridge designs provide support in different ways.
Traditional Dental Bridges
Traditional bridges use crowns placed on natural teeth on both sides of a gap.
They are commonly used when neighbouring teeth can provide suitable support.
However, the supporting teeth must be prepared to accommodate the crowns.
Cantilever Bridges
A cantilever bridge is supported by one or more teeth on only one side of the missing tooth.
This design may be appropriate in selected situations, but it is not suitable for every location because of the forces placed on supporting teeth.
Maryland or Resin-Bonded Bridges
Maryland bridges use bonded wings, often made from metal or ceramic, attached to the back surfaces of neighbouring teeth.
They are often considered for replacing certain front teeth.
This approach may require less removal of natural tooth structure than a conventional bridge.
Implant-Supported Bridges
Implant-supported bridges are anchored to dental implants rather than relying entirely on neighbouring natural teeth.
They may be considered when several adjacent teeth are missing or when natural teeth cannot provide suitable support.
Implant treatment requires surgical placement and a healing period before the final restoration can be fitted.
Not every bridge design is suitable for every patient. Your dentist can explain which options are appropriate for your oral health and treatment goals.
Dental Bridges vs Dental Implants
A bridge and a dental implant are both possible replacement options for missing teeth, but they differ in how they are supported.
| Factor | Traditional Dental Bridge | Dental Implant |
| Support | Adjacent natural teeth | Implant placed in the jawbone |
| Tooth preparation | Usually requires preparation of supporting teeth | Usually does not require preparation of neighbouring teeth |
| Surgical procedure | Generally not required | Required for implant placement |
| Treatment time | Often completed over a shorter period | May involve several months of healing |
| Cleaning | Requires cleaning beneath the replacement tooth | Requires careful cleaning around the implant restoration |
| Suitability | Depends on supporting teeth and bite | Depends on bone health, gum health and other clinical factors |
Dental implants replace missing tooth roots, while conventional bridges use existing teeth for support.
The Canadian Dental Association’s information on dental implants explains how implants support crowns and bridges and outlines factors affecting treatment suitability.
Sky Dental Centre also provides dental implant treatment for patients considering fixed tooth replacement.

What Happens During Crown and Bridge Treatment?
The dental crown procedure and bridge treatment usually involve an examination, tooth preparation, impressions and placement of a custom-made restoration.
Traditional crown and bridge treatment often requires two appointments, although additional visits may be necessary when preliminary dental work is needed.
Some suitable crown cases may also be completed using same-day dental technology.
Step 1: Dental Examination and Treatment Planning
Your dentist examines the affected teeth, surrounding gums and bite.
Dental X-rays may be taken to assess the roots, supporting bone and condition of neighbouring teeth.
The examination helps determine whether a crown, bridge or another treatment is appropriate.
Your dentist will also discuss material choices, expected treatment stages and costs before proceeding.
Step 2: Preparing the Teeth
For a dental crown, the dentist removes a controlled amount of tooth structure to create space for the restoration.
Any decay or damaged filling material is addressed during preparation.
For a traditional bridge, the supporting teeth on either side of the gap are prepared for crowns.
Local anaesthesia is normally used to keep the area comfortable.
Tooth preparation is irreversible, so your dentist should explain why the recommended approach is appropriate.
Step 3: Taking Dental Impressions
After preparation, impressions or digital scans are taken to record the shape of the teeth and surrounding structures.
These measurements help create a restoration that fits properly and works with your bite.
The crown or bridge is designed to match the required tooth shape and, where possible, the colour of neighbouring teeth.
Step 4: Placing a Temporary Restoration
For laboratory-made crowns and bridges, a temporary restoration may be placed while the permanent one is being prepared.
A temporary crown or bridge protects the prepared teeth and helps maintain appearance and function.
During this period, patients are generally advised to avoid hard or sticky foods that could loosen the temporary restoration.
Step 5: Fitting the Permanent Crown or Bridge
Once the permanent restoration is ready, your dentist checks its fit, colour and alignment.
Adjustments may be made to improve comfort and bite contact.
The restoration is then cemented or otherwise secured according to its design.
You will receive instructions on cleaning and protecting the restored area.
Are Same-Day Dental Crowns Available?
Some dental clinics use digital scanning and computer-assisted manufacturing to produce selected crowns during a single visit.
Sky Dental Centre lists same-day crowns among its restorative services.
However, not every tooth or restoration is suitable for same-day treatment. Bridges and more complex cases may still require laboratory fabrication and multiple appointments.
Your dentist can explain which treatment process applies to your situation.
What Affects the Cost of Crown and Bridge Treatment?
The cost varies according to the type of restoration, material and complexity of treatment.
Factors may include:
- The number of teeth being restored or replaced
- The crown or bridge material
- Whether preliminary treatment is needed
- The condition of supporting teeth
- Laboratory or digital manufacturing requirements
- The number of appointments and additional procedures
An individual examination is needed to provide an accurate treatment estimate.
The clinic’s Dental Services Thunder Bay overview includes restorative options that patients may discuss when comparing treatment approaches.
How to Maintain Your Dental Restorations
Dental crowns and bridges require daily cleaning and regular dental examinations to maintain their appearance and function.
Although the restoration materials cannot develop cavities, the natural teeth supporting them can still experience decay and gum disease.
Brush Twice Daily
Brush your teeth at least twice daily using a soft-bristled toothbrush and fluoride toothpaste.
Pay attention to the gumline and the edges where crowns meet natural teeth.
Plaque can accumulate around these areas if they are not cleaned properly.
The Government of Canada’s oral health recommendations advise brushing for approximately two minutes twice daily and cleaning between teeth every day.
Clean Under Dental Bridges
A conventional dental bridge has an artificial tooth that sits above the gum, making ordinary flossing between connected bridge units difficult.
Your dentist may recommend:
- Floss threaders to guide dental floss beneath the bridge
- Interdental brushes for suitable spaces
- Water flossers as an additional cleaning aid
- Specialised floss designed for fixed dental restorations
Cleaning beneath the bridge helps remove trapped food and plaque.
Avoid Biting Hard Objects
Crowns and bridges are designed for normal chewing, but excessive force can damage restoration materials.
Avoid using your teeth to open packaging or bite hard objects such as ice and pens.
If you grind or clench your teeth, ask your dentist whether a protective nightguard may be appropriate.
Attend Regular Dental Checkups
Regular appointments allow your dentist to examine the condition of your crowns, bridges and supporting teeth.
Your dental team can look for:
- Loose or damaged restorations
- Tooth decay around crown margins
- Gum inflammation near bridge supports
- Changes in bite alignment
- Excessive wear or fractures
Early assessment may allow some problems to be managed before further damage occurs.
Recognise Signs That a Restoration Needs Attention
Contact your dentist if you notice:
- Persistent pain or sensitivity around a crown
- A loose or moving bridge
- A chipped or fractured restoration
- Bleeding or swollen gums around supporting teeth
- Food repeatedly becoming trapped in the same area
- A change in how your teeth fit together
Do not attempt to repair a loose crown or bridge using household adhesives.
Professional assessment can determine whether adjustment, repair or replacement is required.
Frequently Asked Questions About Dental Crowns and Bridges
How long do crowns and bridges last?
Dental crowns and bridges can last 10 years or longer with proper care, although individual results vary. The Canadian Dental Association notes that well-maintained crowns and bridges may provide many years of service. Their lifespan depends on the restoration material, oral hygiene, bite forces, teeth grinding and the condition of supporting teeth.
Is the treatment painful?
Crown and bridge treatment is generally performed using local anaesthesia, which numbs the treatment area. Patients may feel pressure or vibration during tooth preparation, but sharp pain should not be expected. Mild sensitivity or gum tenderness may occur afterwards. Contact your dentist if discomfort is severe or persistent.
Can bridges replace several missing teeth?
Yes. Dental bridges can replace multiple adjacent missing teeth when there is sufficient support from neighbouring teeth or dental implants. The number of teeth that can be replaced depends on the size of the gap, the supporting structures and the forces placed on the restoration. A dentist must assess whether the proposed bridge is suitable.
How are bridges different from implants?
A traditional dental bridge replaces missing teeth by attaching to neighbouring natural teeth, while a dental implant replaces a missing tooth root with a post placed in the jawbone. Implants generally do not require preparation of adjacent teeth but involve surgery and healing time. The better option depends on oral health, available bone, treatment preferences and clinical suitability.
Do crowns and bridges look natural?
Yes. Modern crowns and bridges can be designed to closely resemble natural teeth. Tooth-coloured materials such as zirconia and porcelain allow dentists to match the shape, size and shade of surrounding teeth. The final appearance depends on the material selected, the position of the restoration and individual dental characteristics.
Restore Your Smile With Dental Crowns & Bridges
Dental Crowns & Bridges provide established options for restoring damaged teeth and replacing missing teeth.
A crown can help protect a weakened natural tooth, while a bridge fills spaces left by missing teeth and supports chewing function and smile appearance.
The most suitable restoration depends on your dental health, the condition of neighbouring teeth and your long-term goals. A professional examination can help determine whether a crown, bridge, implant or another treatment is appropriate.
