Dental Crowns and Bridges: Your Complete Guide to Tooth Restoration

Missing or damaged teeth affect more than just your smile—they impact your ability to eat, speak, and feel confident in social situations. Dental crowns and bridges are time-tested restorative solutions that can repair damaged teeth and replace missing ones, restoring both function and aesthetics. Understanding these treatment options, their benefits, and what to expect during the process can help you make informed decisions about your dental health.

Understanding Dental Crowns

What Is a Dental Crown?

A dental crown is a custom-made cap that covers a damaged or weakened tooth completely, restoring its shape, size, strength, and appearance. Think of it as a protective helmet for your tooth that:

• Encases the entire visible portion of the tooth above the gum line
• Restores function for chewing and speaking
• Protects weakened tooth structure from further damage
• Improves aesthetic appearance
• Can last 10-15 years or longer with proper care

When Are Crowns Necessary?

Protecting Weak or Damaged Teeth:

• Large cavities where fillings won’t provide adequate support
• Teeth weakened by extensive decay
• Cracked or fractured teeth
• Teeth worn down from grinding (bruxism)
• Structurally compromised teeth

After Dental Procedures:

• Following root canal treatment to protect treated tooth
• Covering dental implants
• Anchoring dental bridges
• Completing cosmetic improvements

Cosmetic Improvements:

• Severely discolored teeth resistant to whitening
• Misshapen or irregular teeth
• Gaps or spacing issues
• Improving overall smile aesthetics

Types of Dental Crowns

Porcelain or Ceramic Crowns:

• Best for front teeth due to natural appearance
• Excellent color matching with natural teeth
• Biocompatible and gentle on surrounding tissues
• May be less durable than metal options
• Ideal for patients with metal allergies

Porcelain-Fused-to-Metal (PFM) Crowns:

• Combine strength of metal with aesthetics of porcelain
• Durable for back teeth that withstand heavy chewing
• Good color match, though metal may show at gum line
• Proven track record of longevity
• Balanced option for strength and appearance

Gold or Metal Alloy Crowns:

• Extremely strong and durable
• Withstand biting and chewing forces well
• Require less tooth removal than other types
• Very long-lasting (20+ years possible)
• Most noticeable appearance (typically for back teeth)

Zirconia Crowns:

• Modern material combining strength and aesthetics
• Highly durable and resistant to fracture
• Excellent biocompatibility
• Natural tooth-like translucency
• Increasingly popular choice in modern dentistry

All-Resin Crowns:

• Most affordable crown option
• Good temporary or short-term solution
• More prone to wear and fracture
• May need replacement sooner
• Less common for permanent restorations

The Crown Procedure

First Appointment – Preparation (60-90 minutes):

1. Examination and Planning: Dentist examines tooth, takes X-rays, discusses options
2. Anesthesia: Local anesthetic numbs the area for comfort
3. Tooth Preparation: Reshaping tooth to accommodate crown (removing damaged portions)
4. Impressions: Digital scan or traditional impressions of prepared tooth
5. Temporary Crown: Protects tooth while permanent crown is fabricated
6. Shade Selection: Choosing color to match natural teeth

Between Appointments (1-2 weeks):

• Dental laboratory fabricates custom crown
• Temporary crown protects prepared tooth
• Normal activities with minor dietary restrictions

Second Appointment – Placement (30-60 minutes):

1. Temporary Removal: Taking off temporary crown carefully
2. Fit Check: Ensuring proper fit, bite, and aesthetics
3. Adjustments: Fine-tuning as needed
4. Cementation: Permanent bonding of crown to tooth
5. Final Check: Verifying comfort and bite alignment

Same-Day Crowns (CEREC Technology):

• Available at some advanced dental clinics in Nairobi
• Computer-aided design and manufacturing
• Custom crown created in single appointment
• Completed in 2-3 hours
• No temporary crown or second visit needed

Understanding Dental Bridges

What Is a Dental Bridge?

A dental bridge is a fixed restoration that replaces one or more missing teeth by “bridging” the gap between existing teeth. The structure consists of:

• Pontics: Artificial teeth that fill the gap
• Abutments: Natural teeth or implants on either side that support the bridge
• Crowns: Caps placed on abutment teeth for support

Bridges restore your smile, maintain face shape, prevent remaining teeth from shifting, restore chewing and speaking ability, and distribute bite forces properly.

Types of Dental Bridges

Traditional Fixed Bridge:

• Most common type of bridge
• Pontic supported by crowns on adjacent teeth
• Requires reshaping neighboring teeth
• Very stable and strong
• Suitable for back and front teeth

Cantilever Bridge:

• Supported by crown on only one adjacent tooth
• Used when teeth present on one side only
• Less common due to increased stress
• Typically used for front teeth
• Not ideal for molars with heavy chewing forces

Maryland (Resin-Bonded) Bridge:

• Metal or porcelain framework bonded to back of adjacent teeth
• Requires minimal tooth preparation
• More conservative approach
• Best for front teeth with less biting force
• May not be as durable as traditional bridges

Implant-Supported Bridge:

• Supported by dental implants rather than natural teeth
• Doesn’t require altering adjacent healthy teeth
• Most stable and long-lasting option
• Requires sufficient bone density
• Higher initial cost but excellent long-term value

When Are Bridges Recommended?

Missing Teeth:

• One or more consecutive missing teeth
• Adequate adjacent teeth for support
• Good overall oral health
• Sufficient bone structure
• Desire for fixed (non-removable) solution

Advantages Over Removable Dentures:

• Permanently fixed in place
• More natural feel and function
• No removal for cleaning
• Better chewing efficiency
• More stable and comfortable

The Bridge Procedure

First Appointment – Preparation (90-120 minutes):

1. Comprehensive Examination: Assessment of teeth, gums, and bone
2. Treatment Planning: Discussing bridge type and materials
3. Tooth Preparation: Reshaping abutment teeth to receive crowns
4. Impressions: Creating molds for custom bridge fabrication
5. Temporary Bridge: Protecting prepared teeth and maintaining aesthetics
6. Color Matching: Selecting shade to blend with natural teeth

Laboratory Fabrication (2-3 weeks):

• Custom bridge created by dental technicians
• Precise fit and natural appearance
• Quality materials for longevity
• Multiple stages of fabrication and quality checks

Second Appointment – Placement (60-90 minutes):

1. Temporary Removal: Carefully removing temporary bridge
2. Fit Verification: Checking bridge fit, bite, and appearance
3. Adjustments: Making necessary modifications
4. Cementation: Permanently bonding bridge in place
5. Final Evaluation: Ensuring comfort, function, and aesthetics
6. Care Instructions: Guidance on maintaining bridge

• Wear nightguard if you grind teeth
• Don’t bite fingernails or chew pens

Regular Dental Checkups

Professional Monitoring:

• Biannual cleanings and examinations
• Early detection of problems
• Professional cleaning around crowns and bridges
• X-rays to monitor underlying tooth structure
• Adjustments if needed
• Assessment of restoration condition

Potential Problems and Solutions

Common Issues with Crowns

Sensitivity:

• Normal for first few days after placement
