Crowns and bridges are two of the most common dental restorations used to restore damaged or missing teeth. They help restore the function, appearance, and strength of teeth that have been compromised due to decay, injury, or wear.

What Are Crowns?
A dental crown is a cap that covers a damaged tooth, restoring its size, shape, and strength. Crowns are often used when a tooth is weakened by decay or has undergone a root canal. They can also be used to cover a dental implant or to improve the appearance of a tooth.

What Are Bridges?
A dental bridge is a restoration used to replace one or more missing teeth. The bridge consists of one or more artificial teeth (pontics) that are anchored in place by dental crowns on the adjacent natural teeth. The bridge restores both the appearance and function of the missing teeth.

How Do Crowns Work?

• The dentist prepares the affected tooth by removing any decay or damaged structure.
• Impressions are taken to ensure the crown fits perfectly.
• A temporary crown is placed while the permanent one is being fabricated.
• Once the crown is ready, it is permanently cemented onto the tooth.

How Do Bridges Work?

• The adjacent teeth to the gap are prepared by removing a portion of their enamel to accommodate crowns.
• Impressions are taken to create a custom-made bridge.
• A temporary bridge is placed while the permanent one is being made.
• The bridge is cemented into place once it is ready, filling the gap and restoring the appearance and function of the missing teeth.

Who Is a Candidate for Crowns and Bridges?

• People with severely damaged or decayed teeth.
• Individuals who are missing teeth and have adjacent healthy teeth to support a bridge.
• People looking to improve the aesthetics or strength of their smile.
• Those who have undergone root canal treatment and need to cover the treated tooth.

What Are the Advantages of Crowns?

• Restores the strength and function of a damaged tooth.
• Improves the appearance of the tooth by covering discoloration or irregular shape.
• Provides protection for a weak tooth that could otherwise break or fracture.
• Can be placed on top of a dental implant to replace a missing tooth.

What Are the Advantages of Bridges?

• Bridges are a permanent solution to replace missing teeth, preventing shifting of surrounding teeth.
• They help restore the ability to chew, speak, and smile with confidence.
• Bridges maintain facial shape by preventing bone loss due to missing teeth.
• They are a more affordable alternative to dental implants when replacing one or more missing teeth.

What Materials Are Used for Crowns and Bridges?

• Porcelain: Offers a natural appearance, blending seamlessly with the surrounding teeth.
• Ceramic: Similar to porcelain but may be more durable.
• Metal: Often made of gold or other alloys, providing strength and longevity, though less aesthetic.
• Porcelain-Fused-to-Metal (PFM): Combines the strength of metal with the appearance of porcelain, commonly used for both crowns and bridges.

What Are the Different Types of Crowns?

• All-Ceramic Crowns: Best for front teeth due to their natural appearance.
• Porcelain-Fused-to-Metal Crowns: A balance between aesthetics and strength, often used for back teeth.
• Metal Crowns: Provide excellent durability and are often used for molars or teeth that are out of sight.
• Zirconia Crowns: Highly durable and natural-looking, ideal for both front and back teeth.

What Are the Different Types of Bridges?

• Traditional Bridge: The most common type, supported by crowns on both sides of the gap.
• Cantilever Bridge: Used when there are healthy teeth on only one side of the gap.
• Maryland Bridge: A metal or porcelain framework attached to the back of adjacent teeth, often used for front teeth.
• Implant-Supported Bridge: Used when multiple teeth are missing and implants are used to support the bridge.

How Long Do Crowns and Bridges Last?
Crowns and bridges typically last between 10 to 15 years with proper care. Good oral hygiene, regular dental visits, and avoiding habits like grinding or chewing hard objects can help extend their lifespan.

Are There Any Risks or Complications with Crowns and Bridges?

• Sensitivity: Some people may experience sensitivity to hot or cold foods after the procedure.
• Gum Recession: Over time, the gum line may recede, revealing the edges of the crown or bridge.
• Damage: Crowns or bridges can become damaged or dislodged if not cared for properly, especially in cases of trauma or biting hard foods.
• Wear and Tear: The restoration may need to be replaced or adjusted after several years of use.

How Do I Care for Crowns and Bridges?

• Brush your teeth at least twice a day, using a soft-bristled toothbrush and non-abrasive toothpaste.
• Floss around crowns and bridges daily to remove plaque and food particles.
• Avoid sticky or hard foods that can damage the restoration.
• Visit your dentist regularly for check-ups and cleanings.
