Missing or damaged teeth can significantly impact your smile, your ability to chew comfortably, and even your overall oral health. Thankfully, modern dentistry offers excellent solutions to restore your smile and confidence. Two of the most common and effective options are dental crowns and dental bridges.
While both serve to improve the function and aesthetics of your teeth, they address different issues and are suitable for different situations. Understanding the differences between them can help you make an informed decision with your dentist.
Let’s dive into the specifics of dental crowns and dental bridges to help you determine which might be the best choice for your unique needs.
What is a Dental Crown?
A dental crown is essentially a custom-made “cap” that is placed over a damaged or weakened tooth. It completely covers the visible part of the tooth, from the gum line up, restoring its shape, size, strength, and appearance.
When is a Dental Crown Recommended?
Dental crowns are a versatile solution for a variety of dental problems, including:
- Protecting a weak tooth from breaking (e.g., a tooth with a large filling)
- Restoring an already broken tooth or a tooth that has been severely worn down
- Covering and supporting a tooth with a large filling when there isn’t much tooth structure left
- Holding a dental bridge in place (in this case, the crown serves as an anchor)
- Covering misshapen or severely discolored teeth for cosmetic improvement
- Covering a dental implant
Types of Dental Crowns:
Crowns can be made from various materials, each with its own advantages:
- Porcelain or Ceramic: Popular for their natural tooth-like appearance, ideal for front teeth.
- Porcelain Fused to Metal (PFM): Offers good strength and aesthetics.
- Gold Alloys: Highly durable and biocompatible, often used for back teeth where aesthetics are less of a concern.
- Base Metal Alloys: Very strong and resistant to corrosion.
- Zirconia: Known for its exceptional strength and good aesthetics, a popular modern choice.
The choice of material will depend on the tooth’s location, your bite, and your aesthetic preferences.
What is a Dental Bridge?
A dental bridge is a prosthetic device used to bridge the gap created by one or more missing teeth. It typically consists of an artificial tooth (or teeth) called a “pontic,” which is held in place by dental crowns placed on the natural teeth on either side of the gap. These anchoring teeth are called “abutment teeth.”
When is a Dental Bridge Recommended?
Dental bridges are an excellent option when you have:
- One or more missing teeth in a row
- Healthy adjacent teeth that can support the bridge
Benefits of Dental Bridges:
- Restores your smile: Fills the unsightly gap.
- Restores your ability to chew and speak properly: Missing teeth can affect both.
- Maintains facial shape: Prevents the sunken appearance that can occur with tooth loss.
- Distributes the forces in your bite: Prevents adjacent teeth from shifting into the empty space.
- Prevents remaining teeth from drifting out of position: This helps avoid further dental problems.
Types of Dental Bridges:
- Traditional Bridges: The most common type, involving crowns on the adjacent natural teeth to support the pontic.
- Cantilever Bridges: Used when there are only healthy teeth on one side of the gap. Less common due to less support.
- Maryland Bonded Bridges (Resin-Bonded Bridges): Use metal or porcelain wings bonded to the back of adjacent teeth. Ideal for front teeth where there’s less biting force.
Dental Crowns vs. Bridges: Key Differences
| Feature | Dental Crown | Dental Bridge |
|---|---|---|
| Purpose | Repairs and strengthens a single damaged tooth | Replaces one or more missing teeth |
| Tooth Status | Applied to an existing tooth | Spans a gap where teeth are absent |
| Anchoring | Caps an individual tooth | Anchored by crowns on adjacent natural teeth |
| Number of Teeth | One tooth treated per crown | Replaces 1-3 (sometimes more) missing teeth in a row |
| Preparation | Tooth is reshaped to fit the crown | Abutment teeth are reshaped to fit crowns |

Which Option is Right for You?
The best solution for your smile depends on several factors:
- Number of missing teeth: If you have a single damaged tooth, a crown is likely. If you have missing teeth, a bridge (or implant) is considered.
- Condition of surrounding teeth: For a bridge, the adjacent teeth must be healthy and strong enough to support the prosthetic.
- Overall oral health: Your gums and remaining teeth need to be healthy.
- Budget: Costs can vary between the two procedures and material choices.
- Personal preference and long-term goals: Your lifestyle and desired outcome play a role.
For a single damaged or weakened tooth: A dental crown is generally the ideal choice to restore its strength, function, and appearance.
For one or more missing teeth with healthy adjacent teeth: A dental bridge can effectively fill the gap, restore chewing ability, and prevent shifting of remaining teeth.
A note on Dental Implants: While this post focuses on crowns and bridges, it’s important to mention dental implants as a gold standard for replacing missing teeth. Implants are surgically placed into the jawbone, providing a highly stable and long-lasting foundation for a single crown or to support a bridge, without impacting adjacent healthy teeth. We can discuss this option in more detail during your consultation.
