When it comes to dental restoration, two of the most common options are dental bridges and dental crowns. Both procedures are used to restore damaged, decayed, or missing teeth, but they serve different purposes. A crown typically covers a single damaged tooth, while a bridge is used to fill in gaps caused by one or more missing teeth. Knowing the difference between these two options can help you make an informed decision about which procedure is right for your dental needs.
In this comprehensive guide, we’ll dive deep into the bridge vs crown debate. We’ll explore the benefits, drawbacks, costs, and various factors that can influence your choice. Whether you’re trying to restore a single tooth or replace multiple missing ones, this article will provide valuable insight into the decision-making process.
What is a Dental Bridge?
A dental bridge is a fixed dental appliance designed to fill the gap created by one or more missing teeth. It is made up of two crowns that fit over the adjacent natural teeth or dental implants, and one or more artificial teeth (pontics) placed in between. These artificial teeth are typically made of porcelain, ceramic, or a combination of both, and they mimic the appearance of natural teeth.
Structure of a Dental Bridge
-
Pontics: The artificial teeth that replace the missing teeth.
-
Abutment teeth: The natural teeth or implants that support the bridge.
-
Types of Bridges: There are several types of bridges, including traditional, cantilever, Maryland, and implant-supported bridges. The choice of type depends on the location of the missing teeth and the health of surrounding teeth.
Why Choose a Bridge?
A dental bridge is an ideal option for patients who are missing one or more teeth but still have healthy teeth on either side of the gap. A bridge restores the function of the missing teeth, improves the aesthetics of your smile, and helps prevent remaining teeth from shifting out of alignment.
Procedure for Getting a Bridge
The process for getting a dental bridge involves at least two dental visits. During the first visit, your dentist will prepare the abutment teeth by removing a small portion of enamel to make room for the crowns. An impression of your teeth will be made to ensure the bridge fits properly. A temporary bridge will be placed until the permanent one is ready. In the second visit, the permanent bridge is placed and adjusted for a perfect fit.
What is a Dental Crown?
A dental crown is a tooth-shaped cap that is placed over a damaged or decayed tooth to restore its size, shape, strength, and appearance. Crowns can be made from a variety of materials, including porcelain, ceramic, resin, or metal. They are custom-designed to match the natural color and texture of the surrounding teeth, ensuring that the crown blends seamlessly into your smile.
Purpose of a Dental Crown
-
Protection: Crowns protect a weakened or damaged tooth from further decay or damage.
-
Restoration: Crowns are used to restore the appearance and function of a tooth that has been chipped, cracked, or decayed.
-
Cosmetic Enhancement: Crowns are often used for cosmetic purposes, such as improving the shape or color of a tooth.
When Should You Get a Crown?
A dental crown may be necessary if you have a tooth that is severely damaged, cracked, or decayed. Crowns are also used for teeth that have undergone root canal therapy, as the tooth may become brittle and require protection.
Procedure for Getting a Crown
Like with a dental bridge, getting a crown typically involves two visits. During the first visit, the dentist will prepare the tooth by removing a portion of the enamel to make room for the crown. An impression of the tooth is taken, and a temporary crown is placed. The permanent crown is then placed during the second visit once it has been custom-made.
Bridge vs Crown: Key Differences
Now that we’ve explored what a dental bridge and a dental crown are, let’s dive into the key differences between the two options. Understanding these differences will help you determine which procedure is right for your unique dental needs.
Cost
Dental Bridges: Bridges tend to be more expensive than crowns because they require more materials and labor to fabricate. The cost also depends on the type of bridge you choose and whether your dentist uses high-end materials.
Dental Crowns: Crowns are generally more affordable than bridges because they only involve restoring a single tooth. However, the cost can still vary depending on the material and complexity of the crown.
Functionality
Dental Bridges: A bridge is typically used to replace one or more missing teeth. The procedure restores your ability to chew and speak properly and improves the overall function of your mouth.
Dental Crowns: Crowns are used to restore a single tooth that is damaged, decayed, or weakened. They are ideal for preserving the structure of a natural tooth and protecting it from further damage.
Procedure
Dental Bridges: The procedure for getting a bridge requires reshaping the adjacent teeth to serve as anchors for the bridge. This can be a more invasive procedure than a crown, as it involves altering the surrounding teeth.
Dental Crowns: Getting a crown usually involves less preparation. The dentist simply needs to trim down the damaged tooth to fit the crown.
Aesthetics
Dental Bridges: Bridges are often a better option for people who are missing multiple teeth in a row. The restoration looks more natural, as it replaces multiple teeth with one continuous appliance.
Dental Crowns: Crowns are ideal for restoring a single tooth. If the crown is made of porcelain or ceramic, it can blend well with your natural teeth and enhance the overall aesthetics of your smile.
Which One is Right for You?
Choosing between a dental bridge and a dental crown depends on several factors. Here are some key considerations to help you decide which option is best for your dental needs:
Missing Teeth
If you’re missing one or more teeth, a dental bridge is likely the better choice. Bridges are specifically designed to replace missing teeth, restoring both function and appearance. On the other hand, a crown is only suitable for restoring a single, damaged tooth.
Damaged Teeth
If you have a single tooth that is severely decayed or cracked, a dental crown is usually the best option. A crown will protect the tooth and restore its function without affecting the surrounding teeth.
Cost Considerations
For patients on a budget, a crown may be the more affordable option, especially if only one tooth needs restoration. However, if you’re missing multiple teeth, a bridge may be the better investment in terms of both functionality and aesthetics.
Long-Term Durability
Both crowns and bridges can last many years with proper care, but crowns are often more durable in the long run since they focus on protecting a single tooth. Bridges can last for 10-15 years, but they may require replacement sooner than crowns, especially if the surrounding teeth are not well-maintained.
Pros and Cons of Dental Bridges vs Crowns
When considering whether to get a dental bridge or crown, it’s important to weigh the pros and cons of each option. Let’s break down the advantages and disadvantages of both procedures.
Dental Bridges
Pros:
- Restores multiple missing teeth in one procedure.
- Prevents remaining teeth from shifting out of place.
- Improves both function and appearance.
- Long-lasting and durable.
Cons:
- More expensive than crowns.
- Requires reshaping of adjacent teeth.
- Can put stress on the supporting teeth, which may lead to issues later.
Dental Crowns
Pros:
- Protects and strengthens a damaged or weakened tooth.
- Provides a natural-looking restoration.
- Requires minimal preparation compared to bridges.
- Long-lasting and durable when properly maintained.
Cons:
- Only suitable for restoring a single tooth.
- Requires trimming of the natural tooth.
- Can be expensive depending on the material used.

Conclusion
Ultimately, whether you choose a dental bridge or crown depends on your individual needs. If you’re missing multiple teeth in a row, a bridge may be the best option to restore your smile and chewing function. However, if you only have a single damaged or decayed tooth, a crown is likely the more affordable and less invasive choice.
