Dentistry Crowns and Bridges
What are the differences between dental crowns and bridges
Crowns and bridges are two of the most popular treatments performed in the dentist’s clinic. Their main goal is to restore full chewing function to a tooth or teeth. Crowns and bridges are distinct in many ways, and because bridges require crowns, we’ll start with a single crown.
What is the definition of a crown?
A crown, often known as a cap, is a dental treatment that replaces the outer layer of enamel with new material and covers the entire tooth. A crown is shaped and sized like a natural tooth, and it comes into normal contact with the opposing tooth, allowing food to be chewed properly. When it comes to function, a crown should feel similar to a natural tooth. Depending on the crown material, it can even appear to be a totally natural tooth.
Crowns are made from a variety of materials.
Crowns can be made of a variety of materials, including plastic, metals, porcelain, or a mix of these materials. As seen in the chart below, different materials serve different purposes and have different advantages and disadvantages.
Crown type Frequently used for: Advantages: Disadvantages
Plastic Temporary crowns are used while a permanent crown is being made in a dental lab. Very low-cost They are only temporary and cannot be termed a thorough restoration. Made completely of metal (typically yellow gold) Teeth with a short height towards the back of the mouth
Minimal tooth structural removal is required.
Long-term M has a high success rate.
The highest level of deterioration resistance
Appearance of metal

Where metal is visible at the gumline, it might show black shading.
Unlike actual teeth, the appearance is opaque.
Porcelain can break.
Any front tooth made entirely of porcelain
The most aesthetically attractive look
It most closely resembles a genuine tooth.
It necessitates the removal of the majority of the tooth structure.
Patients who grind their teeth can easily fracture them.
Zirconia is a material that can be used to replace any tooth in the mouth.
The appearance is similar to that of a natural tooth, however, it is slightly more opaque.
It’s effective at masking the discoloration of a tooth.
Very strong, with a very little chance of fracture
Newer material that hasn’t been subjected to long-term research
It has the potential to harm the tooth it bites.
What are the Benefits of Crowns on Teeth
When a tooth is no longer robust enough to endure normal chewing function on its own, it requires a crown. A crown may be required for a tooth to function correctly for a variety of reasons:
- Large decay – A tooth with a large cavity that has destroyed the enamel and dentin (teeth’s core structure) will be too weak to hold a filling and chew correctly. The tooth will be able to perform its function again after the cavity is removed, rebuilt, and covered with a crown.
2. Large fillings — If a large filling covers more than half of a tooth, the remaining tooth structure is too weak to resist chewing pressures for the rest of the tooth’s life. The tooth’s long-term prognosis is improved by capping it with a crown.
3. Cracks – Tooth cracks are a difficult diagnosis to make and could be the subject of a separate article. A crown is the only option to keep a limited-extension tooth fracture from getting worse (i.e., one that does not extend into the nerve inside the tooth or down the root beneath the gums). Enamel is a protective coating that coats the teeth in a thick layer. If a crack in that layer of enamel occurs, it is no longer fulfilling its job and must be removed and replaced. The crown serves as a replacement for enamel, protecting the tooth in the same way that enamel did.
4. When a tooth is treated with a root canal, the nerve and blood arteries in the hollow chamber inside the tooth are removed. This indicates that the tooth is no longer receiving food, and it is soon becoming dry and brittle. This brittleness puts the teeth at risk of fracture. A crown must be placed over any tooth that has undergone a root canal to keep it from cracking. Root canals are costly, and it would be a shame to squander one since the tooth was never protected and cracked, necessitating extraction.
What is the definition of a bridge?
A bridge is a fixed partial denture that is anchored (glued) to the teeth, substitutes some (but not all) of the teeth, and replaces missing teeth with a false tooth or teeth (denture).
When there are functioning teeth on both sides of the missing tooth, a bridge is utilized to replace one or more missing teeth.
The bridge covers the adjacent teeth, known as retainers, in the same way, that a crown covers a single tooth. The bridge attaches the crowns to a pontic (artificial tooth replacement) in the void left by a missing tooth.
A bridge would consist of three parts in the event of a single lost tooth: one for each adjacent retainer tooth and one for the pontic. Bridges can be created from the same materials that are used to make crowns.
What Are the Advantages of Having a Bridge
A bridge is a simple solution for replacing 1-2 lost teeth. It does not necessitate surgery and is usually covered by dental insurance as a covered benefit.
Your dentist will need to see you twice for a bridge. During the initial appointment, the two adjacent teeth are prepped in the same way that crowns would be. While the bridge is being created by a dental lab, you can wear a temporary bridge or merely two separate temporary crowns. The final bridge is fitted and fastened to the teeth during the second session.
A bridge cannot be cleaned as easily as individual teeth since it links numerous teeth together. You’ll need to utilize additional oral hygiene equipment to assist you to get floss underneath the bridge and cleaning it thoroughly.
To put it another way, it takes a little more effort to keep it clean and cavity-free. In certain circumstances, the neighboring teeth are unaffected, therefore healthy tooth structure must be taken to form the bridge.
What are the Bridge’s Alternatives?
One or more missing teeth are replaced by a bridge. There are two other generic tooth replacement options. One is a detachable partial denture, which is taken in and out as the name implies. It is not affixed to the teeth in any way.
A removable partial denture is held in place by a metal or plastic base that sits on neighboring teeth. A dental implant is the alternative tooth replacement option. Because it is secured in the jawbone and does not rely on or impact surrounding teeth, a dental implant is the most expensive tooth-replacement option.
