What is a dental crown?
A dental crown completely encases a damaged tooth with a custom design, custom fit cap that fits perfectly over a damaged tooth. The crown thereby restores full functionality to a tooth.
What is a dental bridge?
A bridge, also known as a fixed prosthesis, is made to replace one or more missing teeth. Unlike dentures it cannot be removed daily and cleaned. Bridges can be supported in any of three ways:
By natural teeth
By a combination of teeth and implants
Why are crowns placed?
Crowns may be placed for several reasons. Usually the tooth has been broken or severely damaged by decay. As a result, a filling can’t replace enough of the tooth or make the tooth strong enough. A crown may hold together parts of a cracked tooth. It also can be used to hold a bridge in place. Crowns can be used to improve appearance as well. They may be placed to cover misshapen or badly discolored teeth. They are also used to cover a dental implant. It can also be used to protect a weak tooth from fracturing.
What is the material used for crowns and bridges?
There are 3 primary materials- all ceramic (porcelain), porcelain fused to metal, or gold.
What are side effects of dental bridges?
There is a risk of gum infection and inflammation. There can be allergies to the materials being used. It also requires two healthy teeth adjacent the missing tooth to be shaped to accept the crowns of the new dental bridge.
What are the alternatives to dental bridge?
Dental implants are used for replacing missing teeth today. While dental implants are more costly their benefits are much greater.
What are the different types of bridges?
There are many types of bridges:
A cantilever bridge is held in the mouth by one or more crowns on only one side of the space where a tooth is missing.
A Maryland bonded bridge consists of a metal framework with “wings” on each side. The wings are bonded to the back of your existing teeth. The false teeth are also bonded to the framework. This type of bridge is also called a resin-bonded bridge or an acid-etched bridge.
Bonded bridges usually are not as expensive as traditional bridges. That’s because the adjacent teeth need less preparation and do not get crowns. However, these bridges are only as strong as the bonding material. Resin-bonded bridges tend not to stay cemented in place as well as other kinds in parts of the mouth where there is a lot of biting force. They also may not be the best choice if the wings will have to be small to avoid getting in the way of the bite or the gums.
