Q-What is a "tooth crown"?
A-There are a variety of factors that may contribute to the deterioration of teeth over the course of time. Age, tooth decay, defective fillings, improper bites and chewing patterns all play a role in the eventual wearing down and cracking of teeth. Dental crowns can reverse the effects of time by covering the entire visible surface of a tooth with enamel and porcelain to both strengthen the tooth and increase its durability. Crowns also improve the appearance of worn down and damaged teeth. Your dentist can tell you which problem areas in your mouth might be helped by the placement of a crown.
Crowns come in two basic types: porcelain fused to metal and full ceramic crowns. Porcelain fused to metal crowns are an option in cases where extra resistance is needed for any given reason. Full ceramic crowns are very popular as they can be made to closely resemble natural tooth color and transparency. Advancements in composite resin materials and bonding technology have also limited the need for metallic crown anchors that hold the crown in place.
Dental Bridges
Q-What is the dental bridges procedure?
A-A dental bridge is basically a false tooth (also known as a pontic) which is placed in the space left by a missing tooth. Porcelain crowns on either side of the tooth are bonded with resin to the pontic in what is known as a fixed bridge. This procedure can be used to replace one or more missing teeth.
Bridges reduce the risk of gum disease and help correct some bite issues. They can last for a long time.
Q-What are the pros and cons of dental bridges?
A-Bridges appear natural and blend in well with your existing teeth. They can also usually be set in only two office visits to your dentist. With a regimen of good oral hygiene they can last as many as ten years or more.
The biggest risk in having a dental bridge is the possibility of gum disease if a serious commitment to oral hygiene is not made. Another minor side effect is a mild sensitivity to extreme temperatures during the laboratory process, while you are wearing your temporal crowns.
