Crowns & Bridges
Dental crowns and bridges are the fixed restorations that help in reinforce the structure of a fractured/damaged tooth and replace one or more missing teeth respectively.
A Dental Crown is a single cap that is customised to fit the needy tooth. These are made of full porcelain, full metal or metal with porcelain on top. The tooth is trimmed down and reshaped into a smaller size. Any decay or loose existing fillings will be removed and restored to form the core over which the crown is cemented.
The procedure involves preparing the tooth and then an impression is taken to fabricate the crowns at the lab. It takes about 2 weeks to get the crown back, which will then be cemented in a subsequent appointment. Meanwhile a temporary crown will be placed on the day, to cover the prepared tooth.
Indications of dental crowns are:
Decayed tooth whose structure is weakened
Post root canal treatment, especially when tooth’s structure is compromised
Anchor tooth for a dental bridge
A Dental Bridge comprises two or more crowns with false teeth attached in the middle, called pontic. However, in some occasions pontics are attached to single crowns (Cantilever bridges) or wings (Maryland bridges) for retention. Bridges are made of various materials that include porcelain fused to metal or all porcelain or all zirconia.
