Crowns are tooth shaped "caps" that are placed over the front or back teeth and they cover it to restore its shape and size, strength, and/or to improve its appearance. The crowns fully encase the entire visible portion of a tooth that lies at and above the gum line.
A missing tooth can detract from even the most beautiful smile. A Bridge, also known as a fixed partial denture, is a Dental restoration used to replace a missing tooth by joining permanently to adjacent teeth. A Dental Bridge can fill the gap created by one or more missing teeth. A Bridge uses two crowns on the teeth on either side of the gap and false tooth/teeth (Pontic) in between. These false teeth called Pontics can be made from Alloys, Porcelain, Gold or a combination of these materials. Dental Bridges can be supported by natural teeth or by implants.
There are different types of Bridges, depending on how they are fabricated and the way they anchor to the adjacent teeth.
Fitting and placement of Dental Bridges is a two-visit process. During the first visit, the abutment teeth or the teeth on either side of the missing tooth/teeth are prepared. The preparation may involve re-contouring these teeth to allow room for a crown to be placed over them. Then impressions of your teeth are made which serve as the model from which the Dental lab will make your Bridge. The temporary Bridge can be made for you to wear until you get the permanent one is fabricated. During the second visit, the temporary Bridge is removed and permanent Bridge is cemented after a bisque trial.
Missing teeth need to be replaced at every cost as one missing lower molar ultimately causes damage to 5 teeth. All our teeth balance on each other. Likewise upper teeth reply on lower teeth for something to chew against. When a back tooth is lost, there may not appear to be any immediate problems with the rest of your teeth. However, over a period of time, problems develop that can lead to the loss of several other teeth. The reason is, when the lower back molar tooth is lost, the teeth next to it can tip over into the space left by the missing tooth. In addition, it is very common for the upper opposing tooth to overgrow and once this happens there is no way of pushing that tooth back into its correct position and it usually needs to be removed. In other words, by losing one back molar tooth and not replacing it, a domino effect usually begins, causing the ultimate loss of several other back teeth. Over time, other problems such as increased spacing between front teeth, abnormal bite characteristics, increased incidence of gum disease, increased decay, increased stresses on remaining teeth,
Another type of Dental Bridge, called a cantilever Bridge, is used to replace a missing tooth in an area of the mouth that receives less physical stress. This type of Dental Bridge is used when just one side of the empty space caused by an absent tooth has remaining healthy teeth. With a cantilever Bridge, the false tooth is anchored to one or more natural teeth on one side only.
