A dental bridge, which is also known as a fixed removable denture, is a variety of crown that is used to replace one or two missing tooth. A bridge is made up of 2 crowns for the teeth on each side of the gap and false tooth/teeth (pontic) in between the crowns. A bridge can either be supported by natural teeth, implants or a mixture of both. There are 3 main kinds of dental bridges.
Conventional Bridges. A conventional bridge has a crown for each side of the gap and is formed with a pontic in the middle. This is the most preferred kind of dental bridges and they can either be made from ceramics or porcelain that's fused to a metal.
Maryland Bonded Bridges. The Maryland Bonded Bridges, often referred to as the resin bonded bridges, are commonly chosen when the teeth on each side of the opening are healthy and robust with no enormous fillings or when the opening is between the front teeth. These fake teeth are sometimes made of plastic and fused to metal bands that are then bonded to the present teeth using resin.
Cantilever Bridges. These bridges are preferred when there are existing teeth on only one side of the broken tooth/teeth in such cases; they're anchored to one or more teeth that are diagonally opposite to the opening. They also are ideal for front teeth since they're at the mercy of little stress.
The fitting of bridges usually takes more than one visit and there after a few more visits to check and adjust them if it is needed. On the first visit, the area that is intended for the bridge is numbed and the adjacent teeth are re-contoured in order to create space for the inward-bound bridges. The dentist may then use a dental putty to make an impression of the teeth that'll be used to make the crown and bridge in the laboratory. The dentist will most likely provide a temporary bridge for protection of the now exposed teeth and gums where the bridge is to be fitted. At this visit, the right shade is also selected to ensure the bridges looks as totally natural as possible when put next to the remaining teeth.
On the second visit, the non permanent bridges will be removed and the bridge that has been custom- made fitted. It is then checked for its fit and bite and any adjustments that are mandatory will be made before it is finally cemented into place. A few more fits will be necessary to check the bridges and adjust the fit. In the case of an enduring bridge, it will cemented briefly for a couple of weeks prior to being cemented permanently to allow for the checking and adjusting of the fit.
Bridges not only restore one’s smile but the facility to speak and gnaw as well. They appear natural in appearance and considering they have a good life period, they're among the safest options to make a choice from if one is looking to replace missing tooth/teeth. Dental bridges also help to maintain the shape of the face and prevent the remainder of the teeth from drifting misplaced.
