A dental crown is an artificial covering placed on top of a natural tooth to protect it.
The most basic type of crowns which were used traditionally in earlier times are metal crowns. These are made from nickel and chromium material and offer good strength, durability in back teeth. But these are hardly used these days due to the unaesthetic appearance in the mouth and the demand for metal free dentistry. Nevertheless these are sometimes indicated in back teeth after root canal therapy.
These crowns have a metal base for strength and a ceramic coating on the top for the natural look. These are the most popular type of crowns these days.
These are one of the best available crowns in the market these days. Zirconia crowns are “metal free”. Zirconia is one of the strongest materials known to dentistry.

Another popular option amongst youngsters these days is the E max crowns. These crowns are known for their high translucency and extremely natural appearance and are frequently used for front teeth.
Another Category of Metal-Ceramic crowns is the DMLS crown where in the core of the crown is manufactured by Laser Sintering.
A dental bridge is an artificial prosthesis which bridges two teeth on either side of a missing tooth gap.
Bridges can be made from the following materials
The procedure involves preparing the supporting teeth for the bridge on either side of the gap by recontouring the enamel and making space for receiving the bridge
Occasionally root canal therapy may be required if there is not enough room for the crown based on your biting pattern.
The next steps involves taking impressions of the preparation and sending it to the lab for fabrication. Shade recording is also done.
A trial visit is given occasionally to check the fit of the bridge prior to insertion. In the final visit the bridge is cemented into position and your bite is assessed.
After an initial period of about a week to ten days you get completely accustomed to the bridge. However it is important to report for regular check up as we assess the hygiene status and prompt you if there is any lapse in maintenance.
