The dental crown and bridge treatment is a long-term method of replacing missing teeth.
A tooth crown is placed on an individual tooth, (somewhat like a thimble over your finger) where there is no longer sufficient tooth structure left to place a filling.

A bridge is placed in a space where one or more teeth are missing in the dental arch. The teeth on either end of the span are crowned, and are referred to as abutments. The false teeth in a bridge that join the abutments are referred to as pontics. The dental crowns and dental bridges are most often made from superior materials such as precious metals (gold), semi-precious metals, porcelain or a combination of metal fused to porcelain.

In the era of modern technology and upgradation, metal free crowns are the best option for replacement.metal free crowns are also known as full ceramic crowns, porcelain crowns and are available under various brand names zirconia, emax, ultradent and so on. Their main advantage over metal and partial metal-ceramic crowns is superior aesthetics ( they look as good as natural tooth, shade matching is perfect) and no staining of crown even in future if proper care is taken regularly.
