Dental crowns are not only necessary for a beautiful smile, if they are on a back tooth they provide a surface with which to chew food. Dental crowns are expensive. There are two types of crowns, temporary and permanent. Dental patients more often tend to swallow a temporary crown, since the adhesive used to hold it in place is more likely to fail and the crown may be dislodged while chewing a mouthful of food and swallowed before you know it’s missing. Less frequently, this happens with permanent crowns but when it does, you can recover the crown and have it reattached.

What is a Â dental filling?
A tooth consists of enamel,dentine, pulp and cementum. Enamel is the outermost layer which forms the crown of a tooth. Tooth surface is covered by a bacterial biofilm,known as plaque. The bacteria metabolizes sugar and releases acid which destroys the enamel. This process is called decay or dental caries. When oral hygiene is inadequate, dental decay progresses into the dentine layer and in later stage, into the pulp. Decayed tooth is weak and brittle, thus it becomes soft, forming what is called cavity. A tooth damaged by decay needs to be filled to restore its normal function, shape and strength.
