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. Dental crowns or restorations may be inhaled or swallowed by the patient during chewing food, sleeping, laughing or yawning or may be during some accident. Patient should be told not to get panic and stay calm if he/she has swallowed a dental crown. Continue reading

Examples of all ceramic crowns
Traditional porcelain jacket crown (PJCs) is the oldest type of tooth coloured crown and it consists of 1 – 2 mm thick of porcelain. PJC is relatively brittle but after it is cemented it requires same amount of force to fracture our tooth enamel. To overcome the brittleness of PJCs, many types of stronger crowns have been developed.
Zirconia cores is another type of all ceramic crowns. Zirconia is a very strong material but it is dense white and required thick layers of porcelain underneath to mask the opacity of zirconia.
What is a 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.

They lack the bonding mechanism when compared to bonded fillings which restore 85% of strength that the tooth had before the first filling. Continue reading
