Sunbury dentist repairs cracked tooth with dental crown

When out teeth come under attack from tooth decay caused by plaque and bacteria, dental cavities begin to appear in our teeth. If these cavities are not addressed with treatment they will get bigger until the enamel is breached and plaque and bacteria can penetrate to the more sensitive central area of the tooth. This could be the cause of dental infection or abscess that will certainly be painful and often costly to treat.

One way of preventing this from happening is to use a dental filling to prevent the cavity from growing any larger. This involves using dental bonding to fill the cavity and solidify. However, in some circumstances, the cavity may already be too big and will require a greater degree of protection. This is when a Sunbury dentist may resort to using a dental crown. This is an artificial cap that is cemented over the whole part of the tooth above the gum line to protect it from further damage.

The process of fitting a crown first involves the removal of a certain amount of tooth enamel. This allows the crown to fit comfortably over the top of the existing tooth without appearing too large. The new crown, usually made from porcelain but they can also be made from metal including gold and silver, will have been specially designed and manufactured to fit into place. It will then be cemented in place using composite resin bonding.

Dental crowns are also used as the result of a number of other dental processes. For example, after a root canal procedure which is used to remove any traces of bacterial infection in the teeth. Because the tooth will have already been significantly damaged by the infection, a crown will be needed after surgery to protect the tooth from further infection. Dental crowns are also used to repair teeth that have been damaged by dental trauma such as cracks and chips.
