Dental Crowns; the procedure explained by a Sunbury dentist

A dental crown is a simple enough procedure that most dentists can easily perform, says a Sunbury dentist. One of the most common reasons for a crown is after a root canal has been done, the root canal treatment removes the top of the tooth, or the front part, in order to allow the dental surgeon to get right into the inner chamber. The crown is made from Porcelain usually, and is made up on site to make sure that it looks as natural as possible. They are also known as a cap, and some of them are made off site by a dental technician to order. A cracked tooth or a chipped one will be taken care of by grinding down the enamel to illuminate the damage, then the crown will replace the missing part. It is generally fixed in position using dental cement, and will cover the whole of the ground down tooth. They are extremely hard wearing and will outlive the natural enamel on the other teeth. These days the cap or crown is used for a multitude of dental problems, worn teeth caused by grinding of the molars is a common enough one. Even teeth that are discoloured are being fitted with crowns. It isn`t always the first choice for many of these problems though, as veneers do to some extent also cover these problems. They last as long as a veneer which is between 5 and 15 years depending how you car for them, but like a veneer they can easily be replaced at any time.
