A dental Crown or Cap is one of the most important tools in the box of tricks used by a dentist. After a lot of work is carried out on the teeth a cap or crown is needed to seal up the tooth and make infections impossible, says a Bootle dentist. A root canal will destroy a lot of the tooth during the procedure and a crown will be needed to seal the tooth back up, it is a routine procedure that is used to get rid of deeply instilled infections within the inner chamber, to get to it the dental surgeon will take out all of the inner part of the tooth. The Porcelain crown may be made before hand or it may consist of a mix made in the surgery, and then sculptured by the surgeon to look natural. If we chip or crack a tooth the chip can be ground out, and then a crown will cover the top of the tooth to hide the missing enamel. A bridge is a crown as it will also need to fit over the anchor teeth either side of the false tooth being fitted. In this instance the anchors are ground down all round to the same size as the inside of the bridge teeth, it is then fitted over the natural tooth and cemented on. There are many uses for a crown and using a new method of making them called the CEREC method, a dentist can make a crown from a blank in the surgery, without using a dental technician to make it before hand.
