Crowns (also referred to as ‘caps’) are indicated when a lot of tooth substance has been lost for example where a tooth has a large filling or has been root filled. They are made by preparing the tooth to a peg shape, taking a mould of the tooth and the laboratory technician constructing a tooth shaped ‘shell’ to fit over the prepared tooth – restoring it’s form and appearance.
Sometimes if a great deal of tooth substance is lost a post crown is used. This is a tooth replica, which is held in place by a post/peg in the root of a root filled tooth. Crowns can also be used for purely cosmetic reasons. To disguise discoloured teeth or make teeth appear straighter.
Many people have gaps in their mouth where teeth have been previously removed and there are several options for filling these gaps.
Bridges are porcelain or ceramic teeth that attach to adjacent teeth either via a crown around the adjacent tooth or by sticking on the back of adjacent teeth. These are most suitable for small gaps.
Implants can be used to fill any size of gap and consist of titanium screws that are placed in the bone and act as a new tooth root. Porcelain or ceramic crowns are then placed on top of the implant.
Each option has it’s own merits and are more suitable for certain patients. A consultation with a dentist will enable a full range of options suitable to you to be presented and thoroughly explained.
