Crowns and Bridges
A crown means removing the outsides of a tooth down to the gum margin so it completely covers the tooth.
Crowns may be made of porcelain, gold of various metal competitions (see below), porcelain bonded to gold, Cerec, zirconia and various other similar materials.
For a crown to succeed, there has to be sufficient tooth to support the final structure. Sometimes when there is insufficient tooth material left to support the crown, it is possible to build a core in the middle, sometimes supported by steel or titanium pins.
If there is insignificant tooth material for even this it may be necessary to remove the nerve of the tooth, root treat the tooth, then place metal posts or resin fibre posts in the route canal with a core on top of that, as above and a crown on top of that. One or more crowns, especially at the front, can dramatically improve the appearance of the mouth or indeed the person as a whole, restoring personal confidence and producing a personal well being.

Bridges are, in the main, two or more crowns linked together by 'floating crowns' filling spaces between the teeth.
Bridges are not removable by the patient so are fixed structures. For bridges to be successful, there is a arithmetic calculation to be worked out as to whether there is enough support gained from the other teeth.
For those who like arithmetic it goes as follows: the surface area of the root of the missing tooth is imagined: this must be less than the surface area of the roots of the teeth to support the bridge have to be greater the surface area of the teeth. For a tooth that’s lost more than 30% of their boney roots it cannot used for bridge support. For further solutions visit dentures and implants.
