A crown is a restoration that fits over the remaining part of you tooth making it resilient and giving it the look of a real tooth. Crowns can be used to restore teeth that have been broken or that have been weakened by decay. A crown may also be the ideal solution if you have a discoloured filling and you would like to improve the appearance of the tooth; or if you have had a root filling you may need a crown to protect what is left of the tooth.
Bridges are ideal for people only have one or two teeth missing and do not want a denture. Bridges can be made by crowning the teeth on either side of the gap and attaching a false tooth in the middle.
