A dental crown is a cap, usually made of metal, porcelain or a combination of both, that is used to cover a natural tooth that has been heavily decayed, is structurally weak or has cracks through the tooth structure. It may be recommended after a root canal treatment or if the existing tooth has a very large filling.
A crown not only restores the shape and function of the tooth, but also strengthens the remaining tooth and helps retain a natural tooth for a longer time.
Your dentist will inform you if you need a crown and make recommendations about the material that would be most suitable for that particular tooth.
If crowns are well taken care of with proper brushing and flossing at home and regular dental check ups with your professional, they can last for a long time.
A dental bridge is a fixed prosthesis that replaces one or more missing teeth. It consists of an artificial tooth (or teeth) that extend across the missing space, and which are anchored by crowns on natural teeth on either side of that space.
Although implants are generally the ideal treatment option for missing teeth, a bridge may still be a good option in certain situations.
You need to be diligent with brushing and flossing around a bridge to maintain the health of the natural teeth supporting the bridge and also the health of the gum at the missing tooth site.
