Crowns are a type of dental restoration which, when cemented into place, fully covers that portion of a tooth which lies at and above the gum line. In comparison, composite fillings/inlays/onlays are dental restorations that are used to fill in or cover over just a portion of a tooth. Since dental crowns encase the entire visible aspect of a tooth, a dental crown in effect becomes the tooth's new outer surface.
Crowns are used to rebuild broken or decayed teeth, to strengthen teeth, and as a means by which to enhance the cosmetic appearance of teeth. Crowns can be made out of porcelain/ceramic, gold alloy, or a combination of both. Dental crowns are often referred to as "dental caps".
If you are missing teeth and having trouble speaking or chewing, or are noticing strain when biting, bridges may be the ideal procedure to help make your mouth healthy and beautiful again. Bridges literally “bridge” gaps between teeth by filling them with strong, natural-looking artificial teeth. Bridges are semi-permanent – they can only be removed by a dentist – and are comfortable and proven to strengthen teeth.
