Crowns are a very strong, permanent type of restoration. Once they are cemented into place, the portion of a tooth which sits at and above the gum line are completely covered. In comparison, fillings (made of resin or plastic) are restorations meant to fill in or cover only a portion of the tooth. Crowns are used when your dentist needs to rebuild severely broken or decayed teeth or as a way to enhance the cosmetic appearance of teeth. Because a dental crown covers the whole visible part of the tooth, we can often change the shape, colour, and even the alignment of the teeth using this type of restoration. Crowns are made out of porcelain or ceramic material or metal (gold or alloy), or a combination of both. Sometimes this type of restoration is referred to as a "dental cap”. Crowns and caps are the same thing.
If you are missing teeth and are self conscious of the gaps in your smile, a dental bridge may be a good option for you. Bridges literally “bridge” the spaces in between teeth. We fill these gaps by adding strong, natural-looking artificial teeth that are permanently cemented in place. A bridge is often a good option for tooth replacement when implants are not possible or as an alternative treatment that does not require surgery.
