A Crown or Cap, as its name suggests, is a covering that is placed over the affected tooth. The tooth is prepared by shaping the tooth to be capped. The Cap is then cemented in place to protect the tooth for years to come. Crowns are also used to reinforce a tooth that has been badly cracked or broken, as well as to seal a tooth after root canal therapy.
There are many situations that call for a crown:
Defective Large Old Fillings. If a large, old filling is decayed, leaking, defective, or broken and needs replacement, sometimes the tooth cannot securely hold an even larger filling, and a crown is needed to fill out the tooth’s shape.
Broken Teeth. If there is insufficient remaining natural tooth structure to hold a filling, a crown is needed.
Root Canal Treated Teeth. Back teeth that have had a root canal should be capped to prevent the weakened root canal-treated tooth from suffering catastrophic cracks.
Mal- aligned Teeth. We can sometimes do “instant orthodontics” by preparing poorly aligned front teeth and inserting crowns in a more ideal position to give you a beautiful smile.
A Bridge is a dental device that uses adjoining teeth as anchors to hold an artificial tooth in the place of a missing one. Bridges can be used to replace one or multiple missing permanent teeth in order to avoid more serious problems, such as shifting, bone loss and periodontal disease, often associated with missing teeth.
Crowns and Bridges are mentioned together because the teeth adjacent to the missing tooth must be crowned in order to increase their strength and prepare them to be used as anchors for the Bridge device.
The procedure of creating and fitting a crown or bridge involves two or three dental visits, but is often the most effective way to protect your smile from damage above and beyond a simple missing tooth.
