A crown is used to restore a tooth that has had significant decay, a previously treated root canal system, fractures, wear etc. Crowns are also used to restore esthetics and in some cases, malalignment. Crowns can be made out of a variety of materials. Your dentist will help you decided the best option for your case. Crowns are typically full coverage for your existing tooth. Additional procedures may be required prior to crown placement.
A bridge is a great option to replace function and esthetics to a tooth that is missing or has been extracted. It is often a preferred option to replacing a missing tooth with a removable partial denture. A bridge will be supported by existing teeth that situate beside the area of the missing tooth. A variety of materials can be used to fabricate a bridge and your dentist will help you find the best option for case. In some cases, a less invasive bridge can be used (a Maryland Bridge) that will not require significant removal of existing tooth structure. Ask your dentist for more information.
