Crowns are made of porcelain and cover the biting surfaces of the tooth. They are often necessary with large cavities or when replacing old fillings. A crown can help restore the strength of a tooth.
For a single crown, it generally takes 2 visits. The first visit we file the tooth and take an impression (mold) of the filed tooth. Then we place a temporary crown on the filed tooth to protect it. Three weeks later, we remove the temporary and permanently cement the final crown. With CEREC technology we can complete a crown in a single visit.
Nothing in life is guaranteed. With good home care and routine cleanings and exams, a crown can last a very long time.
Yes. Your natural tooth is still present underneath the crown and with poor home care, decay can occur.
There is no difference – they both mean the same thing.
Bridges are used when there is a missing tooth from an extraction or congenitally missing teeth, and the missing tooth will be replaced by an artificial tooth or pontic. A 3-unit bridge is 3 teeth that are splinted together to replace 1 tooth.
The teeth next to the missing space are filed down, and then an impression is taken. That impression is sent to the lab to begin fabricating the bridge. While the permanent bridge is being made, a temporary bridge covers the filed teeth. Here are some common questions:
No. A bridge is a permanent restoration and is cemented into place. Unlike a bridge, a removable partial denture is taken in and out and clips onto remaining teeth to hold it into place.
Because the teeth are splinted together you must use a floss threader to floss underneath the bridge or a proxy brush to brush underneath the bridge.
