Crowns & Bridges
Crown Placement Over Tooth
A crown is placed on an individual tooth. If you have a decayed tooth or a tooth that has a large filling a crown can be placed over the tooth to prevent the tooth from fracture or having further decay that may lead to root canal. The first step to creating crown is to numb the patient. The next step is to prepare the tooth by removing any decay and shaping the tooth so that a crown can fit on it. To create the crown an impression is taken of the tooth with the ITERO machine. The ITERO machine is a 3D machine that can take an image of the prepared tooth and entire mouth. The image is used to create a temporary crown to be placed in the same visit. The image is then sent to the lab where a permanent crown is made. This process can take about a week or two. After the permanent crown is made, the patient returns to have it cemented.

Bridges Fill Gaps Between Teeth
￼A bridge is needed when there is a missing tooth or teeth. The process for creating a bridge is similar to a crown. The patient must be numb and the teeth must be prepared. An imprint of the teeth is taken and sent to a laboratory to have the bridge made. Bridge models can be created using the ITERO machine in the office but the process is time consuming. In most cases it is best if the patient comes back at a later time to complete the bridge.
The bridge will be constructed with porcelain fused to metal or all porcelain. This depends on which teeth are affected. Metal and porcelain is better for back teeth especially second molars which is usually the last tooth in your mouth. The back teeth need to withstand more pressure from chewing and grinding. Porcelain is a better choice for the front teeth as it looks more natural and creates a beautiful smile.
