PFM Crown and bridge
When a tooth is cracked, decayed, or damaged, a crown may need to be fitted onto the tooth. A crown is a permanent covering that fits over the original tooth. Crowns can be made of porcelain, gold and other metals, acrylic resin. Porcelain crowns typically have the most realistic appearance, although they tend to be less durable than others. Crowns can whiten, reshape existing teeth, and create a healthy and vibrant smile.
Preparing the Tooth and Crown
During your first visit, the dentist will numb the tooth to be crowned and remove the decay in or around it. The tooth is then rescultptured to provide an easy fit for the crown. This is a painless process and performed in the dentist's chair.
An impression of your teeth is then taken and sent to the dental lab where permanent, custom-made crowns are created. This usually takes weeks in the UK because of capacity problems. In our Budapest office this procedure takes either five working days or two visits – one day each.
Applying the Crown
On your second visit, the dentist removes the temporary crown and fits the permanent crown onto the teeth. Your dental specialist makes sure the crown has the proper look and fits, and then cements the crown into place.
A bridge is a device used to fill the space where a tooth has fallen out or been removed. A typical bridge consists of a pontic (a filler tooth) that is attached to two surrounding crowns (abutments). Once complete, this bridge structure is bonded into the mouth. Without the use of a bridge, spaces in the mouth from missing teeth can cause multiple teeth to shift, lead to occlusion
Bridges usually require two trips to the dentist's office. During the initial visit, the surrounding teeth are numbed with local anesthetic. The dentist prepares the surrounding teeth by cleaning any plaque or decay that remains and reducing them so that the crowns can be fitted. The dentist makes a mold of the teeth and sends it off to a dental lab where the customized impression is prepared. The customized mold might take few days to return to the office. In the interim, patients are fitted with a temporary bridge constructed of acrylic resin. When the patient returns to the dental office, the dentist removes the temporary bridge and replaces it with the permanent one. The dentist then adjusts the bridge for the proper bite and fit, and the bridge is permanently bonded into the mouth.
