A composite filling can be done in one visit. First, the tooth is numbed if necessary. Then we polish the tooth or remove the decay. A conditioning gel is applied and rinsed off. Then the tooth is sealed with a sealer that is cured by a harmless high-intensity light. Next, the bonding resin, or composite, is applied and sculpted into the proper shape and hardened with the same high-intensity light. Finally the tooth is smoothed and polished and the bite is checked.
A crown takes two visits to complete. At the first visit, the area is numbed. Any decay is removed and the tooth is reduced and shaped with a handpiece. Sometimes, to help make a more accurate impression, retraction cord is placed between the tooth and the gums to gently push the gums away form the tooth. It is taken out before taking the impression. Then a temporary crown is cemented in place. In two weeks, the crown will be delivered. At this second visit, the temporary is removed and the new crown is tried on. The fit and bite are checked and adjusted as necessary. When everything looks good, the crown is cemented into place. Finally, the excess cement is removed.
To begin the process of making a denture, impressions of the mouth are taken. From these impressions, precise working models of the mouth are made. It is on these models that the denture is fabricated. When the denture is ready, the remaining teeth are extracted. Patients are thoroughly numbed before any teeth are removed, and should feel no pain. As soon as the teeth are out, the denture is placed. For the first 24 hours the new denture will feel tight because the gums are swollen. As the bone and gums heal over the next six to nine months, the gums will shrink and the denture will begin to feel loose. When this happens, a temporary lining material is used to tighten the fit. After this period of healing, when the shape of the mouth has stabilized, the denture is sent back to the lab and relined for its final fit.
An extraction can be completed in one visit. First the tooth and the area surrounding it are thoroughly numbed. Then the doctor works the tooth to loosen it and make sure the tissue is numb. Then the tooth is carefully extracted. More difficult extractions, such as teeth with more that two roots, are referred to an oral surgeon.
Partial dentures are made the same way as a full denture (see Dentures). The only difference is that partials only replace a few teeth, not all of the teeth. Partials have clasps that fit around existing natural teeth. These clasps hold the partial in place and keep it from moving around. Partials have the advantage of allowing the patient to retain as many of their natural teeth as possible.
A root canal takes two visits to complete. At the first visit the tooth is numbed and an opening is made through the top of the tooth down into the pulp chamber. A series of dental files are used to carefully clean out the infected nerve tissue and shape the canals to receive the filling material. An x-ray is taken to make sure that all of the infection is removed. Then some medicine is placed in the tooth and it is filled with a temporary filling. At the second visit the tooth is reopened and filed once more. Then an inert filling material is placed in the canals of the tooth. Another temporary filling is placed and the root canal is finished. The patient will then come back for a final, permanent filling, or another type of restoration depending on the situation and condition of the tooth. For further information please follow this link:
