Dental Crown question?

When my dentist permanently cements in crowns, he JUST puts the cement in the crown and thats it.





I thought they had to use some sort of primer first. If they don't is the crown just as durable?

Two main issues deal with how well a crown stays in place once seated. The stump needs to be as dry as possible and a very good cement used. No, a primer as you put it is not required. Once the crown is lined with cement and placed over the tooth stump a thickness of gauze or some other material is placed between your crown and the opposing teeth. You are then instructed to close and bite down. This presses the crown down and helps squeeze out the excess cement. However, it's best if you bite down, hold for about ten seconds, release the pressure for five seconds and then press and hold until told to release. That action allows all excess cement to squeeze out. A single closure can trap cement on top of the stump causing the crown to not completely seat. After seating and the cement has set, the DDS should use colored disclosing strips to check your bite for balance and to insure the crown isn't to high.
Reply:It depends on what kind of cement they use. There are some that are a two step process, but most of them you just mix and apply. If the tooth is dry, the cement and crown should stay no problem.
