NEVADA DIVE FLAG LAW: Remember the State of Nevada requires all divers to remain within 100 feet of a dive flag any time they are in the water snorkeling or scuba diving. This includes dives that originate within swim areas but proceed outside the marked swim area even if the diver remains submerged.
At the second visit, your dentist will remove the temporary crown and check the fit and color of the permanent crown. If everything is acceptable, a local anesthetic will be used to numb the tooth and the new crown is permanently cemented in place.
And in some cases, a post and crown will be required to keep your restoration in place. A post crown is used to treat a badly decayed tooth that doesn't have enough tooth structure left to support a dental crown. Post crowns are most often used following a root canal procedure. A dental post and crown is also used when a tooth is not sturdy enough to hold a crown on its own -- for example, when a tooth has broken off at the gum line. There are three parts to your post crown -- the post, the core and the crown (in fact, a post crown is sometimes referred to as a post core crown). A dental post is a metal rod that provides an anchor for the core, which keeps the crown in place.
