Without much knowledge of dentistry, it is unlawful that you will have more than a passing knowledge of what the difference between crowns and implants are, and no real knowledge of when either one is appropriate.
As you would imagine, crowns are basically coverings that are placed over unhealthy teeth in order to retain a biting surface and attractive appearance. They also help to support surrounding teeth and guard against the gum disease and bone loss that can be caused by missing teeth. Implants, on the other hand, are where a metal rod is inserted into the actual jaw bone which then fuses with it, and replacement teeth are attached to the part of the rod which protrudes above the gum line.

A crown can not just cover up empty space, so material such as amalgam or composite resin, or in some cases a post and core can be used to build up the tooth in preparation for a crown. If a post and core is required, it is unquestionably that there is enough healthy tooth left to justify the use of a crown rather than an implant.

Your choice of material depends on what property is most important to you; strength or color match. The strongest crowns are undecidedly metal crowns. These … More
