Crowns are placed over a tooth when a large portion of the tooth is lost ot decay or has broken off. Usually when a filling is more than half of the size of the tooth, the tooth is weakened. If the filling would comprise a significant portion of the tooth, often the tooth can fracture under the stresses of chewing and therefore, placing a crown over the tooth protects the chewing surface and prevents that from happening. Crowns that are white are made of porcelain and are usually placed in areas of esthetic concern. Gold crowns might be placed in the molar region or when there is heavy grinding that might damage the opposing teeth.
Dentures are false teeth.
Dental implants, simply put, are typically titanium posts that are imbedded into the jawbone and then plastic or porcelain teeth are placed over the portion of the implant that sticks out of the gums. They usually take several months to complete since the bone must fuse to the posts before any kind of pressure can be put on the implant itself. Nutrition and Dentistry.
