Dentistry is the application of the science of placement, arrangement and function of teeth, as well as their supporting bones and soft tissues. Unlike other human tissue, the dental structures cannot repair themselves hence requiring regular care to maintain their health and vitality.Tooth decay is one of the most common diseases and accounts for almost half of all tooth extractions. Almost 80% of the population in developed countries have experienced the problem. However, dental restoration (fillings) do not last forever, hence 60% of restorative dentistry is done for replacement of restorations. Restorative dentistry refers to the restoration of natural teeth that have been damaged, decayed or lost. Crowns and bridges are the major part of restorative dentistry, along with the permanent implants. Inlays, onlays, and veneers are also part of restorative dentistry to some point. Patients are keeping their teeth later in life so practitioners are looking for new restorative solution that can increase the teeth’s life. Teeth that might have been extracted in the past are now restored with the use of crowns and bridges.
A crown is constructed to restore a damaged tooth back to its original form and function and a bridge is used to replace one or more teeth.
