Excellent crowns and bridges were made by the Etruscans in the 7th cent. B.C. At about that time, teeth were being extracted in Asia Minor as a cure for bodily ills and diseases. Skills achieved by the Etruscans, Phoenicians, Egyptians, Greeks, and Romans were largely lost during the Middle Ages, when barbers and roving bands of charlatans practiced unskilled dentistry at marketplaces and fairs. Abulcasis, a Spanish Moor, was one of the few in his time who studied dental surgery.
Your teeth are by far one of the most important things you use every day. Many people end up neglecting their teeth with improper oral hygiene. You should take care of them by brushing at least twice a day, flossing once per day, and going for regular dental checkups at least twice per year.
The classic metal orthodontic braces are the most familiar method of teeth straightening. Consisting of a bracket glued to the front of each tooth and a metal wire connecting them, orthodontic braces usually require several years of wear for effective teeth straightening. They can be uncomfortable, expensive, and embarrassing for older patients. However, they are still the most effective method of teeth straightening and can correct overbites and underbites as well as individual teeth alignment.
For individuals who are looking for a fast way to achieve dramatic teeth whitening results, in-office whitening is the way to go. Protective gel is applied to the gums, lips and other tissue around the teeth, and then a bleaching solution is applied to the tooth enamel. A high intensity laser or other type of light catalyzes the bleach, and the teeth are treated for one to two hours.
Be sure to discuss with your cosmetic dentist that the cement color used for your permanent crown will be the same as used for your temporary crown. A try in paste is used for this purpose. The color of the cement does affect the overall color of a porcelain crown, so this needs to be discussed long before your temporary crown is placed.
