The first toothbrushes were small sticks or twigs mashed at one end to create a broader cleaning surface. The Chinese lay claim to the first bristle toothbrush. Europe adopted the bristle brush in the 17th century, and many dentists practicing in colonial America advised their patients to use the brush.
Bridges are natural-looking dental appliances that can replace a section of missing teeth. Because they are custom-made, bridges are barely noticeable and can restore the natural contour of teeth as well as the proper bite relationship between upper and lower teeth.
Bridges are sometimes referred to as fixed partial dentures, because they are semi-permanent and are bonded to existing teeth or implants. Some bridges are removable and can be cleaned by the wearer; others need to be removed by a dentist.
Porcelain, gold alloys or combinations of materials are usually used to make bridge appliances.
Appliances called implant bridges are attached to an area below the gum tissue, or the bone.
