Implants are a secure alternative to removable dentures. Sometimes they may be an only option if the loss of teeth has caused the mouth to shrink that can no longer support dentures. Implants have revolutionized the replacement of missing teeth. They basically recreate the basic structure of a tooth, which no other treatment alternative can offer. It is a titanium screw that is placed in the place of the root part of the tooth. It is surgically placed into the jawbone and over a period of time topped with a precisely crafted ceramic crown. An implant can replace a missing tooth but approximately as few as 4 implants can replace all the upper and lower jaw teeth. This number is dependent on the size of your jawbone. The longer the implant, the fewer implants would be needed to support the replacement of more number of teeth. This option would feel and act the most like a natural tooth while chewing, smiling or brushing. When smiling, or talking there is no way one can tell the difference between the natural tooth and an implant.
