Dentistry has come a long way, but despite improvements in dental care, many people still suffer from tooth loss.  This can be from decay, periodontal disease or injury.  For the longest time the only treatment options available for people with missing teeth were bridges, partials and dentures.  Dental implants changed this, and in many situations gave us a much more acceptable and predictable option.  Put simply, dental implants are replacing the tooth root.  They provide a foundation for the teeth they will be supporting, thereby, simulating your natural teeth.
