The benefits of getting a bonded dental retainer can be categorized into two major areas. First, from a functional benefit, a dental bonded retainer can prevent unwanted shifting or crowding of teeth. Acting as a "bridge" between the teeth, the dental bonded retainer will hold the alignment and space available for the teeth. In situations where bone loss has occurred and teeth are mobile, a dental bonded retainer can act as a "splint" or support framework for a tooth or groups of teeth.
Second, the esthetic benefit of a dental bonded retainer (as opposed to a wire removable or Hawley-type retainer) is important for patients who want to maintain a straight smile without any visible metal wire or plastic retainer. Because the dental bonded retainer is placed on the inside surface of your teeth, it is the most-esthetic option for maintaining the alignment of your teeth.
