Minimal intervention bridges, also known as adhesive or maryland bridges are a non-invasive way of replacing missing teeth. They are most predictable around the front teeth and host a very good track record for reliability. The main advantage is that they do not require any preparation of the adjacent tooth, they can simply be glued on and can last for many years.
There is however a possibility that they may fall off, but the bridge can be glued back on easily and efficiently causing no harm to the supporting tooth.
