Because of perndonal I had my 4 front bottom teeth removed and a Maryland bridge was put in?

The Maryland bridge that was placed 25 years ago was probably made of metal and porcelain. If the supporting teeth are still healthy and in tact, then I would do another Maryland bridge type of restoration. Today it can be all ceramic. This is the simplest and most conservative treatment to do. If there is decay around the supporting teeth then you may opt to have an all ceramic conventional bridge made. If you don't mind the bridge then do another bridge of either type. The other option would be an implant. This is however time consuming and more expensive. Also, many times there is better esthetics with a properly done bridge then with an implant, which is many times difficult when replacing a single lower incisor.

You can make a new Maryland type bridge. A conventional bridge which means you need to remove more tooth on the teeth supporting your Maryland bridge and another option is implants with separate crowns or implants with a bridge.

Maryland bridges are no longer a fad. If your current one can be re bonded, that would be my first choice. Otherwise, consider implants or a bridge.
