My dentist has recommended implants over bridges but why?

It’s very difficult to say without having a full comprehensive examination of your dental health.

Essentially a bridge relies on the 2 teeth at either end to support it.  If these are “Virgin” ie untreated healthy teeth then they will have to have part of the tooth removed for the bridge to bond and attach to the tooth.  If the tooth has been weakened by previous treatments such as large crowns, fillings or root canal treatments then using it as a bridge support (pontic) could place stresses on the tooth.

There are many factors to consider; how big is the gap? where in the mouth?

Dental Implants can be used to support bridgework without using any of the surrounding teeth.  The implants themselves, act in a similar way to your natural tooth roots.

I hope that this answers your query.
