@ kysse it really depends on how much of the tooth remained inside the bone after the fracture. If it is sufficient, we use that as a foundation and place something called a post into one of the roots, then build up the tooth with a material called composite ( that build up is called a core) Then lastly we bond a crown onto that core to ensure the tooth doesnt fracture again.
All back teeth (premolars and molars) with root canals need crowns, otherwise they will fracture at some point. You see they are essentially dead hence brittle.
If your fracture was way below the gum level it will be hard to place a crown and Im afraid you will have to lose the tooth. But not to worry there are many options of replacement out there such as bridges and implants
If you have further questions drop me an email on
