@ 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 kenyandentist@yahoo.com and ill call you back.

Kamundu thank you for your much valued advice.

Now,having been to a dentist before and seeing how they blow out moisture before surgery,I thought that I could imitate the same to allow the glue to hold.
So I brushed the foundation and applied salt to disinfect,It would be horrible for germs to breed in between,Then I thoroughly wiped dry the tooth before glue application.It is still very firm.
I will drop you a mail to explore the other options.

Uchokozi galore, yes go find the hymen and glue it back, you become a virgin instantly..
