I have temporary partial at the moment, so it is not the best fit.
But it already has me thinking about implants and the whole process of implants scares me, but then they are mini implants which I have heard you don't need as much bone for and they heal a bit faster.
If you bone has shrunk you may need a bone graft too for the implants.
They are expensive though.
Implants may not be the best of you are diabetic but I am not sure on that
I know that dentures can also be secured to your mouth by implants, so they look more natural and you won't have anything covering the roof of your mouth.

If the teeth are infected could he not do a root canal? I know everyone always says to get a second opinion before removing any teeth.
