Three years I had a failed root canal and lost a lower molar. I have had a partial that has worked well. Now I find that I may need to have three or more lower molars removed. Question: Has anyone got experience with the metal implants that hold the lower partial in place. I expect that I will be missing 4 or perhaps 6 molars. I.m scared to death of what will happen, as I have read of so many people who cant make the lower dentures work. I still have all my front lower teeth. Thanks
