Keep praying =)
Im in a similiar situation i have no more back molars at the bottom of my jaw BUT the wisdom molars, & half a broken molar, My 4 front teeth Are fake & real (hard to explain) Theres a thing that they can needle in fake teeth in you, BUT i really dont want it, it gets hard because sometimes i start thinking when they fall i wont be able to chew... BUT before i start being dragged into panick mode i calm down & remember God heals & helps, if he gave life again to people that died then can give life to my jaws again so they can re grow teeth & molars in a position were i would be able to chew, i have sinned in the past for this to happen so i dont EVER ask why why me, because i know why, maybe not all the reason why but i know mostly why.
A thing im ashamed off, i already asked God for forgiveness many times Even in tears. Im pretty sure he forgave me but maybe now its being used for other reasons to protect me so for now im having patience & having faith in him =D
Because he gave me the wisdom molar to grow before that other last molar broke so i can still chew.
Dont get it amputated keep faith =D if he made men walk who NEVER walked in their past then he can make your arm move which once moved & when that happens NEVER think it was a doctor or something because it was ONLY God & God himself a miracle he made =)
I prayed to God for you & please ask God for forgiveness for all your sins & for whatever sin you did to cause that to happen.
No one is perfect we all sin & God knows that , but we can try to walk in his way & pray for him to help us walk in his way =D
& for him to forgive us for our sins.
