I have 16 root canals

So in my life time (31 now) i got a lot of root canals, only my 4 front teeth on uper and bottom jaw are without root canals.

SO you recommend i put them all out, and then should i get implants or what. I really am confused. I got pains in tooth so they made root canals and pain was gone.

I had changed all my Amalgam fillings years ago.

My main problem is bad breath i have it for 15 years but can not find the cure. I am afraid to be without teeth, what are the option , crowns, if i only have my 4 fron teeth on each jaw.

And i changed Amalgam fillings i thought were the cause of bad breath and it didnt dissapear. It is still here.
