Sydney,
I'm in total agreement with your specialist about implants instead of root canals. I see so much jawbone infection caused by root canaled teeth that I personally, would never have one done on any of my own teeth. Dental implants are a foreign matter (titanium in the US and zirconium in Germany)that can pose certain risks, but under healthy circumstances, they are quite remarkable!

Keep us posted on your husband's journey with this second implant! Hopefully it will work out ok!
