Thank you for your response.

I though of this too – as the bone is more important than the tooth. However, I am still waiting for the infection of the 2nd tooth to go away as it would be even worse if I decide to go ahead with an implant and it fails.

Most likely, I am already suffering from a bone loss as many dentists have reported to me that they can feel the bone being softer than the healthy side. For this reason I have now concluded that I need to have a CT scan to see how bad the bone loss is, so that only inserting an artificial bone is enough. The thought of having to cut off some of my bottom jaw bone (presumably through the cheek?) is very disturbing.
