Glans is the tip/head/non-skin end of your penis and it should not have been touched during circumcision. Maybe by mistake something happened. But there are body tissue structures that are removed and lost forever from circumcision. Namely the "rigid band" and part or all of the "frenulum" So a restored foreskin is not quite the same. But people who get circumcised as an adult and then later restore say that restored is about 70-80% as good. And far better than nothing!
