Often touted as the epic story of the Old South, Gone With the Wind focuses almost entirely on the Civil War (1861-65) and the years immediately following, ending around 1872.
Gums can be healed quite easily. For instance I was having receding gums. My dentist asked what kind of toothbrush I use, I told him a hard one. I felt like it cleaned my teeth better. Turns out hard is for dentures only, and otherwise all people should use soft. My gums grew back in a couple months.
I had Zoom teeth whitening 3 days ago. Apparently, some solution seeped under the protective gum coating and left a nasty burn on my gums. It now looks like a blister or an ulcer. I've seen this reported by a number of people, but no one ever mentions how long it takes to heal (or if it ever does).
