Those place, on my upper jaw, ever since I got my wisdom teeth taken out, they just feel so weird! It's like tooth, tooth, tooth, smooth flat fleshy gum surface with a slight indent.
Where I got my bottom teeth out, they were impacted (meaning stuck in the jaw bone), which took more effort to get out, but more gum grew back in their place, so I'm sorta trying to make some of that gum stretch a little or something so I can fit my toothbrush there easier.
This is the kinda of random stuff that I notice when I only have three days of classes this week and don't have my first final until next Tuesday. Ahhh yeah!!
