I noticed this just the other day. The final tooth on the bottom right hand side of my mouth (had all wisdom teeth removed) seems to have the gum growing over it and somewhat pushing it out. If I reach in to my mouth and touch the area of my tooth the gum is covering, it kind of hurts. It also feels uncomfortable when I'm not touching it. When I touch the part of my tooth not covered by the gum it feels fine. What could be causing this, and is there anything I can do?
