Today I had to get a cavity filled. The dentist numbed the area with a "shot". I had my appointment at noon and wasn't hungry - so I didn't eat before I went. If this ever happens to you - have lunch BEFORE you get a tooth filled. The entire side of my face was numb all day and I was starving, but afraid to eat, because I would have probably chewed the side of my face off due to the extreme numbness. About 4pm - I felt a major tingling and then all of a sudden - I wasn't numb anymore. Very weird - I thought about what it would be like to numb other parts of the body (what would you numb if you could??) xoxo A.Joy
