i got a filling 3 hours ago now, i had to ask him to give me an extra injection because it still hurt. it is 3 hours later and it is still completely numb, it actually feels like its got worse in the last 10 minutes. I read online dentists can damage nerves and you can be like this permanently. I'm totally freaking out having a panic attack and crying thinking im never gunna be normal again. i dont know what to do.
