Sensitive Tooth ?

[DEN53]

I had a large filling replaced last Thursday - 3 numbing injections in the gum and then the day after I had a massive cold sore appear on the corner of my mouth (same side as the filling).

My question is - I know the cold sore is throbbing but my tooth is still sensitive - do you think this is normal ?

You could also try rubbing a little sensodyne actually on the tooth it does help!
