Fillings and sensitivity

I got fillings in two of my bottom teeth a couple of weeks ago. I'm still feeling a little pain when I chew on that side and I'm extremely sensitive to anything cold. Is this normal or do I need to get the fillings redone? 

I've been told that your teeth can remain sensitive for a month or more. I would try staying away from sweets and drinking hot teas. Give it some time if the pain isn't too bad. If you just can't take it, I would def just to to the dentist. Good luck
