    Hello! I had a composite filling done almost 4 weeks ago and my tooth is still sensitive to cold. The dentist said the cavity was a bit deep. So i'm wondering if this is normal, or whether it will gradually go away ? I don't have any pain in the tooth, for example, when I bite on it. I only have sensitivity to cold. I've heard it could take a while for sensation to go away if, for example, the cavity is deep. So i'm just wondering if anyone has any idea about this ? Thanks!

    Any drilling to your teeth may result in some sensitivity. The pulp (nerve center) becomes inflammed. Try to minimize cold sensation because it can damage the nerve. How you know the nerve is damaged is if you have intense pain that wakes you at night. That is when you may need a root canal.
