Sensitivity after a filling

Several months ago I had a filling placed. It was fine at the time, but then a few weeks later the tooth became sensitive to cold. Do I need to replace the filling?

When a tooth feels fine immediately after a new filling is placed, but then becomes sensitive later, that usually means that there are bacteria from the original decay that had penetrated into the pulp of the tooth. Generally, you wait it out and hope your normal body defenses kick in and deal with it.

The key as to whether you need to do anything will depend on if the sensitivity is getting better or not. If the sensitivity is improving, then you probably don’t need to do anything. If, however, the sensitivity is getting worse, then it is possible you will need to get a root canal treatment. If so, you’ll also need a dental crown.

Who checks with the insurance company

If I need a dental procedure, is the dentist’s office responsible for finding out if my insurance will cover it or am I?

How this works will depend on the dental office you go to for your care. Some dental offices don’t accept dental insurance, because they prefer to set their own fees. In that case, the patient is responsible for all of the cost and generally it is paid upfront.

With dentists that do accept insurance, many times the office will help you in knowing how much the insurance will cover and how much you will be responsible for.  Your insurance will not cover everything, so you will have a portion to pay. The amount they estimate for you before insurance is just that–an estimate. If the amount ends up being more, because the insurance paid less than expected, that is still your responsibility.

Sensitive composite filling

I had some composite fillings placed on my teeth. I’m not having pain or sensitivity. But, one of the fillings feels a little uncomfortable when it is pressed. My dentist has already replaced it once.  Does he need to do it again?

Though I couldn’t be certain without seeing your tooth myself, I really don’t think you have anything you worry about. It is not uncommon for there to be some sensitivity to your white fillings for several days.
