What has caused fracture of GIC filling within a month?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I had a type 2 cavity filling in one of my molar teeth. It was a GIC filling. Just after the filling, they did scaling of all the teeth. I asked them if I should wait for an hour after the filling, but they did it anyway. Now, after a month, the filling broke.

What do you think the reason might be?

But I did not chew any hard foods after the filling.

Please help.

Thank you.

Hi,

Welcome to icliniq.com.

In your case, there might be the following reasons.

1. Uneven biting pressure. It may cause the filling to break in class 2 cavities, especially as walls of the tooth are involved and sometimes, unintentionally, the person bites with slight uneven pressure, resulting in the breakdown of the tooth filling.

2. Water or saliva contact right after filling. Usually, a half-hour gap is given after GIC filling for water contact, for eating and even for drinking water. If scaling is done right after filling by putting a separating medium on the filling, there can be chances of water contact through the scaling procedure that causes the filling to become porous, and it might break.

Now you can go back to the dentist and ask him to do a composite filling instead of GIC, as it has more strength. After the composite, there is no need to wait; you can have direct water contact, too.

I hope it helps.

Thank you.
