Doubtful: Although patients sometimes think that restorations last forever, the truth is that they don't. That restoration is near your gumline, and is subject to a continuous bombardment of acid from bacteria adhering in that area. This may have caused a premature breakdown of the margins.

Patients who clench or grind their teeth tend to have these restorations break down more quickly. If this continues you may want to discuss a niteguard appliance.
