Restorative dentistry refers to oral procedures and management performed to keep your mouth functional and healthy. These include such things as crowns and bridges. The main concern of restorative dentistry is to keep the mouth functioning as best it can. In the process of doing so, it can also improve the overall look of one’s smile. While there is overlap between cosmetic and restorative dentistry, the former is more concerned with aesthetics, while the latter is more concerned with function and health.
