While they may not be the first thing people see when you smile, your back or posterior teeth are key to maintaining good oral and physical health. And just because you can’t see them doesn’t mean you can forget about them! By not replacing missing back teeth, you will also lose the bone that supports them. You run the risk of bite collapse as well as a decrease in your chewing efficiency thus impacting your dietary choices. Losing back teeth causes your face, cheeks, and lips to sag—in short you look old. To make matters worse, you can also experience excessive wear or erosion of remaining front teeth because they are receiving more stress as fewer teeth are handling the workload. Once you’ve decided to replace your missing teeth, your options include implants or fixed bridgework.
