Why do I need to replace a missing tooth?

When a person loses one or more teeth, the neighboring teeth can shift, tip or even "super-erupt" into the space. Teeth that have drifted from their normal and healthy position are often more susceptible to decay and gum disease. Perhaps even more important, this movement can lead to changes in a patient's bite that can ultimately put stress on the jaws, muscles, teeth and the temporomandibular joints (TMJ). Over time this can affect a patient's ability to chew and may even change the facial appearance depending on the location and number of missing teeth.
