Routine checkups

Although a routine checkup may not be seem important, it provides the best predictor when something might be starting to become a problem. A cavity usually takes at least three weeks before it will be evident on an x-ray. Once it does, it commonly indicates that the cavity is larger in your mouth, since an x-ray is only a 2-dimensional picture of a 3-dimensional cavity. Routine  appointments every six months reduces the chances that a simple cavity normally fixed with a filling, would turn into a root canal and crown problem.
