Unlike other body parts, teeth can’t heal. That means, if a tooth structure is lost, its lost forever. It can never grow back. The oral cavity is a dynamic environment where changes occur constantly, sometimes quickly, but more often slowly, over time. Changes can be due to a traumatic accident, missing teeth, periodontal/gum disease, shifting teeth, a lifetime neglect, a destructive habit such as grinding, or a lifetime of dentistry focusing on one tooth at a time and leaving the mouth resembling a patchwork quilt. All such negative changes that happen in and around teeth become cumulative if not addressed at an earlier time, thus resulting in loss of function and a worn down aged smile.Commonly, patients visit dentists to treat the worst tooth in the mouth, while the rest of the teeth are left deteriorating. There are many problems with this plan of treating issues, rather than treating causes. There is always a cause for the deterioration of the teeth and until that cause is addressed, the teeth will continue to shift, decay, chip and wear away until there is little left for eating and smiling. Thus, it is much better for you to get the causes treated and prevented along with complete rehabilitation to stay away from future problems.
