Predicting the life expectancy of a dental crown is extremely challenging. Many factors affect their longevity: your oral hygiene, how often you visit the dentist, the technique used by the dentist, and the biting force applied to the dental crown.
Research has shown that the average success rate of a dental crown is between 5 and 10 years. However, I have seen countless caps last more than 20 years in my office.
One important aspect of the longevity of a dental crown is the tight contacts that it makes with the adjacent teeth. A loose contact, one where the floss goes right through without a snap, can lead to food getting trapped when eating. Accumulations of food next to a dental crown can obviously lead to gingival inflammation and caries developing underneath the cap. Thus, tooth crowns need be in strong contact with adjacent teeth. Dr. Lissauer discusses this topic further in his blog post titled “Prevent food from getting stuckf your Link“.
A little about me and my experiences with dental crowns:
After graduating from Tufts Dental School, I completed a residency at Boston City Hospital. Following the residency, I worked in a practice near Boston while teaching at my dental school for a few years. My wife Joanne and I then decided to move to south Florida, where I have practiced for the past twenty-five years. Over this time, cosmetic dentistry has become my passion, especially making beautiful dental crowns. In the office, we make sure that every crown blends absolutely perfectly with our patients’ natural teeth. If the color of a dental crown is slightly off, we add a little color and bake the crown in our porcelain oven until it is the perfect shade. Also, we want every crown to look gorgeous and last as long as possible, so we only use the highest quality porcelain. If we are making a porcelain-fused-to-metal crown, we only use high precious metal. In addition, to make every crown, we confidently believe that we use the best dental laboratory in the country.
