Some patients have a crown which lasts the rest of their life, while others have a crown which becomes loose or cracks shortly after the placement. Because there are various factors which impact the life expectancy of a crown, there are no guarantees. In general, patients can expect a crown to last about 15 years. While a majority of crowns last at least eight years, it is common for insurance to cover a crown replacement if it is needed just five years after the initial placement.

A crown which does not fit well is often due to issues associated with the dental laboratory. When evaluating your options, it can be helpful to ask the dentist if they have a good working relationship with their dental lab and are happy with their results. The dentist may even be able to provide references. When considering dental crowns, the dental lab is nearly as important as the dentist who is providing treatment.

The guard can help protect the crown and natural teeth.
