A crown can last for many years. It can also chip, loosen, or leak earlier. How long a particular crown lasts depends on the tooth under it, the bite, and daily care. There is no guarantee that every crown lasts the same amount of time.
What shortens the life of a crown
- Grinding or clenching, which can crack ceramic
- A new cavity where the crown meets the tooth
- Cement that washes out, so the crown loosens
- Biting ice, pens, or other hard objects
- Skipping exams, so a small problem is found late
If you grind your teeth
Ceramic crowns can fracture under heavy grinding or clenching. If you grind in your sleep, a night guard is recommended to protect the crown and the other teeth. A night guard is a separate appliance. It is not included in the $799 crown fee.
Brushing, cleaning between the teeth, and regular exams protect the edge of the crown, which is where new decay usually starts. The fit is checked before the crown is finished. Exact warranty terms, if any, are given in writing at your visit. They are not stated as a number of years on this site.
