How long should a porcelain crown last on an upper jaw tooth?

A porcelain crown on an upper jaw tooth typically lasts between 10 to 15 years, depending on factors such as oral hygiene, the location of the tooth, and personal habits like grinding or clenching. With proper care, including regular dental check-ups and good oral hygiene practices, some crowns can last even longer. However, individual experiences may vary, so it's important to consult with a dentist for personalized advice.
