New discoveries have found exceptions to Mendel's basic laws, but none of Mendel's things have been proven to be flat-out wrong. Hail to the Father of Genetics ! The name is ma-ma-ma-ma-ma-Mendel.
Dental crowns should last on average from 10 to 20 years. Crowns are still subject to fracture and cavities, so it is important to take extra care in brushing and flossing around crowned teeth to prevent them from needing replacement too often.
So, there are lots of factors that can affect the lifespan of a crown. But on average Iâd say a crown lasts about 10 years. There is great variation in that number too. When my patients ask about how long a crown will last I like to compare any dental work, like crowns to automobiles. Very few people are able to keep a car longer than ten years. Weâve all seen those gorgeous vintage autos of 50 years ago that look like new.
