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.
How long dental crowns will last depends on many other factors in addition to the material they are made of. Practicing good dental hygiene by brushing and flossing twice a day will increase the life of your crowns. You can also increase crown life by limiting consumption of hard or crunchy foods.
