How long do dental crowns last?

On average, dental crowns last between five and 15 years. The life span of a crown depends on the amount of “wear and tear” the crown is exposed to, how well good oral hygiene practices are followed, and your personal mouth-related habits (you should avoid such habits as grinding or clenching your teeth, chewing ice, biting your fingernails and using your teeth to open packaging).

Does a crowned tooth require any special care?

A crowned tooth does not need any special care. However, the underlying tooth still needs to be protected from decay or gum disease. Therefore, continue to follow good oral hygiene practices, including brushing your teeth at least twice a day and flossing once a day -- especially around the crown area where the gum meets the tooth. Also avoid biting on hard surfaces with porcelain crowns (for example, chewing ice and popcorn hulls) to prevent cracking the porcelain.
