How long do dental crowns last?

On average, dental crowns last between five and 15 years. The life space of a crown can depend on the amount of “wear and tear” the crown is exposed to, how well you follow oral hygiene practices and personal mouth-related habits. These mouth-related habits can include things like:

  • Grinding or clenching your teeth.
  • Chewing ice.
  • Biting your fingernails.
  • Using your teeth to open packaging.

Does a crowned tooth require any special care?

A crowned tooth doesn’t need any special care. However, the underlying tooth still needs to be protected from decay or gum disease. Because of this, you should continue to follow good oral hygiene practices. These practices include brushing your teeth twice a day and flossing once a day — especially around the crown area where the gum meets your tooth. Also, avoid biting on hard surfaces with porcelain crowns (for example, chewing ice or popcorn hulls) to prevent cracking the porcelain.
