Many people ask how many years a porcelain crown will last. The answer depends on the material, the bite and each person's care habits.
- Porcelain crowns usually last about 10 to 15 years, sometimes longer or shorter depending on the person.
- Material, bite, the natural tooth and oral hygiene decide how durable a crown is.
- A loose crown, a gap at the edge, pain or sensitivity, inflamed gum or cracked ceramic are signs to have it checked.
- Careful cleaning, avoiding hard objects and regular check ups help a crown last longer.
A porcelain crown does not have a fixed expiry date like a household item. Usually a crown is expected to last about 10 to 15 years, in many cases longer, though some need replacing sooner. The exact time depends on several factors.
What decides how long a crown lasts?
- Material and workmanship: the type of ceramic, how closely the crown fits and the quality of cementing all affect durability.
- The natural tooth underneath: a healthy tooth and healthy gum keep the crown stable.
- The bite: people who grind their teeth or bite unevenly may chip or crack the ceramic, see daytime grinding and clenching.
- Oral hygiene: plaque at the crown margin can cause decay or gum inflammation around the crown.
- Eating habits: biting very hard things such as bones or ice raises the risk of cracks.
Signs a crown needs checking or replacing
- The crown is loose, has a gap at the edge or often traps food, see what to do when a crown comes off or breaks.
- Lasting sensitivity or pain in the crowned tooth.
- Swollen, red or bleeding gum around the crown, or a bad smell.
- Receding gum showing a dark line or metal edge, see dark gum line around porcelain crowns.
- Chipped, cracked or clearly discoloured ceramic.
How can you make a crown last longer?
- Brush properly and clean between teeth daily with floss or a water flosser.
- Avoid biting hard objects, opening bottles with your teeth or biting nails.
- Wear a night guard if your dentist advises it, see what a night guard is.
- Have regular check ups so the dentist can examine the margins, gum and bite, see also how to care for porcelain crowns.
