A dental crown does the important job of restoring a damaged or decayed tooth when the area is too big for a filling. Dental crowns can also be used for dental work such as root canal treatments and tooth implants, restoring form and function to your bite. If you’re wondering ‘how long do crowns in teeth last’, read on because we’ve got the answer for you.
What Affects The Lifespan Of Dental Crowns?
Lots of variables need to be taken into account when considering the lifespan of a dental crown, including
- The position of the crown in your mouth
- The type of material used
- The size of the crown and the amount of natural tooth remaining
- The skill level of your dentist
- Your habits: if you bite your nails or grind your teeth, you could affect the lifespan of your crown without realising it.
- Your standard of oral care matters too. If a restored tooth undergoes more decay, it could result in you losing your crown prematurely. Read more about it.

Zirconia crowns
Zirconia crowns are classified as ceramic dental crowns. They are very durable and fracture-resistant. With good oral care, zirconia crowns can last for 10 to 15 years.
Porcelain fused to metal
The natural end result of porcelain fused to metal makes it a popular choice for a dental crown. Porcelain and ceramic crowns tend to produce the most natural-looking result. On average porcelain fused to metal crowns can be expected to last between five and 15 years, but they may last longer with good oral care.
Gold
A popular choice for dental crowns, gold is strong and bonds well with the teeth. It can be combined with other materials to reduce the cost and still produce a robust dental crown. Crowns made from gold usually last for longer than 10 years.
Composite Resin
All-resin crowns are inexpensive to create but they tend to wear down much faster. Sometimes resin shrinks when it dries and may need to be adjusted to fit the natural tooth properly. The composite resin may last for four to eight years, depending on the placement of the crown.
So, How Long Do Crowns In Teeth Last?
On average a dental crown can be expected to last for between 10 and 30 years, depending on the material used. It’s a good idea to discuss the different types of materials available before moving ahead with treatment.
By looking after dental crowns you may be able to extend their lifespan:
- Don’t use your teeth as tools
- Don’t chew ice or bite on anything that isn’t food
- Brush and floss your teeth twice a day
- Visit your dentist twice a year for a check-up and professional clean
- Wear a mouthguard at night to protect your teeth against grinding, which could potentially loosen a crown.
