How long do dental crowns last?

I am a 36 year old male. I got a dental crown last year. How long do dental crowns last?

Dental crowns are precision engineered and are designed to last a lifetime. The tooth underneath may fail if teeth are not cleaned effectively or if gum disease affects the bone around the roots or if the nerve of the tooth dies and the tooth needs a root canal treatment. Crowns don't fail but tooth roots do
15 years is the average lifespan for a well maintained dental crown.

Anywhere from 5-30 years.

Good for you for getting the treatment you need. The goal of any good dentist is to get a crown to last as long as possible. They usually brag about how they have had a crown last 30 years. This is certainly the exception but it is not unobtainable. Insurance companies will usually pay to replace a crown every 5-10 years depending on the plan and company.
Crowns can fail in a couple different ways. First, depending what the crown is made out of, the porcelain can chip off. While this is not an immediate problem it can cause a gap between your teeth which traps food. While this is annoying it also usually causes a cavity below the crown. Secondly, crowns fail because of a cavity. Crowns cover the tooth and the crown itself does not decay; however, there is always an edge where the crown meets the tooth, and this is where a cavity can form.
If either of these happen, you usually need to replace the crown. Hope this helps.

My best to you!

Most insurance will pay for replacement every 5 years. Crowns need not be replaced unless they become defective
The American Dental Association recommends 5 years minimum. Insurance companies also recommend 5 years. On average, should last 15 years.
The average age of crowns vary on the hygiene and dietary habits of the patient. The insurance standards are usually followed which cover crowns again in 5 years and recently they are increasing it to 7 years and some pay for redo crowns after 10 years. We have patients who have same crowns for 25 years so there is no set time and a lot of factors regulate that.
As long you keep the crown clean with brushing and flossing and regularly see your dentist, a crown can last many years.
