How Long Do Dental Crowns Last?
I had 4 Dental crowns "installed" on my lower teeth about 2 years ago and already had one of them break. I am VERY careful about the foods I eat (don't eat hard candy, chew ice, etc) and was wondering how long a Dental crown should last under normal usage.

Crowns can last a lifetime
It is rare for a crown to fail alone, but not uncommon for the patient to fail their crown. Crowns, whether gold, porcelain on metal or all porcelain do not decay. This does not mean that a tooth neglected of good hygiene practice will not decay. Decay under a poorly maintained crown is the most common cause of crown failure in patients I have seen over years of dental practice. Poor hygiene is not the only reason. Although teeth are tools to help us to...

Crown lifespan can vary
Determining how long crowns last is hard to determine. Factors of longevity include:
• Material (full gold vs. porcelain fused to metal core, porcelain fused to non metal core and all-porcelain)
• Location (back tooth, front tooth)
• How much tooth remained when prepared for a crown (was there much there? Was it a heroic effort on the dentist to even try to save the tooth?)
• Bite forces (grinder and clencher, no habits)
• Hygiene practices (some people REFUSE to brush their...

A long time...
Crowns should last a long time. As you know proper checkups and dental hygiene are very important. That being said, 80% of crown/dental restoration failures can be attributed to bire issues, meaning that you may be a grinder or clencher. These added forces to the best dental crowns, will cause them to break. Are your teeth worn down, does your jaw click or pop on opening or closing?, Headaches?, Neck Pain? Theses can all be symptoms of a bite imbalance.

Longevity of Crowns
I have seen crowns lasting as long as fifty years and some fail within a few years. Both cases are rare but could happen pending many circumstances:
Grinding - Stability of Bite
Periodontal (gum) health
Oral Hygiene care
Missing teeth : the fewer the better
Condition of the tooth under the crown : the more tooth structure the better
Condition of your adjacent teeth : the healthier the better
Systemic Health : Such conditions as diabetes...

Factors towards Crown Longevity
Under ideal circumstances Dental Crowns can last for many many years up to a lifetime! When you consider that most Dental Insurance companies are willing to pay for a crown Replacement after 5 Years that tells you that there are many factors that determine Crown Longevity. If the Patient has Clenching or Bruxism habits or perhaps TMJ Dysfunction this can cause premature wear and chipping and thus loss of usefullness of the Crown. Does the patient in question have excellent home...

Broken crown
Tough question to answer. There are so many factors to take into consideration in this situation.
1. Location of the crown may be a factor. Front vs. back
2. Material used. Gold and zirconium are the strongest. Porcelain is strong but must be used in the correct situation
3. Extent of damage the tooth sustained prior to the crown placement.
4. Home care
5. Oral habits. Bruxism, grinding etc.
Under normal circumstances a well placed crown...

The life of a crown...
Most often these fractures happen due to night time grinding and clenching. We ALL do it. Some more than others. When we eat we typically put 80-90 pounds per square inch of pressure on our teeth. Amazingly, people have been recorded at 3000 pounds per square inch in their sleep. I guess your brain just isn't there to tell you to stop!
Typically if you break a tooth or restoration while eating, it was already fractured and just waiting to pop...

Crowns can last decades!
Hi Chipped Crown!
This is a really difficult question to answer. There are just too many factors involved. Many of which depend on the patient that gets the crown, let alone the crown itself.
What I can tell you is that I have seen well done, and well maintained crowns last decades.
Its interesting to note that many insurance companies will pay for replacement crowns after 8 years. Since these companies use their vast accumulation of data to make...

They can last a lifetime.
I don't know your situation, but if the correct technology and materials are used, good dental health is established and maintained, the proper design is instituted, and the dentist and the laboratory do their work ideally I have fould that crowns last indefinitely. Obviously accidents can happen and sometimes (like hitting one with a fork) the initial crack, is not seen or remembered when the crown breaks many months or years later.

How Long do Dental Crowns Last?
It sounds like you are disappointed that your crown is breaking in just two years. Some crowns break because they simply get over-loaded and it shatters the porcelain. For optimal longevity, your dentist will usually describe how to take care of them. For example, watch the hardest foods you eat, don't use your teeth like tools (biting envelopes open, cutting thread...) and many patients ought to have a nightguard to protect from clenching.

Crowns in conjunction with complete dentistry will last many years.
There are many factors to consider when estimating the life span of a crown. Habits such as grinding, ice chewing, and tobacco products with reduce the longevity. The most important factor is for the dentist to perform a thorough exam and develop a complete treatment plan that places the crown in harmony with the rest of the oral system.

Breakage happens
A crown can last 20-30 years or more. Notice I said can. At some point a crown can develop weak points in it and break. Most crowns make it past 2 years, but depending on how it is used in combination with a little bad luck, some fail before then.
If you don't want a dental crown to break, you have 1 option - Gold. Everything else breaks, however the stronger the material, the less likely it will break. Right now I prefer to prepare the tooth for a full contour "emax" crown....

Well-made crowns should last anywhere between 10-20 years
The integrity of a crown is shared between the restorative dentist ansd the lab technician. The dentist should have a proper tooth preparation which includes retention and enough reduction of the old tooth in order to achieve a proper bite. The lab tech should use the appropriate materials and procedures to create the esthetics and durability needed. A crown chip is very hard to fix. You should go back and have a consult with the dentist who placed it.
