How Long Should it Last or Will it last?
Saying a crown should last X amount of years is a misnomer and inacurate. Things only last as long as you take care of them. If you are getting a FRONT crown replaced and are 23 consider this
1) Make sure it is all Porcelain NO METAL because as you get older your gumline wil change and if it is metal the grey line will show through. Look into EMpress or Emax depending on strength
2) understand that replacing ONE crown in the front of your mouth is the hardest thing one can do. This may be a good time to bleach your teeth and think about a smile redesign with as little as four teeth. If you do decide that to only do one tooth. Insist on CUSTOM SHADING and a visit to the lab. Make sure your dentist takes lots of photos. If he/she did not suggest any of this look elsewhere.
3) Make sure your gumline is even or your crown will stick out like a sore thumb,
Porcelain Crown for Front Tooth
Placing a single crown on a front tooth of patient is one of the more challenging procedures for a dentist. You want to make sure that you select a skilled cosmetic dentist who works with an experienced cosmetic dental lab. There is nothing more disappointing for both the patient and the dentist to see a crown that does not match in the smile zone. There are many choices of materials to select from when doing an all porcelain crown. One of the most recent porcelains is e.max. e.max has provided us with the greatest strength in porcelain, but allows us to provide an aesthetically pleasing result. You need to consult with you dentist as this may not be the best choice of material for your particular case. As far as longevity, that will vary greatly depending on many factors. Home care, frequency of preventative care visits, your bite, caries rate, etc just to name a few. You generally should expect a minimum of 5 years for a well paced crown on average.

Front Tooth Porcelain Crown Longevity
I get asked this question daily and the answer depends on several factors. Your occlusion (your bite) is very important in the longevity of any restoration. If your opposing tooth hits your crown too hard when you close down you risk fracturing it. If you are a grinder you will need a night guard to protect the crown. Is your hygiene good? Do you get your teeth cleaned regularly? Follow the instruction of your dentist and your crown should last for many years. Finally, if you are having a dental crown done on a front tooth makes sure it is all porcelain/ceramic. Ask your dentist if he uses Emax crowns. These are the strongest, most aesthetic crowns available. Hope this helps.
Longevity of a front crown
Crown longevity is different for everyone. Some people have an ideal situation, take meticulous care of their teeth and they last a very long time. Others might not be good with their home care and the crowns last a short period of time. The real answer is that a well made crown under good conditions will last as long as you allow it to. The strongest, most aesthetic appearing crown for front teeth right now seems to be e.max. It blends the look of porcelain with the strength of metal.
Longevity of porcelain Crown
A well fabricated porcelain crown that is well taken care for by you can last for decades. The challenge on a single anteror crown is to match the shade of the adjacent teeth.
Your dentist is in the best position to pick the best fit for your situation two brand names come to mind that have a good traclk record for longevity: Lava by 3M and emax by Ivoclar, but that is only the beginning of the list.
Often crowns have to be replaced because they chip or crack, sometimes bacause of careleness or accidents on the patient part, like biting on ice or fingernails or falling from a bike, sometimes is fabricaion error, sometimes the bite is setup incorrectly.
Often the crown is still intact but the tooth itself fails due to new tooth decay or root fracture especially if the tooth has had a root canal.
If the tooth has had root canal treatment it can also become discolored over time and ends up looking darker than the adjacent teeth
As you age the cement line near the gumline may become more visible due to recession and/or discoloration
So strenght alone is only one of the factors that determines longevity of your crown,
Careful preparation of the tooth by an experienced dentist with the collaboration of a skilled ceramist who will fabricate the crown will probably give you the best long term results.
A lifetime for a front crown
A dental crown has the potential to last a lifetime. After all, the materials that make up a dental crown do not decay. The lifetime of a crown is dependent on how it is cared for, professionally maintained and treated over time. If homecare is not maintained (i.e. brushing and flossing), more than likely the gums and bone surrounding the crown will degrade and decay will set in along the tooth edge which sits against the crown. Professional maintainence will assist in keeping this area healthy.
A porcelain crown is not unlike Grandma's fine china. Just as you would not bang on the china with hard objects, the crown is not a tool for opening bottle caps, holding roofing nails, biting finger nails or banging with oral piercings.
Other factors which effect crown longevity include design of the prepared tooth, having the proper thickness of porcelain to maintain strength, having a well sealed margin between crown and tooth and insuring that the crown is properly adjusted to the bite and chewing forces.
So long as all of the above factors are considered, the type of porcelain is not so important. There is a vast array of porcelian materials available today. Some dentists and or lab technicians may have a preference over manufacturer, aesthetics, material strength or material cost.
Even though a crown can last a lifetime, on average a crown might be replaced after 10-25 years due to wear and tear or aesthetic changes to the surrounding teeth. A friend who intalls roof shingles had a crown last only a few days, but now he no longer holds the nails in his lips and teeth.
Which Type of Porcelain Crown is Best for a Front Tooth?
The answer to what type of crown is the strongest is a combination of things:
- What your bite alignment is like?
- Do you clench or grind your teeth?
- How far off is the color from the adjacent tooth?
- How well do you clean your teeth and stay on a regular prevention program?
- How skilled the porcelain lab is with each of these different materials?
A front crown can last many years, often from five to twenty or possibly beyond. It will not last your entire life, you will certainly have to replace it later at some point.
I see a lot of patients who are concerned about certain brands of materials or crowns in cosmetic dentistry. While a certain brand can have good qualities, I find far more often the best results come from close communication and coordination between the cosmetic dentist and the ceramist. Some ceramists are very skilled with one material and may have very little experience with another.
Good questions- your local cosmetic dentist should be able to answer them clearly and confidently for you, Dr. Scott Greenhalgh, DDS.
Porcelain Crown Lifespan
There is no lifespan for a well prepared porcelain crown. The problems with most crowns as to why they fail is the homecare. Most people are too rough on their teeth by chewing ice and hard things. A crown can last for years if taken care of.

Lots of good questions here.
Mileage varies from person to person, so predicting how long a crown will last is difficult. Variables include brushing habits, diet, athletic efforts and many more. Normally, we suggest that a crown will last somewhere between 5 and 20 years, often much more. It would not be unusual to predict that you will replace this crown 2-3 times in your life, yet maybe never again.
While there are many brands of porcelain, they are almost all very good. My preference right now is eMax by Ivoclar Vivadent, but Lava by 3M and Procera by Nobel Biocare are great options as well. The list of choices is very long, though, so whatever your dentist suggests is likely a great option for you.
