How Long Can A Dental Crown Last?

Dental crowns or sometimes called caps by the general public are used to restore teeth with large decay or larger broken fillings.  The crown helps to strengthen the damaged tooth and allow it to return to normal function.  Crowns are also used after a tooth has a root canal procedure wherein the nerve of the tooth has been removed due to infection leaving the tooth vulnerable to fracture.  The crown helps to keep the pieces of the tooth together.  If an individual loses a tooth and undergoes an implant which is a way of totally replacing a missing tooth the crown restores the part of the tooth you see in your mouth. Crowns can also be used for cosmetic reasons such as to replace the color of yellowed or stained teeth or teeth which are too small or misshapen.

Dental crowns are made of different materials.  In the past crowns would be made of gold.  Gold is very biocompatible with the mouth and wears the most similar to your actual teeth.  This prevents the tooth opposing the crown from wearing evenly over time.  Today most individuals will not accept the yellow color of gold so most crowns now contain porcelain which can be matched to the color of the patient’s teeth. Porcelain fused to metal gives the esthetics of porcelain with a metal substructure to support the tooth.  This is especially useful in teeth which have undergone root canal therapy and need additional support.  Today there are also crowns that have porcelain on the outside but instead of metal core a ceramic one is used to support the porcelain.  The advantage of this combination is that the crown can be even more esthetic and is a good choice for patients who have metal allergies.

Crown treatments require two appointments.  The first is when the actual tooth is put back together and an impression is taken to send to the lab which makes your final crown restoration.  On the second appointment your new crown is bonded onto the prepared tooth structure remaining in your mouth.  During the period between the two appointments which is generally several weeks a temporary restoration is placed in your mouth that allows you to continue to function normally.

So how long does a dental crown actually last?  Most crowns will last for many years.  A gold crown could last a lifetime.  The problem with crowns versus your own tooth is that your own tooth is a complete structure while the crown is like a hat on your head.   There is a crown margin all around your tooth where the crown ends and your tooth begins.  This area over time can develop decay causing the crown to fail.  Your part in this scenario is to brush and floss your teeth twice a day every day.

You need to keep this crown margin clean.  Also since porcelain is glass and you will apply a tremendous pressure to it when chewing there is the possibility of the porcelain breaking.  A crown prep is a large restoration on your tooth and sometimes the nerve within the tooth will die or become infected.  If this happens a root canal will be needed which can reduce the longevity of your tooth.

Insurance companies which do not want to pay for re-treatments believe if a crown lasts five years it is a success.  However crowns can last anywhere from 15 to 20 years.   At this point the crown may still be successful but from an esthetic standpoint the patient may want to replace it.

Go For The Gold

With the Olympics coming to Beijing, China in February 2022 the goal is to go for gold. In dentistry you can also go for gold. With a gold filling or if you’re brave a gold crown. Obviously, the gold crown would need to be on one of your back teeth unless you’re going for the bling.

Most individuals today will not accept gold due to its color. In fact, most people prefer not to have yellow teeth to begin with and will undergo bleaching or cosmetic dentistry to lighten the shade of their teeth. In California, you can never be too-blond, too-tan and have too-white teeth.

In fact, today the demand for gold dentistry is predominantly by dentists. That should tell you something. Just like you, dentists do not like going to the dentist. They make like performing dentistry but not having dentistry. When it comes to dentistry women are a lot stronger than men. Something about lying on your back with a stranger working a couple of inches from your brain can cause men to panic.

Back to gold. The reason dentists choose gold is that it lasts the longest. Gold has the same expansion and contraction as enamel. Meaning, gold is the closest to what the outside of your tooth is made of. Gold is very biocompatible with your mouth.
It is easy to clean and its edges can be very closely adapted to your tooth structure. In fact, most dental restorations are wide open. Meaning the armies of bacteria inyour mouth are marching in mass into the interior of your tooth. Since cementing mediums contain huge amounts of fluoride this helps to keep your teeth protected.

The great draw back to gold is that it is yellow and you can see it and in today’s esthetic conscious society Moi is perfect in every way. Sort of like: Only your hair dresser knows for sure. Here at the practice, we still do gold crowns and gold fillings. If the need arises this alternative will always be presented and then promptly rejected.

The cool thing about gold is when you melt it. It looks like mercury except it is gold in color. You can actually see your reflection in it and before it becomes liquid it has a reddish golden sheen. Just magnificent and it makes you realize why it has been in use since antiquity. However, at 1948 degrees Fahrenheit you certainly don’t want to touch it for then you’ll definitely be singing, but not in a good way.

But even today it continues to remain the gold standard in finance and in dentistry.
