Dental Crowns

How many kingdoms do you rule?  If you have many crowns you could be an emperor.  Teeth have a hard life.  Continually they are under pressure from chewing, grinding and clenching.  The outside of your tooth is covered with enamel, a very hard substance that gives strength to your teeth and helps prevent decay.  However, bacteria are tenacious and over time can make a small hole in the enamel and access the inner surface of your tooth.

The inside of your tooth is made up of dentin which is not as strong as enamel.  The decay that attacks your teeth is anaerobic meaning it likes areas without oxygen.  Once inside your tooth there is no oxygen present and it is warm and dark making the bacteria even happier.  If the bacteria take off and eat too much of your tooth you may need a crown to preserve the tooth in your head.

A crown is like a girdle.  It holds your tooth together.   Crowns are made of different materials.  A metal crown is quite strong but not too attractive.  The best crown is made of gold which has the same expansion and contraction as your own teeth.  A gold crown can have a very thin margin and have the best fit on your tooth.  However, the gold color may not be acceptable for most patients esthetically.

Today we have tooth colored crowns which will match the color of your own teeth.  Most patients prefer this type of restoration.  There are several types of porcelain crowns we can use based on the condition of your tooth.

A crown after being placed may not make you a queen or king for life but it will save your tooth.

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.
