My porcelain-fused-to-metal crowns are ugly

Monday, January 31st, 2011

For more than twenty years I have had crowns on my two front teeth. They are porcelain-fused-to-metal crowns, as was normally placed back in the day. They have never looked all that great, but in recent years they have really started to look terrible. There is a dark line right where the crowns meet my teeth, and it is really noticeable because  I have a really big smile.

Is there anything that can be done to get rid of that line? If I have to replace the porcelain crowns, do you think Lumineers would work for me?

I appreciate your help with this.

 Dear Mallory,

There really is not anything that can be done to disguise that black line, which as you have pointed out is one of the major drawbacks of porcelain-fused-to-metal crowns. You also touched a little on the other issue with porcelain-fused-to-metal crowns when used for front teeth — they don’t look very good. Porcelain-fused-to-metal crowns are too opaque to look realistic in the front teeth.

You will need to get them replaced with porcelain crowns, and Lumineers might be an option. But the best advice I can give you is to see an experienced, artistic cosmetic dentist for this procedure. Any dentist can claim to do cosmetic dentistry, but you’ll want one who has training, experience and talent. Smile makeovers require a rare balance of artistry and science, and only a small percentage of dentists have it. Make sure you choose the right professional, and you may have a smile you love for the first time in many years.

Are CEREC crowns a good option?

Monday, January 17th, 2011

I travel a lot, and time to get any kind of appointment taken care of is in short supply. I recently had an emergency root canal done on an infected tooth (one of my first premolars) while I was on the road, and the dentist said I would probably need a porcelain crown. I am home at most for a day during the business week, and my dentist does not work weekends at all.

I called their office to see what we could work out, and they said that they have new equipment that lets them place crowns in just a single visit, called CEREC crowns. They said this would probably work for me, but they want to examine me before making the appointment to place the crown. That is OK, as I don’t want them to race into anything and try to place something they shouldn’t just to get it done.

My concern is that I have been reading about CEREC crowns on the Internet, and some of the sites are talking about them not looking as realistic as the other kinds of porcelain crowns. I am in sales, and my appearance is critical. I can’t have an obviously sub-standard repair on a tooth making me look cut-rate. My customers are upscale professionals in an appearance oriented industry. All I really want to know is if CEREC crowns can be made to look as realistic as any other kind of porcelain crowns.

Dear William,

It is reassuring to hear that your dentist will not race ahead with the crown appointment before taking a good look at your situation. CEREC crown placement does not work for everyone.

The first premolar is visible when you smile, so you are correct in stating that a sub-standard job at matching your other teeth would be noticeable. Your question as to whether or not a CEREC crown could be made to look realistic earns a qualified answer: it depends on the skill level of the dentist using the equipment.

You state that the dentist’s office “just” got the equipment, which may indicate that your dentist is not yet very experienced with obtaining optimal results. Ask about your dentist’s training and credentials, and pay particular attention to his or her professional affiliations. Membership or better yet accreditation with the American Association of Cosmetic Dentists  (AACD) is a very promising sign that your dentist places a high value on aesthetics. It is also a good idea to ask to see some before and after pictures of actual crowns that your dentist has placed. If he cannot produce any, this could mean that he simply lacks experience with the equipment, and you might be better off with a traditional porcelain crown.

You don’t say that the affected tooth has started to darken, so you have time to make decisions. Best of luck.
