Dr. Hall,
I had monolithic zirconia crowns put on all top front teeth. (Didn’t know they would be solid white.) My upper lip sticks out now. There are dentist more than willing to replace but I wonder will using a different crown material make a true difference. One dentist even said ‘I’ll fix your duck lip with new crowns” That comment didn’t help my self conscious feeling. Also I read that removing zirconium crowns can be difficult. I don’t want to end up with more problems in the long run and spend a bunch of money for bad results.

Dear Gayle,
I’m not having good feelings about either dentist you’ve seen about these crowns. Neither one of them seems to have facility with appearance-related dentistry. The first botched the color and didn’t position the crowns right. The second shows a level of insensitivity that suggests that he or she doesn’t have an ability to deal with patients’ cosmetic dentistry issues. As I have stated elsewhere on this site, my guess is that only 1-2% of dentists have the ability to create a beautiful smile.
Before I recommend a course of action for you, let me give you some insight into the problems you have experienced.
Zirconia is an excellent material for crowns. It is a ceramic that is provided to the dental lab as blocks of material that are then milled by a computer-driven machine to fit precisely on your tooth and to be shaped into a tooth. Since it comes from a block, the appearance can’t be customized to be colored exactly like a tooth—teeth have gradations of color. So when a zirconia crown is placed in the smile zone, it needs to be veneered with porcelain. Porcelain is applied as a paste to the crown and then baked to a final restoration. In applying the paste, a laboratory technician can blend in a variety of colors. A skilled technician can use porcelain to faithfully reproduce the appearance of a tooth so that an observer can’t tell that it’s not a real tooth.
When zirconia is veneered with porcelain it is called layered zirconia. When it isn’t veneered it is called monolithic zirconia. Monolithic zirconia is totally inappropriate for a front tooth. It can never look completely natural. A dentist who would try to do that has little knowledge of acceptable aesthetic dentistry.
And then, on top of that, your dentist had your crowns placed too far forward. When a dentist does one or two crowns on front teeth, it is easy to tell how far forward to put the front surface of each crown. When all of the front teeth are crowned, it takes a higher level of expertise, which your dentist apparently didn’t possess.
So, what to do now? You need to find an expert cosmetic dentist to fix this for you.
The best assurance of finding an expert cosmetic dentist is to find one who is accredited by the American Academy of Cosmetic Dentistry. To become accredited, they have to pass rigorous written and clinical examinations that assure the examiners that they know what they are doing and have the needed artistic ability to create a beautiful smile.
But there are also some expert cosmetic dentists who have elected not to pursue the accreditation program of the AACD. They should all, however, be able to show you photographs of their beautiful work. I wouldn’t trust a dentist to do crowns on all front teeth without seeing some photographs of similar work.
A note about the cost. While some excellent cosmetic dentists charge very high fees, many have fees that are in line with other dentists in their area. However, I wouldn’t expect any of them to be cheap. They have to use the best materials and the best laboratories, and have to be willing to take the time to produce a beautiful result. So if you’re looking for cheap dental work, don’t expect it to be beautiful.
