Dental Bridge

Gap Between Crown and Bridge

I have a gap between my two front teeth. One of the problems I am facing about that is that one of them is a dental crown and the other is a part of a dental bridge. Is there a way to close this gap with Lumineers or should I have them replaced?

Dear Candace,

How do you fix a gap between your teeth?

I’m going to say right off the bat that your dentist should NOT have placed these where they left a gap. He obviously does not care about appearance related dentistry. However, what is done is done and you can only move forward from here.

Typically, a dentist will fix a tooth gap by using dental bonding, but that will not work well with your dental work. There is a method that can do it but stains usually develop within a relatively short period of time.

As for Lumineers over crowns, the Lumineers company actually ran a campaign promoting that some years back that ended up flopping for reasons I’ll explain in a moment. However, even if it were a good option, I would definitely suggest you see another dentist to have it done. Your dentist does not appear to care about the aesthetics of his work, just the function. That is not a quality you want in a dentist for any type of cosmetic work. You’d want a skilled, artistic cosmetic dentist.

Bonding porcelain on porcelain, which is what would happen in the case of using Lumineers, is never as stable as bonding porcelain to natural tooth structure. Because of that you risk two sets of bonding failure. One from the original dental work and another from the Lumineers placed on top of the dental work.

When you consider it is an equal amount of work for the dentist to just remove the old dental work than it is to place new over old, you can see why the campaign failed.

That is actually what I will recommend for you. Have your dentist, or better yet a more skilled dentist, redo your dental crown and dental bridge so that there is no gap. Make sure they only use a porcelain crown on your front tooth.

Can I Place New Lumineers Over My Old Ones?

Hi,

I got Lumineers placed on my teeth years ago, and they are not as white as I’d like them to be. I know that porcelain crowns can’t be whitened with tooth whitening or bleaching, but I was wondering about something else I could do. Is it possible to place new, whiter Lumineers over my old ones? Is it recommended? I just want my smile to be brighter.

Thank you,

Julia, from Accident, Maryland.

 

Hi Julia,

Lumineers are an ultra-thin type of porcelain veneer marketed as a no-prep procedure, meaning they are bonded directly to your tooth without any surface preparation. Your dentist should have taken your smile concerns into consideration while making your Lumineers. Not getting the color you wanted is probably a result of your dentist lacking experience in cosmetic dentistry. A true cosmetic dentist would take your aesthetic concerns as seriously as your practical ones.

Fortunately, you can get a brighter smile if you re-do your old Lumineers. Putting new ones over your current ones will not save you any time or money, and may also feel too thick when placed in your mouth. Bonding Lumineers on top of existing ones or porcelain veneer increases the risk of failure. Also, the thin margin between where the Lumineers meet would be more prone to staining than if it were placed over a natural tooth.

So to improve the whiteness and look of your smile, you should seek out a cosmetic dentist to replace your Lumineers. Cosmetic dentistry isn’t a specialty recognized by the ADA, but some dentists have received extensive post-graduate training in cosmetic and restorative dentistry, and have the experience to help your case.

Also, be open minded when seeking a new dentist for your Lumineers – not all dentists are comfortable using them, and you may find that a different type of porcelain veneer is best for you.
