Cosmetic Dentistry

Gaps in your smile can really make you feel self-conscious about your appearance.A woman smiles | Cosmetic Dentistry St. Paul MN

At Highgrove Dental Care, it is one of the cosmetic dentistry concerns we address most often so that our patients can feel good about the way they look. We address the gap issue in a few different ways depending on your needs.

Cosmetic Dental Bonding

Cosmetic dental bonding uses the same highly esthetic material that we use for tooth-colored fillings. We can match the correct shade to your teeth, and your end result provides a seamless look. Cosmetic dental bonding works best on small gaps or slightly misshapen teeth that are not involved directly in chewing.

Porcelain Veneers

If you have wide or multiple gaps in your smile, you might consider porcelain veneers. Veneers are thin tooth-like restorations that cover the front of your natural tooth and provide you with a new smile profile.

Veneers can even correct the appearance of misalignment, shortened or worn teeth, and non-uniform teeth.


We want the best for our patients, and in some cases, orthodontics may be the most appropriate solution when it comes to closing the gaps in your smile. Even short-term cosmetic orthodontics can move your teeth enough that additional cosmetic dentistry is more effective.

If you would like to address the gaps in your smile, contact our St. Paul dental office to schedule a consultation with Dr. Terry O’Neill.

So, any teeth with or without restorations can get cavities without proper oral hygiene. That being said veneers are often placed over teeth with multiple unsightly composite restorations.  The integration of veneer to tooth is nearly seamless and is less likely to have decay than most other dental restorations.

Veneers allow you to cover stained or discolored teeth and to shape your teeth for a perfect smile. That being said, a lot of people wonder how long dental veneers will last, just like any other dental restoration.

The longevity of dental veneers is quite remarkable.  They are considered a permanent restoration and are as long-lasting as other dental permanent restorations.  Statistically, one veneer per hundred per year is the often quoted rate of breakage.

Metal Crowns

You most likely have a porcelain fused to metal crown which has tooth-colored porcelain baked on to a metal substructure.  What you see is the line of metal below the porcelain after your gums receded slightly.  New technology allows the fabrication of all ceramic crowns without metal.  So, there is no dark line even if your gum tissue recedes.

what are veneers | cosmetic dentist st paul mnThrough the use of dental veneers, we are able to solve a variety of small cosmetic dental issues that may plague your teeth. Dental porcelain veneers are a very lifelike and natural looking long lasting restoration used to improve the appearance of your teeth.

How Are Veneers Put On

The procedure involves permanently bonding a very thin but strong custom-made porcelain facing on to the front of your tooth. This shell bonds with your natural teeth, giving you a seamless appearance that is not noticeable to others.  The color, shape, texture, size, and or position of your tooth can be improved by using porcelain veneers. We can also use veneers to fill in the gaps in your teeth giving you a flawless looking smile! If you want the smile of your dreams in less time, than dental veneers may be the right option for you! For more information on porcelain veneers, please don't hesitate to contact our friendly, St. Paul, MN dental team.

At that time there was a very large study that determined that there was no permanent damage done to teeth by whitening teeth with current methods. Since that time tens of millions of people have completed teeth whitening without permanent problems.
