Comprehensive Dental Care Chicago, Dental Care Chicago, Cosmetic Dental Care Chicago, Emergency Dental Care ChicagoYour Life Smiles offers state-of-the-art IPS Empress e.max, ZirCAD and Lava All Porcelain Crowns—a new standard in cosmetic dentistry.

That standard is founded in the strength, esthetic, and efficiency these crowns provide. Each crown’s fabrication makes them extremely durable and provides outstanding natural results.

Full-coverage crowns offer maximum coverage, saving 2 to 3 mm of dentin, with minimum invasion. The creation of a beautiful smile often includes porcelain crowns rather than the prototypical porcelain veneer restoration.  Preexisting large fillings or crowns, a history of teeth grinding, challenging ‘bite’ problems and significant lengthening of teeth are some of the reasons why a crown would be preferred. Crowns without a metal core inside offer the best esthetics because of the way they reflect light and the ability to manage the dark (blue) line that can be present at the gumline edge of porcelain fused to metal crown.

Based on 28 years of experience, Dr. Harnois finds the best results are achieved with All Porcelain Empress and “Lava” Crowns.  Lava crowns offer considerable strength over the typical all porcelain crowns due to an inner core made from zirconium.  This core is ‘milled’ through a CAD/CAM process and is carried out at only a select few dental laboratories in Southern California.  Historically; porcelain crowns were significantly weaker than conventional PFM (porcelain fused to metal) crowns and cosmetic dentists were concerned about them breaking.  Also, if the underlying tooth was dark, the typical all porcelain crowns might show this darkness through the crown, making it difficult to match adjacent teeth properly.  The strength and transparency issues are addressed with Lava crowns.  Metal-based crowns have also been known to erode along the gum line, exposing a dark line of metal at the base of the tooth.

At Your LifeSmiles, we use only metal-free crowns in our restorative dentistry procedures. Our Chicago patients often report that friends and family can’t tell their crowns from their natural teeth, and that they are confident their bite is stronger because of the porcelain crowns.


Metal-free bridges are also offered at Your Life Smiles. The Lava restoration can even be used for small bridges; giving dentists an opportunity to replace missing teeth without using any metal.

Restorative dentistry is an important aspect of our practice. Not only do we want to improve your smile, but we also want you to have functionally strong teeth. If you have cavities or have experienced decay, your teeth may need some form of restorative dentistry. At Your LifeSmiles, our metal-free dentistry services give the Chicago area patients the option to preserve the beauty of their natural teeth, while repairing the function of their bite. Cosmetic Dentist, Peter Harnois, both produces restorations that not only protect the tooth structure, but maintain the original beauty of the smile. To find out more about our restorative metal-free dentistry services, contact Your LifeSmiles today.

When plaque and bacteria erode tooth enamel, they can form cavities and areas of decay in the tooth structure. Left unchecked, this can destroy the sensitive nerves and root structure of teeth. Our composite resin fillings are placed in order to stop cavities and restore the bite surface. During the procedure, the decay and only a minimal amount of the original tooth structure will be removed. Composite resin fillings appear natural and are virtually undetectable in your smile. Even if you have previously placed metal fillings, they can be removed and replaced with composite tooth-colored fillings that are beautiful and metal free.
