CEREC - Same Day Crowns

CEREC same-day crowns are a great way to have a permanent restoration placed without needing to come in for multiple appointments. Same-day crowns are just as durable as lab-made restorations, but they eliminate the need for a second visit. Crowns are essential for covering teeth that have become damaged or compromised. Your crown will last for many years before replacement is necessary.

Cosmetic Dentistry

It's not uncommon to be unhappy with the way that your smile looks. Years of neglect, stains and discoloration can truly take a toll on your confidence. We offer an array of cosmetic options that enhance and correct your existing smile. We can create a treatment plan specific to your needs so that you can finally feel good about the way that your smile looks.


Dental implants are a permanent solution for patients seeking that perfect white smile. Implants are a great choice for patients that have broken, damaged, or missing teeth. Implants act similar to an artificial tooth that is placed in the jawbone. They are extremely durable, and are built to last upwards of 25 years.

Dental implants function like our natural teeth, and allow patients to speak and eat normally. They are comfortable in the mouth, and do not cause gum or mouth irritation like with other restorative solutions. Implants provide long lasting results, and if cared for properly they can last a lifetime.


Dental veneers are shells made out of either porcelain or composite resin material. They are bonded to the teeth and blend in nicely. Veneers match the shade and color of your natural teeth, giving patients that perfect natural looking white smile.

Typically, veneers are used for patients that have misshapen, stained, uneven, or chipped teeth. Veneers are not permanent, but they are durable, and last between 10-15 years. The life of veneers depends on how much wear and tear they face over time.
