Founded in 2006, Arnold Smiles, the practice of Drs. Erin Mariscal, Sarah Graesser and Megan Fasanella, provides general dentistry to the entire family. Through the use of state-of-the-art equipment and with a focus on comfort, the dentists are able to provide an array of services to patients-- even those with dental anxiety. Modern tools like digital X-rays reduce appointment times, and amenities like television screens on the ceiling and massaging dental chairs in treatment rooms make patients feel at ease in a spa-like setting. Nitrous oxide is also available to help ease patients who have more serious cases of dental anxiety.  

Looking for straighter teeth fast? Arnold Smiles has the solution for you. Six Month Smiles is a short-term orthodontic treatment that uses clear brackets and tooth-colored wires as an alternative to standard metal braces. There is little debate within the orthodontic community that braces are the most widely used and most effective method to give patients straight, healthy teeth and a beautiful smile. Six Month Smiles has taken the best aspects of braces and modified the treatment and the materials to give adults a common-sense, cosmetic solution that fits your lifestyle.

If you want to whiten your smile fast and effectively, consider teeth whitening at Arnold Smiles. We offer affordable options to our patients, as well as a number of whitening solutions to choose from. Call today to schedule a teeth whitening session, and treat yourself to a gorgeous, brilliantly white smile!

Located right off I-55 at Richardson Road, Arnold Smiles is open 7 am to 7 pm most days to accommodate busy families and working professionals.
