Committed to Excellence in Dental Care

At Glen Ellyn Dentistry, Dr. Charise Petrelli and Dr. Cathy Nguyen combine their extensive experience and education with their artistic eye for pleasing aesthetics to provide patients with the highest quality treatment outcomes. Our dentists believe that exceptional dental care is found at the intersection of science and art. So, Dr. Petrelli started our dental practice in 2006 to bring the art of dentistry to our patients and community. 

We love the Glen Ellyn community, and our entire team is proud to be a part of it. In our office, we strive to reflect Glen Ellyn’s small-town feeling where neighbors and friends care for each other like a large family. We enjoy getting to know each of our patients, their families, and their oral health care goals so that we can build lifelong relationships with our patients and help them create beautiful, long-lasting smiles.

Whether you’re looking to restore your well-loved smile to its complete form and function or have an infant whose first teeth are just erupting, our dental team provides a positive experience in our office and an excellent treatment outcome. 

Preventive Dentistry

Preventive dentistry aims to keep smiles healthy by creating a foundation of good oral hygiene with treatments designed to fight tooth decay and the harmful bacteria that lead to gum disease.

Cosmetic Dentistry

Every smile is beautiful, but cosmetic dentistry can help you create the ideal smile you envision for yourself.

Restorative Dentistry

Teeth can become damaged due to a variety of factors, and restorative dentistry works to address damage to restore the health of your teeth.

Our team goes above and beyond to ensure you enjoy the time you spend in our dental office. Our office environment is clean, welcoming, and comfortable, and we take special care to always treat all patients with kindness, compassion, and professionalism.  

During treatment, we ensure your comfort by using a gentle touch while thoroughly explaining the steps we are taking throughout your treatment. Additionally, we schedule adequate appointment times throughout the day so that we have plenty of time to pay close attention to detail, explain treatment options, and answer any questions you might have while you are in our office.

We provide a comprehensive list of general, preventive, restorative, and cosmetic dentistry treatments and services in addition to several specialty services, including Invisalign, the Pinhole Surgical Technique, the Bioclear Method, and a variety of minimally invasive treatment options using Biolase Waterlase laser dentistry. 

Additionally, we specialize in providing advanced dental restorations with tooth-colored fillings, dental crowns, and dental bridges.
