Helping Patients Smile with Confidence
You deserve a dentist who approaches your smile with artistry, precision, and a commitment to lasting results. Creating a beautiful smile is both an art and a science—often bringing together multiple treatments in a carefully personalized plan.
Dr. Rallis has completed extensive advanced training in cosmetic and comprehensive dentistry and is Dawson-trained and a member of the Dawson Academy faculty. His experience allows him to thoughtfully restore and enhance smiles with treatment designed around each patient’s individual needs, goals, function, and long-term oral health.
What Makes Us Different
Exceptional dentistry is rarely one-size-fits-all. Dr. Rallis takes a collaborative, comprehensive approach to treatment planning, looking beyond individual teeth to consider the health, function, aesthetics, and long-term stability of your smile. When a patient’s needs call for additional expertise, Dr. Rallis collaborates with experienced specialists, including periodontist Dr. Chris Chondrogiannis, to thoughtfully coordinate care.
This team-based approach allows us to develop a personalized treatment plan designed around your individual needs, goals, and long-term oral health.
More Than Dentistry
Our commitment extends beyond exceptional dental care. We’re proud to be part of the Bayside community, building meaningful relationships with the patients and families who have trusted us with their smiles for generations.
For us, dentistry is about more than treating teeth. It’s about caring for people, giving back to our community, and making a positive difference both inside and outside the dental office.
Custom Cosmetic Dentistry Options

Smile Makeover
A personalized combination of cosmetic treatments designed to improve the appearance, balance, and overall harmony of your smile. We create a customized plan based on your goals, facial features, and dental needs.

Porcelain Veneers
Thin, custom-crafted porcelain shells can transform the shape, color, and proportions of your teeth. Veneers offer a natural-looking solution for addressing chips, discoloration, gaps, and other cosmetic concerns.

Teeth Whitening
Brighten your smile with professional teeth whitening designed to safely and effectively reduce stains and discoloration. We’ll help you achieve a noticeably brighter smile while keeping your results natural-looking.

Invisalign®
Straighten your teeth discreetly with Invisalign® clear aligners. This comfortable, removable treatment can improve alignment and bite while allowing you to maintain your normal routine throughout treatment.

Composite Fillings
Restore damaged or decayed teeth with tooth-colored composite fillings that blend naturally with your smile. These restorations provide both functional support and an aesthetically pleasing result.

Full Mouth Reconstruction
For patients with multiple dental concerns, full mouth reconstruction combines restorative and cosmetic treatments into one comprehensive plan. We carefully coordinate each phase to rebuild function, health, comfort, and confidence.
