We welcome patients of all ages and backgrounds. Routine care, complex restorations, dental anxiety β whatever brings you here, we're ready to help.
Meet the TeamFrom a single crown to a complete full-mouth rehabilitation β most care handled in-house, one trusted team.
Implants replace the root itself β preserving jawbone, restoring function, and looking completely natural. We place and restore the majority of implants entirely in-house. For complex cases requiring sinus lifts or soft tissue grafting, we partner with trusted specialists and coordinate your care every step of the way.
A crown restores a damaged or weakened tooth to full strength and appearance. A bridge replaces one or more missing teeth with a fixed, non-removable solution anchored to adjacent teeth. High-quality porcelain matched to your natural color.
Our dentures are built with close attention to how you look, how you speak, and how you eat. We work with a local dental laboratory β not outsourced overseas β and stay closely involved throughout your case, which means better communication, faster adjustments, and a result that's held to the standards we'd expect for our own patients.
Full mouth rehabilitation often requires a team. We coordinate and guide the overall treatment plan β working alongside trusted specialists as needed. Once the foundational work is complete, we bring everything together with the restorative work, delivering a cohesive, beautiful final result.
You don't need something to be broken to want it to be better. Veneers, whitening, and Botox for the smile you've always envisioned.
Ultra-thin custom shells bonded to the front of your teeth β instantly transforming color, shape, size, and symmetry. Veneers address chips, gaps, discoloration, and unevenness in two to three appointments. Stain-resistant, natural-looking, and built to last.
Professional-grade whitening with custom-fitted trays delivers results that drugstore strips simply can't match. We'll guide you on the right approach if you have existing crowns or veneers to ensure an even, natural result.
major work. Internal bleaching of a single discolored tooth β combined with subtle edge smoothing β can make a dramatic improvement in just one or two appointments. Small changes, big impact.
Your dentist is uniquely qualified to administer Botox β with expert knowledge of facial anatomy and the jaw that most injectors don't have. We use Botox therapeutically for clenching and TMJ pain, and cosmetically to soften lines around the mouth and jaw.
If anxiety, fear, or a strong gag reflex has kept you from the care you need β we have a genuine solution most dental offices simply can't offer.
Most dental "sedation" means oral medication β you're still awake and aware. We offer something fundamentally different: Monitored Anesthesia Care (MAC) from Dr. Alexander Zilber, a board-certified anesthesiologist. You'll be completely relaxed, have no memory of the procedure, and wake up with your dental work finished.
Dr. Zilber and Dr. Rossis met during residency training at Maimonides Medical Center in Brooklyn, NY. Together and in private practice β making them a uniquely experienced team.
Dr. Zilber received further training in Critical Care at Massachusetts General Hospital in Boston. He is a board-certified anesthesiologist and provides Monitored Anesthesia Care β an intravenous sedation that can be supplemented with additional medications for optimal comfort.
Preventive care isn't just cleaning your teeth β it's protecting your overall health, catching problems early, and ensuring your dental work lasts for decades.
We do far more than clean teeth β we screen for oral cancer, evaluate bite and jaw health, assess existing restorations, and look for early disease when it's easiest and least expensive to treat.

General Dentist Β· Founder
Dr. Rossis has been practicing dentistry for over 20 years, and her passion for the work and for the people she treats hasn't dimmed for a moment. She earned her dental degree from Temple University School of Dentistry and completed her residency at Maimonides Medical Center in Brooklyn, NY, where she developed the clinical foundation that defines her approach: thorough, thoughtful, and always centered on the patient in front of her.
Dr. Rossis isn't just a dentist in Malvern, she's a neighbor. She lives in the area, her children have attended Great Valley Schools, and she chose to build her life and her practice here.
Those who know her well would say the line between "inside" and "outside" the office is blurry at best β a reflection of how much she genuinely cares about getting it right for every patient. When she's not thinking about her practice, she's with her family or planning the next great trip.
