Story
“I cannot count how many people came to me after being lied to by their dentist. Year after year, I kept hearing the same version of the story, and one day I decided to launch Greatest Smile Dentistry. I wanted to create a place where trust is the foundational pillar of society, and of how we do business. I wanted to show people that it’s possible to have a dentist you can trust, a dentist that has your best interest at heart. Greatest Smile Dentistry, a new way of caring for patients.”

More About Dr. Ericka Dangelo
Aesthetic and Restorative Dentistry
Dr. Ericka Dangelo’s journey in dentistry began from a deeply personal experience.
As a child in São Paulo, Brazil, her family could not afford private orthodontic care. The only option was treatment at a university clinic. At nine years old, she became a patient there — and the transformation of her smile changed her confidence and the way she saw herself.
That experience inspired her life’s purpose.
Years later, Dr. Dangelo returned to that same university — this time as a dental student — determined to help others experience the same life-changing impact that a beautiful smile can bring.
Education and Advanced Training
Dr. Dangelo earned her dental degree in São Paulo and continued her academic path with a Master’s degree in Biomaterials, developing advanced knowledge of the materials and techniques that ensure long-lasting, high-quality aesthetic results.
She later owned and operated a successful private practice in Brazil, where she focused on:
Smile makeovers
Porcelain restorations
Facial aesthetics, including Botox and dermal fillers
Comprehensive aesthetic treatment planning
Seeking the highest level of clinical excellence, Dr. Dangelo moved to the United States to complete an Advanced Education in General Dentistry (AEGD) at the University of Florida — one of the most competitive programs for internationally trained dentists.
During her residency, she was selected as Chief Resident, a distinction that reflects leadership, clinical excellence, and dedication to patient care.
Philosophy of Care
For Dr. Dangelo, dentistry is not only about teeth.
It is about facial harmony, confidence, and quality of life.
Her approach combines science, advanced technology, and artistic vision to create results that look natural, balanced, and personalized to each patient’s facial features.
Her goals for every patient are:
A comfortable, personalized experience
Natural, aesthetic, and long-lasting results
A transformation that enhances confidence and self-image
Because when people feel confident about their smile, it positively impacts their personal life, social interactions, and professional opportunities.
Areas of Focus
Dr. Dangelo works with patients seeking comprehensive and high-level aesthetic care, including:
Porcelain veneers
Full mouth rehabilitation
Complex restorative cases
Digital smile design
Implant restorations
Facial harmonization with Botox and fillers
Dr. Dangelo’s vision is to become a trusted reference in high-end aesthetic dentistry in Miami, delivering personalized, boutique-level care and life-changing smile transformations.
Her mission is simple:
To create beautiful, natural smiles that help patients feel confident, empowered, and proud to share them.
