What sets Dr. Francis J. Del Casino and Dr. John D. Buonasera apart from other dentists in the United States?
Their patient-first philosophy, state-of-the-art CEREC same-day crowns, and IV sedation certification allow the Westbury, NY team to deliver pain-free, one-visit restorations that most U.S. practices still outsource to distant labs.
How can I verify their credentials before booking an appointment?
Both doctors are board-certified members of the American Dental Association and NY State Dental Association, and you can confirm their licenses instantly on the New York State Education Department online portal or by calling their office at +1 516-333-1177.
Do they accept nationwide PPO insurance plans?
The Maple Ave office files claims for over 150 national PPO networks—including Delta Dental, MetLife, and Aetna—and offers zero-interest CareCredit financing for any U.S. patient whose plan leaves an unpaid balance.
Is same-day emergency treatment available for out-of-state visitors?
Travelers landing at JFK or LaGuardia can reach the Westbury, NY location in under 25 minutes, and the doctors reserve daily emergency slots for fractured teeth, lost fillings, or acute infections, often completing permanent repairs before the patient’s return flight.
