Advanced Dental Technology

Our office uses the most advanced dental technology available. We were the first dental practice in the world to offer the Cadent iTero® Scanner, which uses precision 3-D laser technology to take digital impressions right in the office! To further promote comfortable and efficient care, we also use:

  • Digital X-rays: Digital x-rays allow us to create precise images while reducing radiation exposure.
  • Sapphire® Cancer Detection Light: Our dentist uses this tool to detect potentially cancerous oral lesions in their earliest stages.

Specialized Dental Treatments

Porcelain Veneers

Veneers are ultra-thin porcelain shells that cover the front surface of chipped, stained, or misshapen teeth. Because they look, feel, and shine just like natural teeth, veneers are an excellent solution for patients who want to enhance their smile in a short amount of time. Because of his consistently stunning results, Dr. Buono is widely known for his work with porcelain veneers.

Dental Implants

Dental implants are tiny titanium posts that are designed to replace the roots of missing teeth. Dr. Buono is a master restorative dentist who can restore dental implants with high-quality prosthetics that look and feel like natural teeth. He works with a trusted oral surgeon to complete the surgical phase of the procedure, which typically spans several appointments.

Dental Crowns

A dental crown is a porcelain restoration that covers a damaged, weakened, or misshapen tooth. This treatment is incredibly versatile and can improve the health and aesthetics of your smile. Our dentist uses digital impressions to create crowns that complement your bite. He also works with a boutique dental lab that is widely recognized for its high-quality results. 

Learn More about Dental Crowns


Crooked, crowded, or misaligned teeth can make you feel self-conscious. If you are a teen or an adult, you might feel that you are too old for braces. Invisalign® is a discreet, comfortable, and flexible alternative to traditional orthodontic treatment. During a consultation at our Long Island, NY, office, our dentist can examine your smile and determine if you are a candidate.

Teeth Whitening

Yellowing or discoloration can make your smile look unhealthy and decrease your self-confidence. Professional teeth whitening is an efficient and affordable way to brighten your smile and boost your self-esteem. Our dentist uses Philips ZOOM!®—an advanced whitening product that can brighten your smile by up to eight shades in just 45 minutes.
