Cadent iTero 3-D Intraoral Scanner

Louis J. Buono, DDS, was the first dental practice in the world to offer the Cadent iTero® Scanner. Using precision 3-D laser technology, the Cadent iTero ensures incredibly accurate digital impressions for dental restorations including crowns, bridges, veneers, inlays, onlays, and implant abutments.

Digital X-Rays

The safety, convenience, accuracy, and flexibility of digital x-rays simply cannot be matched by traditional X-ray imaging. Digital x-rays expose you to far less radiation and give Dr. Buono a nearly instantaneous overview of your current state of oral health. Any area identified as being a potential issue can be enhanced in real-time so that our dentist can make an accurate diagnosis. He can share the images with you so that together, you can make an educated decision about your dental treatment.

Sapphire® Plus Lesion Detection

As part of our commitment to the health of our patients, Dr. Buono uses the revolutionary Sapphire light system to detect oral cancer and pre-cancerous lesions.

Early detection is the key to oral cancer. Regular screenings are the best way to discover this dangerous disease at its earliest stages when it is still highly curable. This device allows Dr. Buono to identify lesions below the surface before they produce any symptoms so that patients can receive prompt treatment to eliminate any potentially cancerous growths.

Our Featured Dental Procedures


Crafted from ultra-thin and incredibly strong porcelain shells, veneers conceal imperfections that can leave your smile appearing unhealthy. Veneers are an excellent solution for patients who want to enhance their smile in a short amount of time because they look, feel, and shine just like natural teeth. Dr. Buono is renowned for providing patients with consistently stunning results thanks to porcelain veneers.

Dental Implants

Dental implants are titanium posts that replace the roots of missing teeth in order to securely fix a restoration such as a crown, bridge, or denture. Dr. Buono is a master dentist who can restore dental implants with high-quality prosthetics that look, feel, and function like natural teeth. He works with a trusted oral surgeon to complete the surgical phase of the procedure.

Dental Crowns

Our metal-free dental crowns are made of advanced dental ceramics that repair and protect damaged, weakened, or misshapen teeth. An incredibly versatile treatment, dental crowns can improve the health and aesthetics of your smile. Our dentist uses state-of-the-art digital impressions to create crowns that seamlessly blend into your smile and complement your bite. Dr. Buono works with a boutique dental lab that is widely recognized for producing incredibly durable and amazingly life-like restorations

Crooked, crowded, or misaligned teeth can leave you embarrassed with your smile. Braces are bulky and uncomfortable, and if you are a teen or an adult, you may feel too old for braces. Invisalign® uses a series of clear aligner trays to bring your teeth into optimal position. These trays are 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 good candidate for Invisalign.

Teeth Whitening

A smile affected by yellowed or discolored teeth can have a tremendous negative impact 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.
