Dr. Buono Brings Comfortable Dentistry to Long Island
Our Featured Dental Procedures
Veneers
Crafted from ultra-thin and incredibly strong porcelain, 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. Dr. Buono is renowned for providing patients with consistently stunning porcelain veneers results.
Dental Implants
Dental implants replace the roots of missing teeth in order to support 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.
Invisalign
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 negative impact on 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.
