After completing his undergraduate studies at Catholic University, Dr. DeNigris earned his dental degree from Georgetown University School of Dentistry in 1980, graduating at the head of his class. Maintaining an active membership in the American Dental Association, and Academy of General Dentistry, Dr. DeNigris has continued to remain current in the field with a passion for continuing education, having completed hundreds of hours of advanced training in all aspects of dentistry. As the second generation of dentists in his family, Dr. DeNigris carries on a family tradition of providing exceptional quality oral care, with a compassionate, patient-centered approach. When he’s not busy practicing dentistry or furthering his skills, Dr. DeNigris enjoys racing sailboats, and fishing—although not necessarily at the same time!

Proactive when it comes to your oral health, the office of Mark A. DeNigris emphasizes preventive oral care. As a proven method, effective at helping patients prevent the development of harmful dental conditions, your dentist would like to save you the need for extensive therapy if it can be avoided. Encouraging patients to stop in for semiannual exams and professional teeth cleanings, your dentist can keep a close watch over your oral health. With regular monitoring of the teeth, gums, and jaws, the likelihood of spotting dental conditions early on, when they’re simplest to treat, is greatly increased. Imparting his knowledge about dental hygiene and methods for care at home, Dr. DeNigris is an excellent teacher when it comes to brushing and flossing methods for patients at any age, or state of oral health. Complementing your at-home care with teeth cleanings, he will work with you to help prevent the onset of dental decay and gum disease, two of the most common dental ailments in the nation. For pediatric patients, Dr. DeNigris makes visiting the dentist fun, and takes additional measures to help ensure the continued oral health of your children.

At the office of Mark A. DeNigris DDS, we offer the latest restorative and cosmetic options for your teeth. Whether your teeth are damaged as a result of injury, decay, or root canal therapy, we provide the most cosmetically appealing fillings, crowns, and bridges for seamless results. Our crowns are completely customized, tailor made to the exact shade, shape and proportions of your natural teeth, and are extremely lifelike in appearance. Providing partial and full dentures, as well as dental implants for the replacement of missing teeth, you can trust that the most leading edge treatment solutions will be available. For eligible patients, dental implants provide an exceptional solution for replacing missing teeth. Unparalleled in their ability to replicate the form, function, and feel of natural teeth, dental implants also help to preserve your natural facial contours. Your dentist in Syosset also provides All-on-4, which provides permanent replacement for an entire dental arch through the use of a custom finalized bridge, secured by four strategically placed dental implants. All-on-4 is an excellent solution for replacing missing teeth, retaining the health benefits of dental implants and the cosmetic and functional benefits of fixed bridgework.

If you’ve been considering whitening your teeth, we offer professional grade whitening treatment, for one of the fastest and most effective options available. Many patients opt for the carefree convenience of an in-office treatment, personally administered by your Syosset dentist. For eligible patients at any age, we also offer orthodontic treatment with Invisalign. Aligning your crooked, spaced, or crowded teeth can make all the difference, not only in the appearance of your smile, but in your overall oral health as well.
