Throughout the day, plaque (a sticky film that forms on the surfaces of your teeth) and bacteria build up inside your mouth. Even though this is a natural process, having an overabundance of each can quickly lead to oral health issues. With regular brushing and flossing, you can keep both at bay.>> Learn more about professional dental cleanings


Brushing and flossing your teeth every day, along with regular dental visits, are essential habits for preventing serious oral health issues such as gum disease and tooth decay. However, even with proper preventive measures, problems can still occur. The longer these problems go undiagnosed and untreated, the worse they become, leading to serious infections and missing teeth. >> Learn more about professional dental exams


A visual inspection of your mouth will give us some clues, but it is only a part of a larger picture. There are many parts of your mouth that cannot be seen, such as the areas between your teeth and under your gums. At National Dental Williston Park, we can see these hidden structures thanks to the assistance of digital X-rays. >> Learn more about digital radiography


Cleanings are done as a measure to prevent gum disease from occurring. We recommend at least two cleanings a year. During your cleaning, we scrape the surfaces of your teeth, removing plaque, tartar, and bacteria buildup. We can reach the areas that might go overlooked. Cleanings are designed to prevent gum disease and other oral health issues from occurring in the first place. >> Learn more about periodontal care

It is a deadly disease, especially if it’s not detected (and treated) early. Only half of those diagnosed annually survive longer than five years. Early detection is essential for increasing your chances of remission. >> Learn more about oral cancer screenings
