General Dentistry

Most people are familiar with the standard, traditional dentist practice where you can hear whirring drills and muffled question-and-answer sessions between the dentist and patient. At Locust Valley, we strive to make our practice unique, which is why we intentionally designed the patient experience to be soothing, relaxing, and personalized to your needs. Whether its helping distract yourself from the process with noise-cancelling headphones or creating a calm atmosphere with aromatherapy, we want to make your regular dental checkups to be a thing to enjoy, if not look forward to.

Our dental hygienists are trained to use gentle cleaning and polishing techniques to keep your teeth bright, healthy, and plaque-free while designing the perfect smile for your healthy teeth and gums.
