Practice Profile
Our primary concern is to alleviate apprehension and provide the finest of care as comfortably as possible for our patients. Every patient is important to us and benefits from the most thoughtful care and the current technology. Our office is widely recognized as a leader in caring for the highly anxious and phobic patient. We perform all procedures utilizing low detection local anesthesia and, if desired, oral or intravenous sedation, nitrous oxide (laughing gas) or general anesthesia. Our specialty includes root canal therapy to retain natural teeth and implant placement to replace missing teeth. Dr. Grenn personally takes the time to thoroughly describe each step of our procedures so that our patients are fully informed and is available at any time to address questions before or after treatment.
