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.

We use the most current techniques and equipment, including flawless infection control; warm gutta percha; ultrasonic root end preparation in apical surgery; digital (low radiation) radiography; and the revolutionary endodontic operating microscope.

Our practice adheres to the highest standards of infection control in accordance with CDC and OSHA guidelines. We utilize the most current strict sterilization protocol to eliminate any risk of cross-contamination. All of our equipment is sterilized prior to treating each patient and  sterilization equipment is carefully monitored for 100% effectiveness. In addition, we use only safe and effective materials in connection with your root canal treatment.

For the benefit of our patients,

we are unique in providing:

•              Specialization in both Endodontics (root canal therapy) and Dental Implantology.

 •              Utilization of low radiation/high resolution  digital x-ray technology. (effecting an 80% reduction in radiation exposure).

 •              Secure on-line access of your records and radiographs for your general dentist, to ensure continuity of treatment. 

 •              All levels of anesthesia from low detection local anesthesia to general anesthesia.

 •              Utilization of the endodontic operating microscope in virtually all procedures.

 •              Continuous monitoring of all patients during treatment for heart rate, blood pressure and oxygen saturation utilizing state of the art pulse oximeters.
