He is trained to provide IV and Oral Conscious sedation to provide comfort to those who are anxious and fearful visiting the dentists. 

With thousands of implants placed,and thousands of new life changing smiles, Dr. Annese frequently flies all over the country and is asked to lecture, speak, and train other doctors to be able to provide the care he provides here at North Billerica Smiles.. Doctors fly in and also spend days at the office to see the newest technology and to learn. Dr. Annese truly has a passion for providing the best dental care to his patients and elevating the dental profession as a whole.

In his free time Dr. Annese enjoys coaching his son Bennet’s t-ball and hockey teams, taking his daughter Adeline to her dance show practices, chasing around his crawling daughter Nora, and enjoying skiing, traveling and a glass of wine with his wife Allison.
