Dr. Thomas Baron has been providing comfortable, relaxed, and pain-free dental treatment to his Cincinnati area patients for over 25 years. Experienced in all aspects of general dentistry, Dr. Baron often uses IV Sedation to allow his patients to receive a wide range of dental treatment in a single appointment, while they sleep. He has additional training and expertise in root canal therapy ,often combining it with IV sedation to completely take the fear out of this tooth-saving procedure. Patients who are apprehensive, have had negative dental experiences in the past, have strong gag reflexes, or just prefer not to be awake during treatment benefit tremendously from this approach.
