Gentle Family Dentistry: Lawton/Ft. Sill now offers online patient registration forms. Dr. William Carter, Jr. is the principle dentist of the practice and is proud to be the first clinic to streamline services offered to patients. Even more exciting is the capability to port patient records and files with partner pratices. No longer is information faxed or mailed. With the advent of our patient portal, digital x-rays, and secure portal — patients and partners can easily access records as permitted.
