“I have always put the patient’s best interests forward. During the initial consultation, the patient can be rest assured that I will listen sincerely and try to address his or her concerns. I will develop a treatment that will address the referring dentist’s concerns and the patient’s chief complaint. I will explain every step of the process to restoring the dental health of the patient’s gum tissue and bone levels.”
