In this brief video, Dr. Katie To, the Wellness Dentist, explains that her practice collects a saliva sample from every patient at each visit and examines it under a microscope. By analyzing the microscopic slide, she claims the team can assess overall health indicators such as immune function, nutrition, hydration, and sleep quality, and then customize the dental treatment plan and at‑home care recommendations accordingly. She notes that a patient’s health can improve or decline between visits, so she encourages patients to ask to see their own slide during appointments. The video ends with a call to like the video and follow Dr. To for more health tips.
